We would kindly like to announce the 1st workshop on ?Data Science for GNSS Remote Sensing?. The meeting will be hosted by the German Research Centre for Geosciences GFZ in June 2022. There has been recently a rapid progress in Earth observation using GNSS signals from numerous ground and satellite based platforms as well as modern data scientific approaches for their analysis, including machine learning and data assimilation techniques. We believe it is the right time to gather scientists interested in interdisciplinary activities linking these two research areas to foster a creative and intense scientific exchange and collaborations. Our ultimate goal is the provision of advanced and versatile GNSS Remote Sensing data products on different spatio-temporal scales for Earth System science and related operational applications to advance early warning systems and numerical weather forecasts. Please feel free to visit our workshop website www.D4G-2022.de .The meeting will take place on the historic ?Telegrafenberg? in Potsdam on June, 13-15, 2022. At the moment, we plan and strongly hope for a face-to-face meeting. However, we carefully observe the pandemic situation and will adapt the meeting format accordingly. Please feel free to forward this announcement to your colleagues. Looking forward to seeing you in Potsdam!

The session conveners: Rosa Pacione, Maximilian Semmling, Henrik Vedel, Kyriakos Balidakis, Norman Teferle ------------------------------------------------------------ Geodesy contributes to atmospheric science by providing some of the essential climate variables of the Global Climate Observing System. Water Vapor (WV) is currently under-sampled in meteorological and climate observing systems. Obtaining more high-quality humidity observations is essential to weather forecasting and climate monitoring. The production, exploitation and evaluation of operational GNSS-Met for weather forecasting is well established in Europe due to 20+ years of cooperation between the geodetic community and the national meteorological services. Improving the skill of numerical weather prediction (NWP) models to forecast extreme precipitation requires GNSS products with a higher spatio-temporal resolution and shorter turnaround. Homogeneously reprocessed GNSS data (e.g., IGS repro3) have high potential for monitoring water vapor climatic trends and variability. With shortening orbit repeat periods, SAR measurements are a new source of information to improve NWP models. Using NWP data within real-time (RT) GNSS data analysis can initialize PPP algorithms, thus shortening convergence times and improving positioning. GNSS signals can be used for L-band remote sensing when Earth-surface reflected signals are considered. GNSS-R contributes to environmental monitoring with estimates of soil moisture, snow depth, ocean wind speed, sea ice concentration and has the potential to be used to retrieve near-surface WV. We welcome, but not limit, contributions on: ?Estimates of the neutral atmosphere using ground- and space-based geodetic data and the use thereof in weather forecasting and climate monitoring ?Retrieval and comparison of tropospheric parameters from multi-GNSS, VLBI, DORIS and multi-sensor observations ?Now-casting, forecasting, and climate research using RT and reprocessed tropospheric products, employing numerical weather prediction and machine learning ?Assimilation of GNSS tropospheric products in NWP and in climate reanalysis ?Production of SAR tropospheric parameters and assimilation thereof in NWP ?Homogenization of long-term GNSS and VLBI tropospheric products ?Delay properties of GNSS signals for propagation experiments ?Exploitation of NWP data in GNSS data processing ?Techniques for soil moisture retrieval from GNSS data and for ground-atmosphere boundary interactions ?Detection and characterization of sea level, snow depth and sea ice changes, using GNSS-R ?Studying the atmospheric water cycle employing satellite gravimetry.

So far, the EGU General Assembly 2022 is still planned as a hybrid meeting with an in-person component in Vienna, however it might still be decided to switch to a virtual-only meeting if the pandemic situation makes it necessary (see https://www.egu.eu/news/883/update-on-egu22-hybrid-meeting-still-planned/). In case that EGU2022 will indeed have an in-person component, please be aware that this session is scheduled as an "oral/poster session" which means that it is adapted to in-person participation only (including on-site oral presentations accompanied by a physical poster session). However, there will be the possibility of uploading presentation materials (including pre-recorded presentations) and there will be an online discussion forum for each presentation to give online-only participants the chance to view all presentations and to interact with the presenters. Additionally, the EGU Programme Committee is currently looking into several potential solutions for abstracts submitted to oral/poster sessions by authors that indicate a preference for virtual participation. So despite these somewhat still unclear circumstances, we encourage everyone to submit an abstract to our session if you think that it is the most appropriate place to present your results. For further information on the session please visit: https://meetingorganizer.copernicus.org/EGU22/session/42838 Please be aware of the abstract submission deadline which is 12 January 2022, 13:00 CET.

The session is planned as an "oral/poster session" in case EGU22 will have an in-person component, as it is at the moment still planned. But there will also be the possibility of uploading presentation materials (including pre-recorded presentations) and there will be an online discussion forum for each presentation to give online-only participants the chance to view all presentations and to interact with the presenters. We thus encourage you to submit an abstract to this dedicated orbit session irrespective of your preference for an in-person or virtual participation. Session description: Precise orbit determination is of central importance for many applications of geodesy and earth science. The challenge is to determine satellite orbits in an absolute sense at the centimeter or even sub-centimeter level, and at the millimeter or even sub-millimeter level in a relative sense. Four constellations of GNSS satellites are available and numerous position-critical missions (e.g. altimetry, gravity, SAR and SLR missions) are currently in orbit. Altogether, outstanding data are available offering new opportunities to push orbit determination to the limit and to explore new applications. This session aims to make accessible the technical challenges of orbit determination and modelling to the wider community and to quantify the nature of the impact of dynamics errors on the various applications. Contributions are solicited from, but not limited to, the following areas: (1) precise orbit determination and validation; (2) satellite surface force modelling; (3) advances in modelling atmospheric density and in atmospheric gravity; (4) advances in modelling earth radiation fluxes and their interaction with space vehicles; (5) analysis of changes in geodetic parameters/earth models resulting from improved force modelling/orbit determination methods; (6) improvements in observable modelling for all tracking systems, e.g. SLR, DORIS, GNSS and their impact on orbit determination; (7) advances in combining the different tracking systems for orbit determination; (8) the impact of improved clock modelling methods / space clocks on precise orbit determination; (9) advances in modelling satellite attitude.

In particular, we would like to draw the attention to a session, organized by the COSPAR Panel on Satellite Dynamics. The title of the session is "Satellite Dynamics - new Developments and Challenges for Earth and Solar System Sciences". The aim of the Panel on Satellite Dynamics is to support activities related to the detailed description of the motion of artificial celestial bodies. This goal should be achieved by improving the current theories of motion and by evaluating their determining forces in a more sophisticated way. Detailed theoretical understanding of the dynamics of satellites should coincide with the results of precise tracking in order to obtain the most precise knowledge possible of the orbit and the corresponding orbital positions. The scope of the Panel on Satellite Dynamics entails the positioning of a wide range of objects in space, including Earth orbiting satellites for Earth observation such as GRACE-FO, Swarm, Jason series, and the Copernicus Sentinels, and navigation satellite systems such as GPS, GLONASS, Galileo, Beidou, QZSS or tracking systems such as SLR and DORIS. In addition, positioning plays an important role in the success of the continuously growing number of today's and tomorrow?s missions to explore the Solar System. Recent and future missions have to deal with complex trajectories and innovative propulsion and breaking techniques to visit multiple bodies (e.g., Cassini, Dawn, JUICE), small unconventional bodies (e.g., Rosetta, OSIRIS-REx, Lucy), and harsh and unknown environmental conditions challenging our technical capabilities (e.g., Messenger, Venus Express, BepiColombo, JUNO). Both advances in the modeling of spacecraft dynamics and the theoretical understanding of space observables (e.g., range, Doppler, VLBI, optical) are required to allow for a more efficient exploration and a deeper understanding of our Solar System. Limiting errors in Precise Orbit Determination (solar radiation pressure, time variable gravity fields, phase center corrections, attitude variations, etc...) are of critical interest for many stakeholders. Moreover, formations of satellites are being realized and proposed for Earth observation and fundamental sciences, that impose very severe constraints on (relative) positioning and orbit and attitude control solutions (e.g. micro-propulsion). Mini-satellites and cubesats also represent a new frontier for both Earth and planetary exploration, posing new challenges as well as new opportunities. Satellite orbit determination requires the availability of tracking systems, well established reference frames and accurate station coordinate solutions, detailed force and satellite models, and high-precision time and frequency standards. Contributions covering all recent developments and plans in ground, satellite or probe positioning and navigation are solicited as well as contributions on current progress on establishment, maintenance and improvement of reference systems in Geo- and planetary sciences.

Compared to the established BRDC00IGS and BRDM00DLR multi-GNSS broadcast ephemeris files made available so far, the new RINEX 4 files offer a diverse set of new CNAV message types transmitted by GPS, QZSS, and BeiDou-3. In addition, they provide comprehensive support of broadcast system time offsets, ionosphere model parameters and Earth orientation parameters made available in the various navigation data. Data for the new BRD400DLR product are extracted from raw and decoded navigation messages of a global set of receivers and merged into daily files that are made available within a few hours after midnight. Compared to RINEX 4, the RINEX 4 navigation file format includes various format changes but retains the basic layout for all established navigation messages to facilitate adaptation of corresponding software for reading and processing navigation files. A detailed format description is provided at https://www.igs.org/wg/rinex/#documents-formats. We hope that the new BRD400DLR files offer a valuable data source for users of the new navigation signals and help to familiarize users and manufacturers with the new format. BRD400DLR files are made available retrospectively starting 1 January 2022. Along with their introduction, provision of the former "BRDX00DLR" product will be terminated. The latter had been introduced following the first IGS CNAV test campaign (see https://cddis.nasa.gov/archive/gnss/data/campaign/cnav/2013/06/aaaReadme.txt) and served as a temporary platform for exchanging GPS CNAV data over the past years. With the availability of the new comprehensive navigation data files in the official RINEX 4 format, BRDX has clearly become obsolete and will be discontinued. The established BRDM00DLR navigation files in RINEX 3 format represent a subset of information from the new BRD400DLR product covering all legacy navigation message. They will be continued for compatibility with existing software until further notice. The daily RINEX 4 navigation files will be accessible through the IGS data centers at the established locations for merged navigation files, e.g. https://cddis.nasa.gov/archive/gnss/data/daily//brdc/ ftp://igs.ign.fr/pub/igs/data// https://igs.bkg.bund.de/root_ftp/IGS/BRDC/// with and denoting the desired year and day of year.

I saw pictures on Twitter yesterday of people carefully sweeping a runway by hand! The closest CORStation we at the US National Geodetic Survey have to Tonga is ASPA in Pago Pago, American Samoa, but that station has an old receiver which is behaving badly. Once we get ASPA operating again, I do not expect to see any crustal displacement. I'll ask friends at Jet Propulsion Laboratory (cc'd) if they have any SAR interferograms of Tonga which may tell you if your islands were deformed. Just days before the massive explosion, I was coordinating with a surveyor who will do work at Midway Island later this year to help get MQSL back online and look for a site to install a second CORS for redundancy in the event MQSL was damaged by a tsunami or suffered an outage. The Tonga event is a very good lesson for us all to have better and expanded geodetic infrastructure throughout the Pacific.

From about 12:00 UTC to 16:30 UTC the CDDIS data upload facility and data distribution (https) were affected by an internal NASA DNS outage. Our data distribution using ftp-ssl, GNSS real-time activities and all other services were unaffected. CDDIS was fully operational during this time but unfortunately all DNS lookups in our private IP space failed. The system that failed was a triply redundant system. Both the primary and secondary systems went down and the tertiary system experienced issues with response time. As such you could get to CDDIS from the outside (public IP space), but any activity that relied on services for load balancing, authentication, etc would fail. As this is a NASA agency-maintained resource, CDDIS (and other projects) were at the mercy of the agency to get corrected. I truly apologize for this outage. If you have any questions or concerns, please feel free to reach out to me to discuss.

Data products may be found through browsing the site, or downloaded directly from the main product index at https://maia.usno.navy.mil/ser7/ In addition to the overhauled website design, we have also made our services more robust and secure: * We have moved to distributing our products via HTTPS for increased data integrity and security of data transmission. Please note that the unsecured HTTP protocol is no longer supported. * Our website and data are now hosted on an Amazon Web Services Cloud environment, improving server up-time and reliability. * We have consolidated our publication servers to a single instance, removing any confusion over the "best" server to use. The former backup site (toshi.nofs.navy.mil) has been retired and will not be returning. * A new version of the EO Matrix Calculator web application with an improved interface is now available at https://maia.usno.navy.mil/matrix-calculator During the outage, we hope you were able to continue receiving our products through NASA CDDIS, which graciously provided a mirror for our data while our main site was down. While this was not ideal for some customers, we thank you for your patience and understanding while we made several improvements to our website. All data products will continue to be uploaded to the CDDIS mirror at https://cddis.nasa.gov/archive/products/iers/ , so users should not expect any of their current links or data retrieval scripts to break. However, we encourage users to review their options and begin transitioning to https://maia.usno.navy.mil as their primary source if this new site meets their needs, as this site will receive our publications more promptly and directly, and does not require login to any user accounts.

Due to circumstances beyond our control, we will unfortunately need to move our 2022 Workshop to a fully virtual format. While we will all miss seeing each other in person, we will use this change of circumstances to help us refocus the IGS Workshop back to being just that ? a community workshop. We will be operating on a compressed schedule to try to be inclusive to as many time zones as possible, and condensing our workshop program to aspects that are the most critical to the function of our Service, specifically a small number of keynote presentations by luminaries and innovators in our community, supported by a comprehensive agenda of working group and/or topical collaboration sessions. The emphasis will be on bringing our community together to discuss key issues and brainstorm the next steps toward a multi-GNSS IGS in service to our global community. The virtual workshop will take place, as scheduled, the week of 27 June to 1 July, 2022. Key changes include: - Live Keynote presentations, with recordings made available after the workshop on IGS YouTube. - Targeted WG/topical splinter sessions convened by IGS Working Group Chairs and community leaders - Plenaries/posters will not be held during this workshop, but are effectively already taking place (virtually) via the Tour de l?IGS Mini Workshop Series ; the next Tour de l?IGS is planned for late April. - We will plan to hold additional/enhanced sessions at the December 2022 AGU for in-person presentations, an Open AM/WG Meeting, and ?2022 Workshop Apr?s-Ski? networking event. We hope that this proposed workshop program will help the IGS workshop return to its unique place among our regular meetings, adding value and impact to our profession. *Please check our IGS Workshop 2022 event page periodically for additional event updates.* On behalf of the Local Organizing Committee and Scientific Organizing Committee, Best Regards, IGS Central Bureau -------------- next part -------------- An HTML attachment was scrubbed...

Howarth Local Organizing Committee C. Kotsakis, M. Chatzinikos, A. Bai, S. Psycha, G. Maltis, A. Pliatsika, D. Velissaridou, K. Griva Dear Colleagues, On behalf of the local organizing committee, I am honored to invite you to the IAG International Symposium on Reference Frames for Applications in Geosciences (REFAG 2022) which is organized by the Aristotle University of Thessaloniki under the scientific coordination of Commission 1 of the International Association of Geodesy. The symposium will be held in Thessaloniki, Greece on October 17-20, 2022. REFAG 2022 carries on the tradition of previous IAG dedicated symposia on Reference Frames, aiming to bring together leading experts from academia, public authorities and private sector with young scientists and students, to discuss current achievements and future prospects of geodetic reference frames and their scientific and societal impact. All details about the symposium, its scientific programe and venue are available at the symposium website:*www.refag2022.org*. _Scientific Programme_** The primary scope of REFAG 2022 is to address today's theoretical concepts of reference systems and their practical implementation by space geodetic techniques and their combinations, underlying limiting factors and novel approaches for future improvements, as well as their impact to Earth sciences and their applications. In particular, contributions from the following areas are strongly encouraged: - Global reference frames by individual space geodetic techniques and their combination, - Space geodetic measurements and mitigation of their systematic errors, - Geocenter motion and non-tidal loading effects, - Earth dynamics and novel reference frame representations, - Station kinematic models and position time series analysis, - Terrestrial and space geodetic ties for multi-technique combination, - Regional reference frames and related applications, - Maintenance of regional reference frames in active tectonic regions, - Celestial reference frames from single and multi-technique combination solutions, - Comparison and combination of Earth Orientation Parameters by different techniques, - Usage and challenges of geodetic reference frames for Earth science applications. The scientific program of the symposium will cover all topics related to the activities of IAG Commission 1 and its subgroups, including also other initiatives and projects which endorse the role of geodetic reference frames towards scientific exploration, sustainable development, climate monitoring and satellite navigation. _GGOS - UAW 2022_** The Unified Analysis Workshop (UAW) 2022 will be held successively with the REFAG 2022 Symposium in October 21-23, 2022. The UAW 2022 is co-organized by the IAG's Global Geodetic Observing System (GGOS) and the International Earth Rotation and Reference Systems Service (IERS) for the purpose of discussing issues that are common to all space-geodetic measurement techniques. For more details, see the workshop's website: https://ggos.org/event/unified-analysis-workshop-uaw-2022/. _Venue_ The symposium will be held at the Electra Palace Hotel, which is located at the heart of downtown Thessaloniki (https://www.electrahotels.gr/hotels/electra-palace-thessaloniki/). October is usually a period of high tourist acitivity for Thessaloniki, therefore an early registration and accomodation booking is highly recommended. More details about accomodation options and special prices for REFAG 2022 registrants are given at the symposium website. _Abstracts, presentations and papers_ Deadline for abstract submission is June 20, 2022; both the guidelines and the submission portal are available on the REFAG 2022 website. A non-refundable processing fee of 40 Euro is required for each abstract submission. Each abstract will be reviewed by the Scientific Committee and its eventual acceptance will be notified by e-mail to the corresponding author by July 20, 2022. Upon abstract submission, the corresponding author will have to indicate the preference for oral or poster presentation. However, the final decision on the form of presentation will be taken by the Scientific Committee during the abstract review. Guidelines for the full paper submission for peer-review and related formatting instruction will be available through the REFAG 2022 website. Accepted papers will be published by Springer as a volume of the official IAG Symposia series, see the link https://www.springer.com/series/1345. _Registration fee_ The following types of registration fees are available: - regular registration: 360 Euro - young researcher (age < 32 at Symposium): 220 Euro An additional 70 Euro fee will be charged to regular and young researcher registration in case of late registration (after July 25, 2022). The registration fee can be paid by bank transfer or by a credit card according to the information published on the REFAG 2022 website, and it includes: - symposium proceedings - ice breaker reception - coffee breaks and light snacks The REFAG 2022 is an official IAG meeting. Young scientists from IAG member countries may apply for the IAG Travel Award to assist them in presenting results of their research. For more details, please see https://iag.dgfi.tum.de/fileadmin/IAG-docs/Rules_for_Travel_Awards.pdf. _Social programme _ The scientific programme will be complemented with a social one, including an optional social dinner in one of Thessaloniki's fine restaurants. _COVID19_ The symposium is planned as a standard meeting with on-site attendance. In case of Covid-related travel restrictions, it will be possible to switch to a hybrid form (in this case, the registration fees for those attending online will be 50% of the standard ones). However, the physical form of the symposium will be strongly preferred. We look forward to welcoming you in Thessaloniki! C.

In the past, all 15-minute files (96 total per day) were stored individually. Going forward from June 15th ALL high-rate files older than 6 months in age will be consolidated into a single tar file per monument per day, along with the compression of the files being changed from Unix compress to gzip. Newer files (from the present to 6 months of age) will continue to be left in the current format of individual 15-minute files. As files age out, they will be tar and gzip compressed into the new format. More info can be seen on this page describing the process and naming conventions for files. https://cddis.nasa.gov/Data_and_Derived_Products/GNSS/high-rate_data.html Nominal timeline for all changes is as follows: 1. 15 Jun 2022 ? Conversion of all high-rate files from year 2001 and older will commence 2. 17 Jun ? 1 Aug ? Conversion of all high-rate files newer than year 2001 will commence from oldest to newest, i.e. 2002, 2003, 2004, etc. 3. 2 Aug 2022 ? All conversions should be completed up to the current date minus 6 months, i.e. 2 Feb 2022. 4. 3 Aug 2022 ? All high-rate files older than 6 months will then be converted on a daily basis into the new format. As per CDDIS?s agreement with the IGS, there will be a two-month period in which community feedback may be heard.

All interested individuals are invited to attend the meeting. The 2nd IAG Commission 4 Symposium brings together scientists, researchers and professionals dealing with the broad area of positioning and applications. For this purpose, it will facilitate the discussion of research that leverages current and emerging positioning techniques and technologies aiming at delivering both practical and theoretical solutions for engineering and mapping applications, GNSS-based technologies, sensors fusion, and atmospheric remote sensing, modelling, and applications, based on geodetic techniques. Recognizing the central role of Global Navigation Satellite Systems (GNSS) in providing high accuracy positioning information today and in the future, the 2nd IAG Commission 4 Symposium will focus on ongoing research for improving models and methods that enhance and assure the performance of GNSS-based positioning solutions for a wide range of geodetic applications. The 2nd IAG Commission 4 Symposium will be devoted to the discussion of theory, strategies and tools for modelling and/or mitigating the effects of interference, signal loss and atmospheric effects as they apply to precise GNSS and other space geodetic techniques. They will address the technical and institutional issues necessary for developing backups for GNSS, integrated positioning solutions, automated processing capabilities and quality control measures. Besides positioning, another focus of the 2nd IAG Commission 4 Symposium will be on remote sensing and modelling of the lower and upper atmosphere. The Space Geodesy and Ionosphere (SGI) Workshop in 2022 is embedded in this event. This symposium will be carried out in close cooperation with the International GNSS Service (IGS), the IAG Global Geodetic Observing System (GGOS) Focus Area ?Geodetic Space Weather Research?, as well as via linkages with relevant entities within scientific and professional sister organizations. The Symposium will be co-sponsored by the International Association of Geomagnetism and Aeronomy?s (IAGA) Inter- Divisional Commission on Space Weather and the Division II ?Aeronomic Phenomena? Working Group IIC ?Meteorological Effects on the Ionosphere?. Further partners are the Institute of Navigation (ION), the Technische Universit?t Berlin and the GFZ Potsdam.

The new format has been officially accepted by the IGS Governing Board on Dec 7, 2021. The IGS is moving forward to support this new standard. The IGS Infrastructure Committee (IC) has developed a transition plan to foster a short but safe transition. This transition phase has the primary goal to facilitate the acceptance of the new standard in the user community. It is anticipated to be completed within 6 months but depending on user feedback. The transition plan is available at: https://nextcloud.gfz-potsdam.de/s/WexMESPRwLpPGLH The first data centres are ready to accept GNSS data in the RINEX 4.00 format. To support the users of our data with the recommended transition, we kindly ask station operators to support this process. Please contact the IGS Central Bureau if you are able to submit RINEX versions 3 and 4 in parallel. You will receive further guidance on how to proceed with the uploads. Please do not switch to RINEX 4.00 only submission at this time. The first daily (station wise) RINEX 4.00 observation, navigation and meteorological files have been provided by GFZ and are available from DOY 2022-142 in the CDDIS and BKG archives. For now, they are converted from native RINEX 3.0x files. https://cddis.nasa.gov/archive/gnss/data/campaign/rinex4/daily/2022 https://igs.bkg.bund.de/root_ftp/IGS/obs_v4/2022/ Merged native RINEX 4.00 BRDC files (named BRD400DLR) have already been provided by DLR since the start of 2022. Users, in particular the IGS Analysis Centres, are advised to check and adjust their automated routines to support the processing of RINEX 4.00 files. Please report any problems back to the IGS CB.

The session has been designed as an interactive discussion that will assist the Infrastructure Committee in developing a vision and strategy to sustain and evolve the IGS tracking network, which many of you rely upon for the generation of world-class positioning products and scientific advancements. The focus of the session will be on trying to answer the question ?is the existing IGS tracking network fit-for-purpose?? To prepare for the discussion we have put together an overview of the existing network: https://nextcloud.gfz-potsdam.de/s/pyXyZN38X77Xo6i We would like you to think about the following questions: What should be the purpose of the IGS tracking network? i.e. What do you use the network for? Is it more than just the generation of IGS products? How should the IGS tracking network evolve to better support the changing needs of users? i.e. Does the existing network support all of your current and anticipated future needs (think in terms of geographic distribution, data quality, data availability, resilience, data products, scientific or societal trends)? The session will be held on the first day of the workshop (27 June) at 13:00 UTC. To register for the workshop please visit https://igs.org/igs-ws-2022 . If you are unable to attend the workshop, we would still welcome and appreciate your thoughts on the above. Please provide these via email to bradke at gfz-potsdam.de prior to the workshop.

Our previous announcement on this subject is listed below. Any questions or comments please direct to support-cddis at earthdata.nasa.gov. Dear Colleagues, On 15 Jun 2022, CDDIS will change the way in which GNSS high-rate (sub-hourly, 1-second sampling rate) files are stored in the CDDIS archive. In the past, all 15-minute files (96 total per day) were stored individually. Going forward from June 15th ALL high-rate files older than 6 months in age will be consolidated into a single tar file per monument per day, along with the compression of the files being changed from Unix compress to gzip. Newer files (from the present to 6 months of age) will continue to be left in the current format of individual 15-minute files. As files age out, they will be tar and gzip compressed into the new format. More info can be seen on this page describing the process and naming conventions for files. https://cddis.nasa.gov/Data_and_Derived_Products/GNSS/high-rate_data.html Nominal timeline for all changes is as follows: 1. 15 Jun 2022 ? Conversion of all high-rate files from year 2001 and older will commence 2. 17 Jun ? 1 Aug ? Conversion of all high-rate files newer than year 2001 will commence from oldest to newest, i.e. 2002, 2003, 2004, etc. 3. 2 Aug 2022 ? All conversions should be completed up to the current date minus 6 months, i.e. 2 Feb 2022. 4. 3 Aug 2022 ? All high-rate files older than 6 months will then be converted on a daily basis into the new format. As per CDDIS?s agreement with the IGS, there will be a two-month period in which community feedback may be heard.

We publish 4 levels of data products building upon our daily displacement time series from a combination of JPL and SIO GNSS solutions using common metadata from the SOPAC database. The daily time series and metadata can be viewed, coupled with a map interface, on MGViz, our new single-screen user application at MGViz.ucsd.edu (https://MGViz.ucsd.edu). Our products are archived at SOPAC (http://garner.ucsd.edu/pub/measuresESESES_products/) and CDDIS (https://cddis.nasa.gov/archive/GPS_Explorer/archive/). Please see the attached flyer and our Web pages at sopac-csrc.ucsd.edu/index.php/measures-2/ (https://sopac-csrc.ucsd.edu/index.php/measures-2/) for more information.? We have brief videos for MGViz and each product. The products include: (1)??? Combined daily displacement time series for about 3500 regional and global IGS stations, installed and maintained with geodetic quality and well-documented metadata. We have two main products (with different flavors trended, detrended, PCA-filtered, residuals). ???? The first is the result of extensive quality control and includes unmodeled time series where non-physical displacements and poor-quality data have been identified and corrected. ???? The second is a parametrically-fit time series, including slopes, offsets, postseismic motions, seasonal terms, with uncertainties for all parameters based on white and colored noise components.? Solutions for the longest-lived stations begin in 1992. (2)??? A list of ?problematic? stations that should be used with caution. (3)??? Weekly station velocities (for stations with more than 2.5 years of data) and coseismic displacements. (4)??? Weekly 3-D displacement grids interpolated from the median-filtered daily time series. (5)??? Weekly horizontal strain rate grids. (6)??? Modeled ETS transient events for Cascadia since 1994. (7)??? Water storage data for the Western U.S. since 2006. (8)??? 5-minute troposphere delay estimates from 1992 and precipitable water from 1995. (9)??? 100 Hz seismogeodetic and 1Hz GPS displacement and velocity waveforms for historical earthquakes.

Howarth Local Organizing Committee C. Kotsakis, M. Chatzinikos, A. Bai, S. Psycha, G. Maltis, A. Pliatsika, D. Velissaridou, K. Griva Dear Colleagues, On behalf of the local organizing committee, I am honored to invite you to the IAG International Symposium on Reference Frames for Applications in Geosciences (REFAG 2022) which is organized by the Aristotle University of Thessaloniki under the scientific coordination of Commission 1 of the International Association of Geodesy. The symposium will be held in Thessaloniki, Greece on October 17-20, 2022. REFAG 2022 carries on the tradition of previous IAG dedicated symposia on Reference Frames, aiming to bring together leading experts from academia, public authorities and private sector with young scientists and students, to discuss current achievements and future prospects of geodetic reference frames and their scientific and societal impact. All details about the symposium, its scientific programe and venue are available at the symposium website:*www.refag2022.org*. _*Scientific Programme*_** The primary scope of REFAG 2022 is to address today's theoretical concepts of reference systems and their practical implementation by space geodetic techniques and their combinations, underlying limiting factors and novel approaches for future improvements, as well as their impact to Earth sciences and their applications. In particular, contributions from the following areas are strongly encouraged: - Global reference frames by individual space geodetic techniques and their combination, - Space geodetic measurements and mitigation of their systematic errors, - Geocenter motion and non-tidal loading effects, - Earth dynamics and novel reference frame representations, - Station kinematic models and position time series analysis, - Terrestrial and space geodetic ties for multi-technique combination, - Regional reference frames and related applications, - Maintenance of regional reference frames in active tectonic regions, - Celestial reference frames from single and multi-technique combination solutions, - Comparison and combination of Earth Orientation Parameters by different techniques, - Usage and challenges of geodetic reference frames for Earth science applications. The scientific program of the symposium will cover all topics related to the activities of IAG Commission 1 and its subgroups, including also other initiatives and projects which endorse the role of geodetic reference frames towards scientific exploration, sustainable development, climate monitoring and satellite navigation. _*GGOS - UAW 2022*_** The Unified Analysis Workshop (UAW) 2022 will be held successively with the REFAG 2022 Symposium in October 21-23, 2022. The UAW 2022 is co-organized by the IAG's Global Geodetic Observing System (GGOS) and the International Earth Rotation and Reference Systems Service (IERS) for the purpose of discussing issues that are common to all space-geodetic measurement techniques. For more details, see the workshop's website: https://ggos.org/event/unified-analysis-workshop-uaw-2022/. _*Venue*_ The symposium will be held at the Electra Palace Hotel, which is located at the heart of downtown Thessaloniki (https://www.electrahotels.gr/hotels/electra-palace-thessaloniki/). October is usually a period of high tourist acitivity for Thessaloniki, therefore an early registration and accomodation booking is highly recommended. More details about accomodation options and special prices for REFAG 2022 registrants are given at the symposium website. *_Abstracts, presentations and papers_* Deadline for abstract submission is extended to*July 20, 2022*; both the guidelines and the submission portal are available on the REFAG 2022 website. A non-refundable processing fee of 40 Euro is required for each abstract submission. Each abstract will be reviewed by the Scientific Committee and its eventual acceptance will be notified by e-mail to the corresponding author*by July 30, 2022*. Upon abstract submission, the corresponding author will have to indicate the preference for oral or poster presentation. However, the final decision on the form of presentation will be taken by the Scientific Committee during the abstract review. Guidelines for the full paper submission for peer-review and related formatting instruction will be available through the REFAG 2022 website. Accepted papers will be published by Springer as a volume of the official IAG Symposia series, see the link https://www.springer.com/series/1345. _*Registration fee*_ The following types of registration fees are available: - regular registration: 360 Euro - young researcher (age < 32 at Symposium): 220 Euro An additional 70 Euro fee will be charged to regular and young researcher registration in case of late registration*(after July 30, 2022)*. The registration fee can be paid by bank transfer or by a credit card according to the information published on the REFAG 2022 website, and it includes: - symposium proceedings - ice breaker reception - coffee breaks and light snacks The REFAG 2022 is an official IAG meeting. Young scientists from IAG member countries may apply for the IAG Travel Award to assist them in presenting results of their research. For more details, please see https://iag.dgfi.tum.de/fileadmin/IAG-docs/Rules_for_Travel_Awards.pdf. _*Social programme* _ The scientific programme will be complemented with a social one, including an optional social dinner in one of Thessaloniki's fine restaurants. _*COVID19*_ The symposium is planned as a standard meeting with on-site attendance. In case of Covid-related travel restrictions, it will be possible to switch to a hybrid form (in this case, the registration fees for those attending online will be 50% of the standard ones).

The delay was caused by the failure in automatic run of a program that converted satellite broadcast navigation file to sp3 file. The products are now generated manually, and uploaded to global data centres. On a separate note, we have been experiencing difficulties in the timescale exchange for the rapid clocks (re-aligning the clocks to the IGS time scale) since GPS week 2216, dow 1. We are working to resolve this, but the products are still being available without the timescale exchange. I will notify you once this is resolved. Apologies for any inconvenience this may have caused.

Because of its high precision and cloud penetration capability, GNSS observations such as radio occultations (GNSS-RO) and the expanding network of ground stations provide high quality global atmospheric retrievals. These observations greatly contribute to numerical weather prediction (NWP) systems for accurate forecasts and extreme weather early warning nowadays. This session welcomes submissions including, but not limited to the following topics: 1. Earth science and applications on planetary boundary layer (PBL), deep convection and heavy precipitation, extreme weather events, climate model diagnostics, and aerosol distribution. 2. GNSS remote sensing technology advancement including novel observing concepts, instrument miniaturization, GNSS reflectometry, and other signals of opportunity (SoOP). 3. State-of-the-art retrieval algorithm developments such as sensor fusion/joint retrieval between GNSS and existing/emerging instruments, GNSS and alternative signal processing, tomographic algorithms, and new atmospheric product generation. 4. NWP application of GNSS remote sensing products, such as impact study, forward model development, and data product validation.

We are looking forward to your contribution by submitting an abstract to our session. Please note the Abstract submission deadline: 3 August at 23:59 EDT/03:59 +1 GMT. For more information about the 2022 Fall Meeting, please consult: https://www.agu.org/Fall-Meeting Best regards, Zuheir Altamimi (IGN-IPGP France) Jake Griffiths (US Naval Research Laboratory, Washington, DC, USA) Frank Lemoine (NASA Goddard SFC, Greenbelt, MD, USA) G010. Reference Frames: Determination, Usage, and Application The Earth is a dynamic planet. The quantification of many geophysical phenomena, e.g. sea level variations, co-and post-seismic deformation, glacial isostatic adjustment, local subsidence due to natural or anthropogenic causes, loading effects, ice sheet and glacier mapping, mitigation of natural hazards, but also precise orbit determination of artificial satellites, rely on the availability of a global terrestrial reference frame, such as the International Terrestrial reference Frame (ITRF). The session solicits contributions from scientists determining or using global reference frames for their applications, focusing on error budgets and other limiting factors. Papers from analysts of space geodetic techniques (DORIS, GNSS, SLR, VLBI) and their combination on their contribution to ITRF2020, are most welcome. Papers on the exploitation of past ITRF solutions and the newly published ITRF2020 are also encouraged. -------------- next part -------------- An HTML attachment was scrubbed...

In accordance with this goal, the IGS has continuously built up and expanded its multi-GNSS capabilities over the last decade. This includes both the integration of an ever-increasing number of multi-GNSS stations into the IGS network as well as the generation of multi-GNSS orbit, clock, and bias products to name just a few. On the other hand, the combination of products, which appears essential for the provision of robust and quality-controlled end-products to its users, is still limited to the legacy GPS and GLONASS constellations. While various IGS entities have studied product combination concepts and even generated prototype software tools and products in recent years, these efforts have not yet led to an operational generation of combined products covering the full spectrum of GNSS constellations supported by the individual analysis centers. At the same time, product combination for the four global navigation satellite systems is already routinely exercised by external entities, thus questioning the leading role of the IGS as the primary source for high-performance GNSS products. With this background, the installation of a new task force has been proposed at the recent IGS workshop, to coordinate and advance existing efforts for product combination across the various IGS bodies. Proposed tasks would include * Review and trade-off of existing concepts, algorithms, and tools for multi-constellation product combination within and outside the IGS * Quality assessment and identification of harmonization needs for the various (legacy and multi-GNSS) products to support combination (e.g. step size, availability of ERP, SINEX and attitude data, etc.) * Definition and consolidation of requirements for a harmonized IGS product combination tool and process covering the needs of different IGS entities. This should address both the type of products that need to be combined (orbit, clock, bias, coordinates, ERPs, etc.), the supported constellations (global vs. regional) and satellites (MEO/IGSO/GEO), the basic concepts and algorithms (e.g. frame alignment, Helmert transformations, VCE, reference signals and clock, etc.), as well as possible system-related aspects (proprietary vs. open source, platform, language, throughput, etc.) * Definition of roadmap and responsibilities for generation of a consolidated combination tool chain and the progressive build-up of a combined-product portfolio within the IGS This call invites IGS members and stakeholders across the various working groups and analysis centers to contribute to these goals. Membership to the task force assumes a binding commitment to actively support its work through analyses, discussions, development, and documentation. Please address your interest in participation to oliver.montenbruck at dlr.de who will coordinate the setup and initial work of the task force until a final decision on the task force leadership can be taken by its members. Applications should be received before 8 Aug 2022 to enable a timely formation of the task force and start of work.

As the title promises it shall become a platform for interactions between people that are using our products and those that are generating them. The conveners Allison Craddock (IGS CB, JPL, USA), Felix Perosanz (CNES, France), and Rolf Dach (AIUB, Switzerland) hope for many interesting contributions in order to establish an active exchange. Please be reminded that AGU abstracts may be submitted until August, 3rd 2022 via the AGU abstract submission form: https://agu.confex.com/agu/fm22/prelim.cgi/Home/0 More information about the event taking place again in Chicago, IL during 12-16 December 2022 can be found at: https://www.agu.org/Fall-Meeting See you in Chicago, best regards Allison, Felix and Rolf ---------------------------------------------------------------------- The full description of the session is as follows: "The International GNSS Service (IGS) provides a broad range of high-precision openly available geodetic products supporting diverse scientific applications for peaceful usage. The recently finished reprocessing effort (?repro3?) includes three out of the four currently fully deployed GNSS constellations: GPS, GLONASS, and Galileo. Developments to include additional GNSSs (BeiDou, QZSS, NavIC, etc.) are ongoing within the IGS. Advances in IGS product development may stimulate new multi-GNSS scientific applications in a wide range of potential applications including Earth rotation, tectonophysics, seismology and the earthquake cycle, glaciology and glacial isostatic adjustment, global environmental change, sea level, terrestrial water storage, time transfer, space weather and atmospheric science, disaster and tsunami early warning, and fundamental physics. The continuous improvement of IGS products ? with constantly evolving satellites, systems, signals, models, and data analysis methodology ? is a scientific challenge. This session solicits presentations on scientific applications enabled by IGS products and new science enabled by improvements to quality and breadth of GNSS products." ---------------------------------------------------------------------- -- ---------------------------------------------------------------------- Rolf Dach Astronomical Institute, University of Bern dach at aiub.unibe.ch Sidlerstrasse 5, CH-3012 Bern, Switzerland http://www.aiub.unibe.ch/ Tel: +41 31 684 8593 ftp://ftp.aiub.unibe.ch/ ---------------------------------------------------------------------- From arturo.villiger at aiub.unibe.ch Tue Jul 26 14:58:06 2022 From: arturo.villiger at aiub.unibe.ch (Arturo Villiger) Date: Tue, 26 Jul 2022 16:58:06 +0200 Subject: [IGSMAIL-8238] Upcoming switch to IGS20/igs20.atx and repro3 standards Message-ID: <8f636901-2e7e-fe99-29aa-00413fbfbd06@aiub.unibe.ch> Dear colleagues, The IGS will soon adopt a new reference frame, called IGS20, as the basis of its products. IGS20 is closely related to ITRF2020, released in April 2022. An updated set of satellite and ground antenna calibrations, igs20.atx, will also become effective at the same time and should be used together with IGS20. The IGS intends to switch from IGb14/igs14.atx to IGS20/igs20.atx starting with the products of GPS week 2230 (2 October 2022). The following files are already available for download at ftp://igs-rf.ign.fr/pub/IGS20: - IGS20.snx.gz????????? : IGS20 SINEX file (gzip compressed) - IGS20.ssc???????????? : IGS20 SINEX file without covariance matrix - psd_IGS20.snx???????? : post-seismic deformation models to be used with IGS20 - soln_IGS20.snx??????? : discontinuity list to be used with IGS20 - ITRF2020_to_IGS20.txt : position offsets applied to the ITRF2020 coordinates ????????????????????????? of IGS20 stations affected by ground antenna ????????????????????????? calibration updates from igsR3.atx to igs20.atx A first release of igs20.atx can be found at: http://ftp.aiub.unibe.ch/awg/igs20.atx.gz while future updates will be available at: https://files.igs.org/pub/station/general/igs20.atx At the same time as the switch to IGS20/igs20.atx, the IGS will also adopt for its operational products the same conventions and models as used in its third reprocessing campaign (repro3; see http://acc.igs.org/repro3/repro3.html). This includes in particular: - the processing of Galileo observations, in addition to GPS and GLONASS, by a ? number of IGS Analysis Centers, - the adoption of the new IERS secular pole model, - the rotation of phase center corrections to the actual orientations of ? antennas not oriented North, - the adoption of ***NEW LONG FILE NAMES FOR THE IGS PRODUCTS*** ? (see http://acc.igs.org/repro3/Long_Product_Filenames_v1.0.pdf). Details on the definition and use of IGS20 and igs20.atx, as well as on the main expected impacts of the switch to IGS20/igs20.atx and the repro3 standards on user results, can be found below. Note that test products based on IGS20/igs20.atx and the repro3 standards will be generated for a 2-month period before the switch (GPS weeks 2222 - 2229; 7 August - 1 October 2022) in parallel with the official IGb14/igs14.atx-based products. These test products will be available at: ftp://igs-rf.ign.fr/pub/igs20_tests Also note that a new version of the IGS cumulative solution, consistent with IGS20/igs20.atx and the repro3 standards, will be released with the products of GPS week 2230. It will initially be based on the IGS repro3 daily combined SINEX solutions of years 1994-2020. The weekly updates of the IGS cumulative solution will then halt for a few months, while the repro3 product series will be extended until 1 October 2022. It is expected that the weekly updates of the IGS cumulative solution resume in December, based on a complete up-to-date series of solutions compliant with the repro3 standards. For any question, please contact: - paul.rebischung at ign.fr for the reference frame aspects, - arturo.villiger at aiub.unibe.ch for the antenna calibration aspects. Best regards, Paul Rebischung, Arturo Villiger, Salim Masoumi, Tom Herring * Antenna calibration updates ? - Ground antenna calibrations: ????? Regarding ground antenna calibrations, igs20.atx is a minor update to the ????? ANTEX file used in repro3, igsR3.atx, which is itself a major update to ????? igs14.atx. ????? From igs14.atx to igsR3.atx, 37 legacy phase center correction patterns ????? covering the L1 and L2 frequencies only were replaced by new multi- ????? frequency patterns provided by Geo++ (36) and the University of Bonn (1). ????? From igsR3.atx to igs20.atx, 15 multi-frequency patterns provided by Geo++ ????? were further introduced. Besides, 2 type-mean multi-frequency patterns ????? already present in igsR3.atx were updated with the results of recent ????? individual calibrations. ????? Details on all these updates can be found in the header of igs20.atx. ? - Satellite antenna calibrations: ????? The radial phase center offsets (z-PCOs) of the GPS, GLONASS and Galileo ????? satellites have been updated in igs20.atx to become consistent with the ????? ITRF2020 scale. The new values were obtained from time series of z-PCO ????? estimates derived from the daily repro3 solutions of 9 Analysis Centers. ????? A single common correction was estimated and applied to the calibrated ????? z-PCOs of all Galileo satellites (except E102) provided by GSC. Another ????? single common correction was estimated and applied to the calibrated ????? z-PCOs of all GPS Block III satellites provided by Lockheed-Martin. ????? Satellite-specific z-PCOs were estimated for all other satellites. ????? Note that the terrestrial scale implied by the GPS, GLONASS and Galileo ????? satellite z-PCOs in igs20.atx matches the ITRF2020 scale at epoch 2015.0, ????? but departs from the ITRF2020 scale at a rate of about +0.1 mm/yr. * IGS20 reference frame definition and use ? - Station selection: ????? IGS20 is a subset of 332 stable, well-performing IGS stations from ????? ITRF2020. Station stabilities were assessed from the ITRF2020 results ????? (WRMS of residual time series, formal errors of ITRF2020 coordinates ????? propagated over expected lifetime of IGS20). Compared to IGb14, IGS20 ????? contains 98 new stations, mostly in previously sparsely covered areas. ????? On the other hand, 25 previous IGb14 stations were not selected in IGS20. ? - Coordinate corrections due to ground antenna calibration updates: ????? While ITRF2020 station coordinates are consistent with the set of ground ????? antenna calibrations used in repro3 (igsR3.atx), the IGS20 station ????? coordinates were made consistent, when needed, with the updated igs20.atx ????? antenna calibrations. For that purpose, the impact of the antenna ????? calibration updates on the positions of the affected IGS20 stations were ????? assessed by four IGS Analysis Centers (ACs) by means of differential PPP ????? analyses. Weighted averages of the AC position offset estimates were then ????? applied to the ITRF2020 coordinates of the affected IGS20 stations. The AC ????? position offset estimates and their weighted averages can be found at: ??????? ftp://igs-rf.ign.fr/pub/IGS20/ITRF2020_to_IGS20.txt ? - Transformation parameters: ????? Although some station coordinates differ between ITRF2020 and IGS20 due to ????? the ground antenna calibration updates from igsR3.atx to igs20.atx, both ????? frames share the same underlying origin, scale and orientation. The ????? transformation parameters between ITRF2020 and IGS20 are thus zero. The ????? transformation parameters between ITRF2020/IGS20 and past ITRF ????? realizations can be found at: https://itrf.ign.fr/docs/solutions/itrf2020/Transfo-ITRF2020_TRFs.txt ? - Discontinuities: ????? IGS20 station coordinates are generally represented by piecewise linear ????? functions, i.e., several position+velocity sets valid over successive time ????? intervals. Each set is denoted by a solution number (soln) whose validity ????? period is given in: ??????? ftp://igs-rf.ign.fr/pub/IGS20/soln_IGS20.snx ????? The discontinuity list in soln_IGS20.snx is based on the ITRF2020 ????? discontinuity list but also includes recent discontinuities and will be ????? continuously updated as new breaks occur. Because IGS20 does not contain ????? coordinates for solns starting after 31 December 2020 (end of ITRF2020 ????? input data), stations affected by such recent discontinuities cannot be ????? used as reference frame stations anymore. ? - Post-seismic deformation models: ????? Like in ITRF2020, the reference coordinates of some IGS20 stations include ????? post-seismic deformation models in the form of exponential and/or ????? logarithmic functions. These models are given in: ??????? ftp://igs-rf.ign.fr/pub/IGS20/psd_IGS20.snx ????? Details on their application can be found at: https://itrf.ign.fr/ftp/pub/itrf/itrf2020/ITRF2020-PSD-model-eqs-IGN.pdf ????? The IGS20 positions+velocities of the affected stations cannot be used ????? without the post-seismic deformation models. ? - Seasonal terms: ????? While coefficients of annual and semi-annual station displacements were ????? provided with ITRF2020, it was agreed among IGS ACs not to implement these ????? seasonal terms for the time being. IGS20 is thus provided without seasonal ????? terms. Users wishing to experiment with the ITRF2020 seasonal terms may ????? nevertheless add them to the IGS20 piecewise linear coordinates + post- ????? seismic deformation models. ? - IGS20 core network: ????? For the purpose of aligning global GNSS solutions to IGS20, a well- ????? distributed sub-network of IGS20 stations, called IGS20 core network, was ????? designed. It is composed of 55 clusters of stations (i.e., 55 primary ????? stations, each with possible substitutes) selected to ensure a homogeneous ????? global distribution and the best possible temporal stability of the core ????? network. The list of IGS20 core stations can be found at: ??????? ftp://igs-rf.ign.fr/pub/IGS20/IGS20_core.txt * Impact on user results ? - Reference frame change: ????? The alignment of the IGS products to IGS20 instead of IGb14 will induce ????? small global effects due to the reference frame change from ITRF2014 to ????? ITRF2020. The corresponding transformation parameters can be found at: https://itrf.ign.fr/docs/solutions/itrf2020/Transfo-ITRF2020_TRFs.txt ? - Ground antenna calibration updates: ????? The ground antenna calibration updates from igs14.atx to igs20.atx will ????? cause additional apparent position changes for many stations. This effect ????? will mainly be antenna-type-dependent, but will also depend on the station ????? locations. The apparent position changes can be expected to reach up to ????? several mm in horizontal; ~1 cm in vertical. ? - New IERS secular pole model: ????? While current IGS operational products make use of the mean pole model ????? from the original IERS Conventions, the new IERS secular pole model was ????? adopted in repro3 and will be adopted in the IGS operational products ????? after GPS week 2230. This model change induces an apparent, time-variable, ????? degree-2, order-1 deformation pattern of the terrestrial frame, whose ????? amplitude is relatively small until ~2010, but then increases linearly. At ????? the time of the switch to IGS20/igs20.atx and the repro3 standards, ????? apparent station position changes of up to ~4 mm in vertical; ~1 mm in ????? horizontal thus have to be expected. ? - PCO/PCV rotations for antennas not oriented North: ????? Although certain ground GNSS antennas are not oriented North, the IGS ????? practice until repro3 had been to ignore these mis-orientations and use ????? the phase center corrections from the IGS ANTEX files as if all antennas ????? were oriented North. In repro3 however, the phase center corrections have ????? been rotated when necessary to match the actual antenna orientations ????? reported in the site logs. The same practice will be adopted for the IGS ????? operational products after GPS week 2230. These PCO/PCV rotations have ????? impacts of up to a few cm in horizontal / a few mm in vertical on the ????? estimated positions of the affected stations. Antenna orientations, ????? extracted from the site logs, will be reported in an extra column in the ????? SITE/ANTENNA blocks of the IGS SINEX files. ? Other minor impacts can be expected from the inclusion of Galileo observations ? in the analyses of several ACs, as well as from the adoption of a certain ? number of models used in repro3, including: ? - latest-generation ocean tide loading models, ? - refined solar radiation pressure models, ? - the sub-daily EOP tide model from Desai & Sibois (2016; ??? https://doi.org/10.1002/2016JB013125), ? - time-variable gravity models.

These products are consistent with the SINEX solutions prefixed "IGS1R03FIN", and are aligned to the IGSR3 reference frame, as described in [IGSMAIL-8026], [IGSMAIL-8044], and https://igs.org/acc/reprocessing/#repro3. While the orbit combinations were performed by the IGS Analysis Centre Coordinator (IGS ACC) at Geoscience Australia, the clock and bias combinations were performed at Wuhan University led by Professor Jianghui Geng, who is currently the IGS PPP-AR Working Group Chair. Also, the reference attitudes were computed by Dr. Sebastian Strasser from Graz University of Technology. I would like to thank both for their huge efforts in this campaign. I would also like to thank Dr. Simon Banville, former chair of the IGS PPP-AR Working Group, who provided a lot of insightful advice and analyses to validate the products. I would also like to take this opportunity to thank all the IGS Analysis Centres for their high-quality contributions to the Repro3 campaign and their ongoing efforts. Details of the contributing IGS Analysis Centres are available in the IGS Technical Report 2021: Chapter 2: Analysis Centers: Analysis Center Coordinator: Table 5. The report also contains brief information about the combination procedures, which were also presented at Tour de l'IGS: 1st Stop: Repro3. The available products, and some of the new features of the products and combination strategy since Repro2 are listed below. For any further information, please feel free to contact acc at igs.org.

Just as the changes made to the style of the traditional SINEX summary files as indicated in [IGSMAIL-8026], I have made changes to the style of the summary files, as well as the addition of the daily orbit combination summaries, and the addition of the summaries in machine-readable JSON format. SOME NEW FEATURES OF THE COMBINED PRODUCTS SINCE REPRO2 --------------------------------------------------- * Repro3 combined products include GPS, GALILEO and GLONASS information. While GPS information starts from 1994-01-02, the GLONASS information starts from 2002-01-01, and the GALILEO starts from 2013-01-01. * Since the start of the year 2000, the "integer" clock combinations and the phase biases allow for PPP with ambiguity resolution. The clocks prior to the year 2000 were performed similar to legacy clock combination since no bias combination was performed prior to 2000 due to lack of AC bias solutions. COMBINATION STRATEGY ------------------- * The orbit combinations were performed by a newly developed combination software by the IGS ACC at Geoscience Australia. The new software is, however, written based on the same robust weighted average algorithm as the IGS ACC legacy software, with minor differences to allow for the multi-GNSS combinations, with the main difference being in weighting of the ACs: while the legacy GPS-only combinations use an AC-specific weighting for doing the combinations, the Repro3 orbit combinations are weighted based on AC and satellite, meaning that each AC may receive a different weight for each satellite. In the orbit comparisons and PPP validations, this proved to have insignificant impact on the results when compared to the legacy combinations, but was found useful to isolate the impact of "badly behaved" satellites on the combinations. * The satellite attitudes were calculated using the GROOPS software developed at Graz University of Technology, following the algorithms described here. * The clock and bias combinations were performed by the PRIDE ckcom software developed at Wuhan University. Some of the main features of the Repro3 clock combinations and differences compared to the IGS ACC legacy clock combinations are as below: * For the Repro3 and using the ckcom clock combination software, the phase biases are combined in conjunction with the clocks, which combines them into clocks with integer characteristics. This allows for the use of the clocks and biases for PPP with ambiguity resolution. This is a new feature for the IGS combined clocks. * As an improvement compared to the legacy clock combinations, the Repro3 clock combinations implement the satellite-PCO and attitude corrections to the AC solutions, which improves the clock consistencies among ACs and the accuracy of the combined clocks. * A set of common satellites among all ACs are selected which are present at all epochs, and the alignment of the clock datum is then performed epoch by epoch. * As with the previous Repro2, the combined clocks are aligned to GPST by fitting a linear model to the GPS broadcast ephemeris. The clocks are not re-aligned to the IGST; therefore, the combined clocks will have sizable day boundary discontinuities.

After this date, the listed receivers will continue to operate (i.e. track and record satellite signals), but the data will not be usable for any application requiring high precision and reliable positioning. The reason for this is an outdated base GPS time that will cause incorrect measurement data. By September 2022, these receivers will have been phased out for over 15 years. There will be no new ME2 firmware released to extend their operating life. Receiver Type Phase-out year GX1210 2007 GX1220 2007 GX1230 2007 ATX1230 2007 ATX900 2007 GRX1200 Classic 2007 GRX1200 Lite 2007 GRX1200 Pro 2007 GRX1200 receivers using a newer generation of measurement engine, e.g. ME3/ME3GG, ME4, OEM7, etc., are not affected by this and will continue to operate as normal. There's probably only one IGS station affected: BRFT00BRA. The station operator is informed, data submission will be disabled. Best regards, Markus M.Eng.

The delay was caused by a limitation in the number of station clock entries in the combination software. This issue is resolved now, and the IGS combined products were generated and deposited to the global data centres. Apologies for any inconvenience this may have caused.

The decision to postpone the switch was made following the feedback received from users and consultation with the IGS Analysis Centres, and will allow an additional time to prepare for the switch. Consequently, the test products based on IGS20/igs20.atx and the repro3 standards will be available for an extended period before the switch (GPS weeks 2222 - 2237; 7 August - 26 November 2022). Please note the following: 1) As previously indicated, the switch to the new long file names will occur at the same time as the transition to the IGS20/igs20.atx; 2) All IGS products, including final, rapid and ultra-rapid products, will be transitioned to IGS20/igs20.atx and long filenames; 3) Test products (for IGS final product line) have already started to become available in ftp://igs-rf.ign.fr/pub/igs20_tests/${wwww} and https://cddis.nasa.gov/archive/gnss/products/${wwww}/igs20/ where ${wwww} refers to GPS week. Please note that the 4th character in the long file names relates to the version/solution identifier (http://acc.igs.org/repro3/Long_Product_Filenames_v1.0.pdf). Generally for the IGS products, a resubmission of a product will have a higher version identifier in its file name; therefore, it is advised to always use the highest available version of any of the files, unless specifically advised otherwise; 4) Starting soon and before the date of final switch, the test products will be also available for rapid and ultra-rapid products. This will allow users to adapt their software for the new rapid and ultra-rapid products as well. Details of the location of these products will be advised accordingly. For further details regarding the transition, please refer to [IGSMAIL-8238], and feel free to contact: * salim.masoumi at ga.gov.au for questions related to the orbit/clock products, * paul.rebischung at ign.fr for questions related to the SINEX products or the reference frame, * arturo.villiger at aiub.unibe.ch for questions related to antenna calibrations.

This hybrid event will be taking place in Chicago, Illinois, USA and online everywhere on the 11th of December 2022 from 15:00-18:00 UTC. The AM/WG Meeting is open to all IGS Associate Members, Governing Board Members, and Former Governing Board Members, as well observers who would like to learn more about the IGS. Its intention is to be a forum for our Associate Members and friends to gather in between workshops to discuss ideas, learn about the IGS and its Working Groups and Pilot Projects. This session will provide an opportunity for the working group and pilot project chairs to update both governing board members and associate members on progress / issues resulting from the most recent 2022 virtual workshop recommendations and virtual Tour de l?IGS. It will also provide a forum for discussion about how to move forward with working group/pilot project activities as we head towards the 2024 IGS Bern Workshop (1-5 July 2024). The presentations will be short (5 minutes each) with 5 minutes for discussion after each. Participants who are new to the IGS, or are interested in joining an IGS Working Group/Pilot project are especially welcome. Registration and additional event information will be sent out later this month. In the meantime, please save the date for the event here: https://igs.org/event/5th-am-meeting/.

The focus of the research activities will be in the field of GNSS DATA ANALYSIS. The AIUB hosts the Center for Orbit Determination in Europe (CODE), one of the leading analysis centers of the International GNSS Service (IGS). An important part of the position will be devoted to the continuous improvement of the processing system, which is required to guarantee the operational activities with high reliability. The permanent development and improvement of the Bernese GNSS Software package, to also guarantee the high quality standards of the CODE products according to the latest scientific standards in the future, will be another core task of this position. Despite these rather technical tasks, also scientific research will be possible. The research topic shall support the CODE activities at AIUB which covers the wide range from global GNSS solutions up to the combination of GNSS with other space geodetic techniques on observation level. More details may be defined depending on the interest and the experience of the candidate. The complete position description is available at http://www.bernese.unibe.ch/Stellen/stelle2211.pdf Please circulate this information within your institution.

To estimate the DCB the GFZ rapid ionosphere product are introduced (Brack, A., M?nnel, B., Wickert, J., Schuh, H. (2021): Operational Multi?GNSS Global Ionosphere Maps at GFZ Derived from Uncombined Code and Phase Observations. - Radio Science.). The observations for the POD are taken for the DCB estimation using GFZ EPOS8 software, which make more consistent solution with our POD products. 2) in GBM0MGXRAP_20223210000_01D_01D_OSB.BIA.gz The OSB are now converted from UPD and the new DCB product. In the updated DCB&OSB products the PCO/PCV corrections are applied for the satellite and station. We follow the IGS conventional, intoducing ? APC_MODEL IGS14_2188 ? keyword? in the BIAS/DESCRIPTION block. Please feel free to contact me if you have any question about these products.

All IGS Analysis Centers have been required to apply the antenna phase center offset corrections to those geometry-free combination observables during the transition to ITRF2020. Similarly, users of IGS products will need to adopt this new convention as well to ensure consistency and achieve the best performance in ambiguity resolution. As the IGS has decided to transition to ITRF2020 and authorize the igs20.atx at the end of this November, users of IGS products need to be reminded of the following change on the Bias-SINEX format: A new keyword "APC_MODEL" will be added to the section ?BIAS/DESCRIPTION? in the format of "APC_MODEL igs20_WWWW.atx" when APCs are considered for geometry-free biases.

We owe you all a huge thanks for making the session popular over the years via your active participation. We have now added a few more topic/directions to include some of the upcoming research areas at the interface of Geodesy and Climate research. We invite you to consider submitting your latest and exciting research work to the Geodesy for Climate Session in EGU 2023. Please feel free to forward it to your colleagues and to other relevant mailing lists. Here is a short description of the session: G3.1 invites innovative Earth system and climate studies employing geodetic observations and methods. Modern geodetic observing systems have been instrumental in studying a wide range of changes in the Earth?s solid and fluid layers at various spatiotemporal scales. These changes are related to surface processes such as glacial isostatic adjustment, the terrestrial water cycle, ocean dynamics and ice-mass balance, which are primarily due to changes in the climate. To understand the Earth system response to natural climate variability and anthropogenic climate change, different time spans of observations need to be cross-compared and combined with several other datasets and model outputs. Geodetic observables are also often compared with geophysical models, which helps in explaining observations, evaluating simulations, and finally merging measurements and numerical models via data assimilation. We look forward to contributions that: 1. Utilize geodetic data from diverse geodetic satellites including altimetry, gravimetry (CHAMP, GRACE, GOCE and GRACE-FO), navigation satellite systems (GNSS and DORIS) or remote sensing techniques that are based on both passive (i.e., optical and hyperspectral) and active (i.e., SAR) instruments. 2. Cover a wide variety of applications of geodetic measurements and their combination to observe and model Earth system signals in hydrological, ocean, atmospheric, climate and cryospheric sciences. 3. Show a new approach or method for separating and interpreting the variety of geophysical signals in our Earth system and combining various observations to improve spatiotemporal resolution of Earth observation products. 4. Work on simulations of future satellite mission (such as SWOT and GRACE-2) that may advance climate sciences. 5. Work towards any of the goals of the Inter-Commission Committee on "Geodesy for Climate Research" (ICCC) of the International Association of Geodesy (IAG). We are committed to promoting gender balance and ECS in our session. With author consent, highlights from this session will be tweeted with a dedicated hashtag during the conference in order to increase the impact of the session. The deadline for submitting your abstract is 10th of January 2023. There is some travel support available for Early career researchers and senior researchers from low to middle income countries. For those looking for travel support, the abstract submission deadline is 01 Dec 2022. Best Wishes and looking forward to your contributions. -Bramha -------------------------------------------------------------------------------------------------------------------------------------------- Dr.-Ing.

As announced in [ https://lists.igs.org/pipermail/igsmail/2022/008234.html, | [IGSMAIL-8238] ] , the weekly updates of the IGS cumulative solution will then halt for a few months, while the repro3 product series is extended up to GPS week 2237. I t is now expected that updates of the IGS cumulative solution resume in February 2023, based on a complete up-to-date series of solutions compliant with IGS20/igs20.atx and the repro3 standards. Meanwhile, a first release of the "new" IGS cumulative solution, compliant with IGS20/igs20.atx and the repro3 standards, can be found at ftp://igs-rf.ign.fr/pub/igs20_tests , where the following files are available for download: * IGS0OPSSNX_1994002_2020366_00U_SOL.SNX.gz : Cumulative SINEX solution (3.6 GB) * IGS0OPSSNX_1994002_2020366_00U_CRD.SNX.gz : Cumulative SINEX solution without covariance matrix * soln.snx : Associated discontinuity list * psd_IGS.snx : Associated post-seismic deformation models * igsR3_to_igs20_offsets.txt : Station position offsets applied to input daily repro3 SINEX solutions in order to account for "igsR3.atx -> igs20.atx" ground antenna calibration updates This first release is based on the repro3 product series currently available, i.e., on data from January 2, 1994 till December 31, 2020. I would also like to take the opportunity of this announcement to poll users of the IGS cumulative SINEX solution about its update rate. It has historically been updated at a weekly rate, but every single weekly update actually has little impact on such a long-term solution, and it seems to me that less frequent updates (e.g., every month or every 2 months) should fit most usages. Less frequent updates would also allow us (providers of the solution) to improve our analysis of station position time series (in particular offset detection), hence the quality of the cumulative solution. My questions to users of the IGS cumulative SINEX solution are therefore the following: Are there usages which really require weekly updates of that solution? Otherwise, which update rate would satisfy your needs? Please let me know your answers by the end of January.

We would like to draw your attention to the session G.2.2 Terrestrial Reference Frame: data analysis, evaluation and applications [1] and encourage you to join us and submit an abstract to the session ! Note that the ABSTRACT SUBMISSION DEADLINE IS TUESDAY, 10 JANUARY 2023, 13:00 CET. Best regards, Kristel Chanard On behalf of the G.2.2 conveners, Claudio Abbondanza, Mathis Blo?feld et Susanne Glaser. ---------- G.2.2 Terrestrial Reference Frame: data analysis, evaluation and applications [2] The Terrestrial Reference Frame (TRF) is critical for monitoring the Earth's rotation in space, as well as for many geoscientific applications that need absolute positioning and exact orbit determination of near-Earth artificial satellites. Its new realization, the ITRF2020 has been released based on the combination of DORIS, GNSS, SLR, and VLBI station coordinate time series provided by the IAG/IERS Technique Services. The objective of this session is to bring together contributions from individual Technique Services, space geodetic data analysts, ITRS combination centres and all ITRF users, with a broad range of applications from geosciences to society, to discuss the results and scientific applications of ITRF2020 and other realizations. The assessment of observed non-linear, and particularly periodic, station motions through space geodetic techniques by comparison with physics-based deformation models is of particular interest. Moreover, contributions to geocenter motion determination are encouraged. Finally, contributions that focus on identifying and mitigating technique-related systematic errors as well as different combination strategies, e.g., space and tropospheric ties are encouraged because they may potentially enhance future ITRF solutions. ---------- Links: ------ [1] https://meetingorganizer.copernicus.org/EGU23/session/45855 [2] https://meetingorganizer.copernicus.org/EGU23/session/45855 -------------- next part -------------- An HTML attachment was scrubbed...

The EGU23 aims to bring together geoscientists from all over the world to one meeting covering all disciplines of the Earth, planetary, and space sciences. G2.1 session description: Precise orbit determination is of central importance for many applications of geodesy and earth science. The challenge is to determine satellite orbits in an absolute sense at the centimeter or even sub-centimeter level, and at the millimeter or even sub-millimeter level in a relative sense. Four constellations of GNSS satellites are available and numerous position-critical missions (e.g. altimetry, gravity, SAR and SLR missions) are currently in orbit. Altogether, outstanding data are available offering new opportunities to push orbit determination to the limit and to explore new applications. This session aims to make accessible the technical challenges of orbit determination and modelling to the wider community and to quantify the nature of the impact of dynamics errors on the various applications. Contributions are solicited from, but not limited to, the following areas: (1) precise orbit determination and validation; (2) satellite surface force modelling; (3) advances in modelling atmospheric density and in atmospheric gravity; (4) advances in modelling earth radiation fluxes and their interaction with space vehicles; (5) analysis of changes in geodetic parameters/earth models resulting from improved force modelling/orbit determination methods; (6) improvements in observable modelling for all tracking systems, e.g. SLR, DORIS, GNSS and their impact on orbit determination; (7) advances in combining the different tracking systems for orbit determination; (8) the impact of improved clock modelling methods/space clocks on precise orbit determination; (9) advances in modelling satellite attitude. Please consider submitting an abstract to this dedicated orbit session. The deadline for abstract submission is January 10, 2023 at 13:00 CET. We are looking forward to your contribution.

A precisely defined and accurate reference frame improves our understanding of the Earth?s system and its time variations, including Earth?s variable rotation and gravity field, sea level changes and their global environmental impact, tectonic plate motion, glacial isostatic adjustment, geocenter motion, deformation due to the earthquake cycle, terrestrial water storage, ice-sheet melting, ocean and atmospheric loading, and volcanism. ?An accurate reference frame is also needed to position GNSS, SLR and DORIS satellites, and any Earth observation satellite or aircraft with geodetic sensors such as those used for ocean and ice-sheet altimetry, InSAR, gravimetry, and LiDAR. Furthermore, self-consistency is required to connect the terrestrial frame, celestial frame, and Earth rotation to realize the inherent stability in orientation and scale provided by VLBI quasar observations. Co-location, whether it be on the ground or in space as planned with VLBI transmitters on satellites, is essential to tie the various space geodetic techniques together into one consistent global reference system to be used for Earth monitoring. For this symposium, we solicit presentations dealing with theoretical aspects of reference systems and the practical realization of the celestial, global and regional terrestrial reference frames, as well as their various applications like those mentioned above, and beyond. The contributing role of space geodetic techniques in the realization of the origin and scale of global frames through new and improved modeling of their systematic errors and novel exploitations of LEO satellites is also a topic of great interest for this symposium. We also solicit presentations on new and emerging technologies applicable to the future of reference frames such as inter-satellite links, as well as relativistic and quantum geodetic sensors.???? -- Dr.-Ing.
