From jhgeng1982 at gmail.com Tue Jan 2 04:07:24 2024 From: jhgeng1982 at gmail.com (Jianghui Geng) Date: Tue, 2 Jan 2024 12:07:24 +0800 Subject: [IGSMAIL-8409] All-frequency phase bias products and PRIDE PPP-AR Ver. 3.0 for day-boundary continuities Message-ID: <0B242E98-846C-4F20-8695-0EFAB23E2B66@gmail.com> Dear all, Happy new year! We are pleased to announce that ALL-frequency rapid code/phase bias products (i.e., WUM0MGXRAP) for GPS, Galileo, BDS-2 and BDS-3 have been released at IGN (since week 2290 on ftp://igs.ign.fr/pub/igs/products/mgex/ ) and Wuhan (since day 001 of 2023 on ftp://igs.gnsswhu.cn/pub/whu/phasebias). The latency is less than 18 hours normally (Note: dual-frequency WUM0MGXRAP product is faster at a latency of about 11 hours, but updated only on Wuhan FTP). CDDIS is also updating them, but at a longer latency of up to a few weeks at the moment (https://cddis.nasa.gov/archive/gps/products/). ?All-frequency? means to enable PPP ambiguity resolution (PPP-AR) at any frequency choices and observable combinations (e.g., even GPS L1/L5 PPP-AR in the case of inter-frequency time-variable clock biases). This WUM0MGXRAP product contains: a 30-s satellite clock file with the 24:00 epoch especially, fully aligned with the IGS legacy clock, but with integer nature; a bias-SINEX file with daily code/phase OSBs for all frequency bands except for the 15-min GPS Block IIF L5 and BDS-2 B2I phase biases; as well as the 5-min orbit, 30-s satellite attitude quaternion and daily ERP files. All antenna phase centers have been applied to the bias generation (i.e., APC_MODEL). Satellite clocks plus code/phase biases have been aligned precisely across days for all frequencies on account of orbit discontinuities. This means that day-boundary discontinuities for GPS, Galileo, BDS-2 and BDS-3 products have been minimized to the smallest since 2023 thanks to our keeping integer continuity of undifferenced ambiguities for all frequencies from day to day. This would benefit kinematic positioning and time/frequency transfer across days, no matter which frequency choices. Users would not need to calibrate day-boundary discontinuities anymore at their own side. Simultaneously, we have upgraded the open-source software PRIDE PPP-AR to version 3.0 at https://github.com/PrideLab/PRIDE-PPPAR. This version supports the all-frequency PPP-AR functionality for any two eligible frequency choices (e.g., GPS L1/L5, Galileo E1/E6, BDS-2 B1I/B2I, BDS-3 B1C/B2a, etc.). LEO kinematic orbit determination is also enabled for GRACE particularly. The positioning and orbit precisions are state-of-the-art compared to IGS and relevant official institutions. In addition, PRIDE PPP-AR results are expected to be free from any day-boundary discontinuities for kinematic positions and time transfer when multi-day processing of up to 108 days is enabled, especially when BDS-2 is excluded. Please do not hesitate to contact us (pride at whu.edu.cn ) if you encounter any problem with the WUM0MGXRAP product or the PRIDE PPP-AR software. This work is funded by National Science Foundation of China (No. 42025401) and under the auspices of IAG Sub-Commission 4.2 ?Multi-constellation and multi-frequency GNSS? and IGS Pilot Project PPP-AR (https://igs.org/wg/ppp-ar/#rapid).

So we can celebrate today the 30th anniversary of the IGS. A lot of things have been achieved within the IGS (see for instance the plot on the GPS orbit combinations: http://acc.igs.org/media/Gmt_sum_final_all_orb_smooth_ALL.gif); we have not just a final but meanwhile a rapid, ultra-rapid and even a real-time product line. We have made progress in the inclusion of more and more systems into our operational product lines. With the regular reprocessing efforts the IGS strongly contributes to the ITRF solutions and allows the user community a direct access via the PPP approach. I know that this list of achievements is quite incomplete but I should resist to make the mail too long by listing all achievements of the last 30 years. It is a good point to thank all people and their institutions supported the activities of the IGS in the past, present and in future for their contributions to the success story of this community. I had the pleasure to join many of the IGS workshops in the past and it was like a "come together event" of a big family in the scientific spirit of the "friendly competition". All contributions to the community are important to keep the IGS a successful organization also in the future. Often only the big contributions like the central bureau, the data and analysis centers are very visible but each station or active participation in a working group (most of them became product committees with the most recent revision of the Terms of References) is important as well. For the future I hope that we can continue our path of success with new groups and people getting involved (e.g., we are happy to welcome a new analysis center hosted by JAXA and GSI). This confirms that the IGS is still a field of interesting scientific work. We are seeking all the time for new people with new ideas to further develop the idea of the IGS and advance the quality of the products. In this sense I'm looking forward to our next in person meeting at the IGS Symposium and workshop planned for the week from July 1st to 5th, 2024 (https://igs.org/workshop/2024/) where we are going to celebrate the IGS for Three Decades of Service to Science and Society. I wish all the IGS contributors and friends of the IGS a good start into the new year 2024 -- the 31st year of the IGS.

The products can be found in CDDIS as below: 1) IGS combined multi-GNSS experimental orbits in SP3 format: https://cddis.nasa.gov/archive/gnss/products//IGS0DEM_ULT00_02D_05M_ORB.SP3.gz 2) Orbit combination summary files (new refreshed summary file format): https://cddis.nasa.gov/archive/gnss/products//IGS0DEMULT_00_02D_02D_SUM.SUM.gz 3) Orbit combination summary files in machine-friendly JSON format: https://cddis.nasa.gov/archive/gnss/products//IGS0DEMULT_00_02D_02D_SUM.JSON.gz where is GPS week, is the year, day of year, and hour of the starting epoch of the file (start of the observed period in the ultra-rapid orbits). At this demonstration phase, these products will become available about 20 minutes after the ultra-rapid operational products (approximately at 03:20, 09:20, 15:20, 21:20 UTC). It should be noted as the "DEM" Campaign/Project specification in the naming of the files suggests, these products are demonstration products and experimental only. Users are advised to continue using the operational products (IGS0OPS*) for their operational routines. The orbit combination algorithm of the demonstration products follows the methodology used for the IGS Repro3 campaign and described in a recently published paper Combination and SLR validation of IGS Repro3 orbits for ITRF2020. Since these products include the three constellations GPS, Galileo and GLONASS, the IGS GLONASS ultra-rapid orbits (igv* products) will stop soon. Further announcements will be made as to the exact date the igv* products will stop giving ample time for the users to switch over to the new experimental multi-GNSS products. The DEM summary files contain the comparison statistics for the IGV products so that users can assess the level of difference between the new and old GLONASS orbits, as well as the differences to the operational GPS orbits. Further developments and assessments of the multi-GNSS combinations are currently underway within the IGS ACC, IGS MGEX Pilot Project and the IGS multi-GNSS task force in order to progress further in achieving multi-GNSS combined products.

EGU24 session G2.3 Global Geodetic Observing System: The Reference for Earth System Monitoring Message-ID: <7873C0D0-E46D-427A-BB62-876FDFC92CDF@jpl.nasa.gov> Dear Colleagues, The EGU General Assembly 2024 will take place from 14?19 April in Vienna & Online, and there is one day left to submit abstracts! IGS is once again joining together with other IAG services and components to contribute to oral and poster sessions organized by GGOS at EGU: G2.3 ?Global Geodetic Observing System: The Reference for Earth System Monitoring?. High precision modern geodetic observations enable comprehensive monitoring of multiple spheres of the Earth. They record fingerprints of changes within the Earth System, providing crucial information to address major scientific issues, e.g., natural hazards, climate changes, global water cycles. Interpreting geodetic observations requires implementation of reference frames, analysis techniques and models with accuracy comparable to or exceeding the observations. Consequently, geodesy expanded its scope from just measuring geometry, gravity, and rotation of the Earth to understanding fingerprints recorded there and has become a key science to understand the Earth System for functioning and sustainability of our society. The Global Geodetic Observing System realizes the metrological basis for monitoring the Earth System. It is designed to unite individual geodetic observations and model them into one consistent frame with the highest precision available. We welcome contributions relevant to GGOS, particularly its scientific and social aspects, infrastructure, products, and activities of geodetic services. You can also find the session description at: https://meetingorganizer.copernicus.org/EGU24/session/49269 We encourage you to participate in it by submitting abstracts! The Call for Abstracts for EGU24 closes at 10 January, 13:00 CET. https://egu24.eu/programme/how_to_submit.html Best regards, The session conveners: Convener: Kosuke Heki | Co-conveners: Martin Sehnal, Allison Craddock, Esther Azcue -We apologize for multiple posting- -------------- next part -------------- An HTML attachment was scrubbed...

The extended Repro3 combined products generally follow the same combination methodology as those for the period 1994-2020 (see [IGSMAIL-8248] and https://igs.org/acc/reprocessing/#repro3.). The only exception is that, since only two Analysis Centres provided phase biases for this extended period, a robust combination of phase biases and integer clock combinations was not possible. Therefore, the combined clocks for this extended period consist of multi-GNSS legacy clocks with no combined bias products. Additionally, there have been a couple of name changes based on the latest IGS long product filename: clock summary files are now named *CLS.SUM as opposed to previously *CLS.CLS, and *EOP.JSON files are now called *ERP.JSON. These filename changes have been applied to the full Repro3 period. Similar to the full Repro3 period, the extended Repro3 combined products are consistent with the Repro3 terrestrial frame (SINEX) solutions and are based on the IGSR3/igsR3.atx frame as described in [IGSMAIL-8329]. The extended Repro3 orbit and clock combinations are available in the weekly sub-directories at https://cddis.nasa.gov/archive/gnss/products/repro3/ and will soon be available in other global data centres. The extended products are based on the contributions of 5 Analysis Centres: * COD (Centre for Orbit Determination in Europe) * GFZ (GeoForschungsZentrum) * GRG (Groupe de Recherche en G?od?sie Spatiale) * MIT (Massachusetts Institute of Technology) * NGS (National Geodetic Survey) I would like to thank the Analysis Centres who provided their contributions to the extended Repro3 series.

These OSBs are computed by fixing the real-time satellite orbits and clocks from SSRC00WHU0. Our OSB streams contain the 5-s code/phase biases (Ref: CoM) estimated every 5 minutes for the GPS L1/L2/L5, Galileo E1/E5a/E5b/E5/E6, BDS-2 B1I/B2I/B3I and BDS-3 B1I/B1C/B2a/B2b/B3I signals, and thus can enable all-frequency PPP ambiguity resolution. Conservatively, over 80% of GPS, Galileo and BDS-3 ambiguities can be resolved at a typical GNSS station, which depends on the global GNSS data stream quality. More details can refer to the following articles. This work is funded by National Science Foundation of China (No. 42025401) and under the auspices of IAG Sub-Commission 4.2 ?Multi-constellation and multi-frequency GNSS? and the IGS PPP-AR & RT WGs.

IGS Joint Trial Project? (JTP), established jointly with the GNSS providers in the frame of the International Committee on GNSS (ICG). The Objective of the IGMA JTP is the establishment of a trustworthy and comprehensive system for international monitoring and assessment based upon a harmonized calculation methodology. Background The International Committee on GNSS (ICG) established the International GNSS Monitoring and Assessment (IGMA) Task Force at the ICG-6 meeting in Tokyo in 2011, tasked to facilitate cooperation and information between providers and scientific organizations that engage in open service signal quality monitoring. The International GNSS Service (IGS) is playing a key role in producing precise GNSS products since its inception in 1994. It is active in coordinating the operation of a global multi-GNSS network and generating multi-GNSS products. The ICG recommended at the ICG-10 meeting in Boulder in 2015 that the IGMA Task Force and the IGS initiate a joint Trial Project to demonstrate a global GNSS Monitoring and Assessment capability, utilising existing resources and infrastructure and avoiding duplication. Participation from non-IGS analysis groups, networks, and data centres is invited to develop benchmarking between groups and to generate analysis products, cross-sharing between existing IGS functional streams and IGMA activities. Initially, a limited number of parameters is proposed for monitoring to demonstrate the monitoring service and exercise it operationally. This will be followed by a broader set of parameters to be monitored as the system approaches permanent operations. The IGS Monitoring Working Group has been established to install, operate, and further develop the GNSS Monitoring and Assessment Trial Project jointly with ICG?s IGMA Task Force, considering the Terms of Reference of the IGMA Task Force for the IGMA-IGS Joint Trial Project, utilising existing resources and infrastructure, and creating publicly available, useful data products. During the 64th IGS Governing Board Meeting, it was decided to restart the activities of the former IGS Monitoring Working Group in the form of a new Pilot Project, called IGS Monitoring Pilot Project. In the 65th IGS Governing Board Meeting, the IGS GB endorsed the updated ICG IGMA Terms of Reference (ToR) and agreed to issue a second Call for Participation for the IGS Monitoring Pilot Project. Organisational Aspects The IGS Monitoring Pilot Project shall, as already outline above, reuse the existing infrastructure of the IGS to the maximum extend. This Call for Participation is released to enlist the participation of the new IGS Monitoring Pilot Project and to solicit the participation of new institutions. GNSS Monitoring Pilot Project The GNSS Monitoring Pilot Project is responsible for establishing and managing the IGS GNSS Monitoring Infrastructure, aiming for providing an independent GNSS monitoring infrastructure and associated analysis capabilities. The IGS Monitoring Pilot Project further aims to contribute to the International GNSS Monitoring and Assessment (IGMA) ? IGS Joint Trial Project? (JTP) established jointly with the GNSS providers in the frame of the International Committee on GNSS. The IGS Monitoring Pilot Project chair represents the IGS Monitoring Pilot Project in the International Committee on GNSS (ICG) International GNSS Monitoring and Assessment (IGMA) Task Force. Active Membership Those, who wish to contribute actively to this Pilot Project can ask to being included as a Monitoring Analysis Centre (MAC) or as a member, contributing to the project and related tasks. E-mail Updates Those who wish to merely stay informed, access the website, and receive e-mail updates can simply sign up for our e-mail distribution list. Initial IGS Monitoring Pilot Project 2024 tasks plan: * Issue a 2CfP, inviting GNSS Provider Service Centers, IGS and MGEX ACs, IGS DCs, Networks, and other interested IGS and non-IGS groups to contribute to the IGS GNSS Monitoring Pilot Project * CfP deadline 15. March 2024 * First IGS Monitoring Pilot Project meeting, beginning of April 2024 (TBC) * Review of IGS Monitoring Pilot Project Charter by the end of May 2024 * Implementation of Pilot Project * IGS Monitoring Pilot Project chair to represent the Pilot Project in the ICG IGMA activities. Response to CfP This Call for Participation is released to enlist the participation of the new IGS Monitoring Pilot Project and to solicit the participation of new institutions. Interested organisations or individuals are asked to fill out the attached form and express their interest in participating in the Pilot Project by sending the filled form attached to this email to erik.schoenemann at esa.int by Friday, 15 March 2024.

The products that are concerned are JPL0OPSFIN and JPL0OPSRAP. The changes are scheduled to take effect starting on the 4th of March 2024 (DOY 064). It is imperative to note that the change is not retroactive - previously generated maps will remain unaffected. Key improvements include: * Enhanced Codebase: We have streamlined our codebase to fortify its resilience and expedite support. This involves a transition to exclusively Python (3.9x) and the migration to a version-controlled repository for improved management. Our backend map generation module was also made to seamlessly align with the underlying software - JPL-GIM (Martire et al., under review). * Refined RMS Maps: With this upgrade, RMS maps accompanying each IONEX file will now be based on uncertainties computed internally by the JPL-GIM software. This represents a departure from the previous approach, which utilised a singular value per solar-geomagnetic sector. * Expanded GNSS Station Coverage: We have augmented the number of GNSS stations factored into each map computation, and made future augmentations easier. At the time of upgrade, the average count will increase from 200 stations to 250+, thereby enhancing the accuracy and reliability of our outputs. * Time Alignment to UTC: To mitigate potential delays stemming from daylight savings time adjustments, our map generation process will now align with UTC instead of Pacific time, ensuring seamless and timely integration in other processes. These upgrades do not incur changes to the format of our products, and should therefore seamlessly integrate into your existing workflows. Please do not hesitate to reach out to us, should you require any further clarification or assistance.

POSITION DESCRIPTION The Scripps Institution of Oceanography at the University of California San Diego invites applications for a full-time Researcher position to be funded by extramural research grants and contracts in the area of Geodesy. We seek outstanding candidates with expertise in areas including marine and/or terrestrial geodesy, satellite geodesy, seafloor positioning, reference frames, processing and analysis of geodetic positions (e.g., GNSS, InSAR), modeling geophysical processes, time series analysis and data science (e.g., machine learning). The successful candidate will be distinguished by a deep understanding of geodetic methods and applications. The Researcher series at Scripps Oceanography parallels the Professor series in terms of research and service, but it carries no teaching requirements. Researchers receive eleven-month appointments with 25% salary support from institutional sources but are expected to establish an externally funded research program that provides the remainder of their salary support. Researchers at Scripps often obtain educator appointments as well and serve as graduate student and postdoc advisors. We seek motivated research geodesists to take advantage of new funding opportunities to expand the pool of geodesists in the U.S. through innovative research and mentoring students and postdocs and supporting a new geodesy track within the existing geophysical curriculum. The candidate's research program will complement and possibly overlap other research efforts at the Institute of Geophysics and Planetary Physics such as the Seafloor Geodesy Equipment Pool, the Scripps Orbit and Permanent Array Center (SOPAC), and the Satellite Geodesy group. Initial funding may be available from grants already awarded to these groups. We are interested in candidates who have demonstrated excellence in research and service, and who are committed toward building an equitable and diverse scholarly environment. A competitive record of publication, as well as evidence of the ability to conduct and fund an active research program consistent with the appointment level, is required. Candidates will be considered at the Assistant, Associate, or Full Researcher levels. The ranks of Associate and Full level are expected to have a record of securing extramural funding. Rank and salary will be consistent with the applicant's qualifications, experience, and University of California pay scales. Scripps Institution of Oceanography is a world-renowned center of solid Earth, planetary, oceanographic, biological, and atmospheric research committed to academic excellence and diversity within its student body, staff, and approximately 200 principal investigators ( https://scripps.ucsd.edu/diversity ). *School*: http://scripps.ucsd.edu QUALIFICATIONS *Basic qualifications* (required at time of application) Candidates are required to hold a Ph.D. in an area of Earth and Ocean Science, Physics, Engineering, or other related field, preferably with a record of geodetic-related research experience.

The majority of the resubmitted clocks do not have a significant impact on the positioning estimations, except for two of the Rapid clocks. Please see below the list of the resubmitted clocks and the impact on PPP solutions: IGS Rapid clocks of GPS week 2296, dow 4 (Year 2024, Day of Year 011) to GPS week 2299, dow 4 (Year 2024, Day of Year 032) were corrected for an issue with the alignment to IGRT and were republished. There has been no identified impact on PPP solutions. IGS Final clocks of GPS weeks 2295 to 2301 (Year 2023, Day of Year 365 to Year 2024, Day of Year 048) were not initially aligned to IGST, but were later replaced by the clocks that were re-aligned to IGST. There has been no identified impact on PPP solutions. IGS Rapid clocks of GPS week 2303, dow 5 (Year 2024, Day of Year 061) to GPS week 2305, dow 6 (Year 2024, Day of Year 076) were corrected for an issue with the alignment to IGSR and were republished. There has been no identified impact on PPP solutions for most of this period. The exception is the originally published Rapid clocks for GPS week 2305, dow 2 and 3 (year 2024, day of year 072 and 073) impacted the PPP solutions showing as a bias in the estimated positions. This was because for these two days, the clocks were incorrectly shifted by large values of about 400 micro-seconds, which could cause a bias in the position estimates. The re-published clocks are expected to result in accurate position estimates. The issues with the alignment of the Rapid and Final clocks to IGRT and IGST have been resolved and the products are being aligned to the IGS Timescale as usual. Apologies for any inconvenience the above issues may have caused.

These changes will better align our metadata with international geographic standards, such as ISO-3166, ensuring maximum shareability and interoperability, especially in the realm of machine-to-machine communications and machine learning applications, where there is a need to increase the machine readability of IGS metadata as it describes countries, areas, and geographical regions. The change also ensures that our site logs align with other IGS standards such as RINEX and GeodesyML. Governing Board Decision After careful consideration, the IGS Governing Board decided (in December 2021) to modify the term ?Country? to ?Country or Region? (also written ?Country/Region?) when talking about place names in the IGS network and community. This modification will be implemented in order to use vocabulary that is more inclusive to stations in international territories and regions, such as the Antarctic and Arctic. This also seeks to preserve and protect the IGS status as a politically neutral scientific organisation. As such, IGS Governing Board has sanctioned the utilisation of alphabetical three-character (Alpha-3) ISO-3166 country/region codes. An implementation plan has been devised and accepted. Furthermore, the plan has received approval from other international networks, such as APREF and EPN. The assignment of countries, regions, or areas to specific groupings is for technical interoperability and statistical convenience and does not imply any assumption regarding political or other affiliation of countries or territories by the International GNSS Service (IGS). The designations employed and the presentation of material on the IGS site do not imply the expression of any opinion whatsoever on the part of the IGS concerning the legal status of any country, territory, city, or area or of its authorities, or concerning the delimitation of its frontiers or boundaries. What will change Over the coming months the IGS Infrastructure Committee will implement the decisions made by the Governing Board through changes to the IGS site logs. The blank.log will be replaced with blank_v2.0.log and the instructions provided in sitelog_instr.txt will be modified and saved as sitelog_instr_v2.0.log. Furthermore, we will take this opportunity to fully adopt the 9-character station identifiers in both the filename and the metadata files themselves. For example, the filename pots_20240101.log will be changed to pots00deu_20240101.log. Changes to the blank.log The changes to the blank.log are highlighted in blue. XXXX Site Information Form (site log) XXXXMRCCC Site Information Form (site log v2.0) If Update: Previous Site Log : (ssss_ccyymmdd.log) Previous Site Log : (ssssmrccc_ccyymmdd.log) Four Character ID : (A4) Nine Character ID : (A9) Country : Country or Region : (A3) For the station POTS00DEU, the changes will look like this: POTS Site Information Form (site log) POTS00DEU Site Information Form (site log v2.0) If Update: Previous Site Log : pots_20230101.log Previous Site Log : pots00deu_20230101.log Four Character ID : POTS Nine Character ID : POTS00DEU Country : Germany Country or Region : DEU Timeline for changes The implementation of the updates will commence on June 5, 2024, utilising the updated site logs appearing in the existing /log_9char directory. Initially, only the active site logs will be modified, while the archived site logs will remain untouched. The changes are planned to be completed by the end of 2024. Following this, at a date still to be determined, we will remove the current /log folder, which contains the "old" version logs, and relocate the test directory from /log_9char to /log. It's important to note that the implementation timeline pertains specifically to metadata on the IGS servers. The actual implementation, such as folder structure, for other services like APREF and EPN, may differ. Please refer to their respective email correspondences for more details.

We would like to draw your attention to Session 2 "Building global GNSS-based reference frames" (see description below). Please consider submitting an abstract to this session at: [ https://www.conftool.com/igs2024/ | https://www.conftool.com/igs2024/ ] Best regards, The convener team: Paul Rebischung, Rolf Dach, Tom Herring, Salim Masoumi, Oliver Montenbruck, Arturo Villiger Session description By providing long, precise position time series for a dense global network of GNSS stations, as well as accurate polar motion time series, the IGS makes a fundamental contribution to the construction of the International Terrestrial Reference Frame (ITRF). GNSS station position time series, often derived from precise IGS ephemerides, also find wide usage in the study of diverse geophysical processes. Yet, despite the tremendous progress achieved in the analysis of GNSS data over the last decades, the IGS geodetic products remain affected by random and systematic errors that limit their contribution to the ITRF and geophysical interpretation. In this session, we seek contributions on any improvements to the analysis and modeling of GNSS data that could further augment the value of IGS products, including ephemerides and station position time series, but also global geodetic parameters (Earth rotation parameters, geocenter coordinates and terrestrial scale estimates). Topics may include, but are not limited to: * GNSS satellite orbit modeling (attitude, solar radiation pressure, other non-conservative forces, etc.); * characterization of GNSS satellite antennas (estimation / validation of phase center offsets, phase variations and group delays, impact on terrestrial scale); * characterization and improvement of ground GNSS antennas (comparison / validation of phase center offsets and variations, in-situ calibrations, multipath mitigation or modeling, etc.); * joint processing of legacy and new (BeiDou, QZSS, NavIC) navigation satellite systems; * joint processing of observations from ground- and space-based receivers; * joint processing of GNSS data with other space geodetic techniques; * improvements and aliasing assessment of background solid Earth, ocean and pole tide models; * use of non-linear a priori TRF components (e.g., ITRF2020 seasonal station motions); * statistical modeling of GNSS station position time series. -------------- next part -------------- An HTML attachment was scrubbed...

We regret to inform height stabilization system of METS00FIN has failed and cannot be repaired. The station become operational IGS station in 1992 and stabilization system served us 33 years keeping the antenna height stable on our 21 m height steel mast. Due this incident we decided to end operations of this GPS only station since it is not stable enough due to thermal expansion. ? METS00FIN is in the Mets?hovi Geodetic Research Station where it is collocated with VLBI, SLR, 2 superconducting gravimeters, absolute gravimeter, several SAR corner reflactors, and MET300FIN GNSS Station (GPS+GLO+GAL+SBAS). MET300FIN was installed in 2013 and is from now on the main GNSS instrument at Mets?hovi Geodetic Research Station. All instruments mentioned above are close to each other, founded on solid bedrock and under our attempts towards sub-millimeter local ties using terrestrial and GNSS measurements. Outside the observatory area are also METG00FIN GNSS station and Doris station.?? ? Data flow from METS00FIN will be shut down on June 25th, and site log will be then udpated to mark the station as decommissioned. If you know any parties are using METS00FIN for something, please inform them to switch to MET300FIN. ? ? Best regards Topi Rikkinen ?

Session description: Precise Orbit Determination (POD) is a discipline of Space Geodesy enabling Earth Science. POD is driven by the need for accurate geophysical products on global and regional scales, the goal to obtain a precise reference frame with a precision of 1mm in position and 0.1 mm/yr in velocity, especially in view of the upcoming co-location in space mission, Genesis, and the need for high accuracy POD products to support increasing real-time applications. POD requires and benefits from advances in force modelling (such as precise modelling of time-variable gravity, and non-conservative forces) as well as advances in measurement modelling for the space geodetic techniques used for POD (GNSS, SLR, DORIS, VLBI) and the combination thereof as many spacecraft are multi-technique POD satellites. This session solicits papers that highlight recent advances in this essential discipline of Space Geodesy for current and future satellite missions and their impact on the respective geophysical products. Please consider submitting an abstract to this dedicated orbit session. The deadline for abstract submission is Wednesday, 31 July at 23:59 p.m. ET/03:59 +1 GMT. We are looking forward to your contribution.

We are looking forward to your contribution by submitting an abstract to our session. Please note the Abstract submission deadline: Wednesday, 31 July 23:59 EDT/03:59 +1 GMT. For more information about the 2024 Fall Meeting, please consult: https://www.agu.org/annual-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) G018. 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, in the context of the ITRF2020 Updates are particularly welcome. Papers on the exploitation of past ITRF solutions and the latest 2020 solutions are also encouraged. -------------- next part -------------- An HTML attachment was scrubbed...

Often these data are assimilated into numerical models. In times of increased intensity and frequency of severe weather events due to climatic changes these data allow a better tracking or improved understanding of a tropospheric event. Similarly, GNSS signals are susceptible to changes in the ionosphere and can be employed for modelling or prediction of space weather. Moreover, advanced ionospheric modelling provides improvements of accuracy and integrity in the observations. This session is dedicated to highlighting advancements in geodetic observations, methods and assimilation, and their contributions to weather and space weather: low-cost and multi-instrument; observation processing and modelling, advanced products; multi-GNSS, GNSS-RO, GNSS-R, reflectometry; severe event studies; airborne, space borne, oceanic and moving platform observations; forecasting, assimilation, numerical models, tomography; high performance computing and machine learning. We look forward to receiving your abstracts and to meeting you in Washington D.C. in December.

In last several years, the solution was identified as ultra-rapid solution with 'ULT'. After kindly reminding by our colleagues, we notice that the 'NRT' identifier has been assigned to the solution with time latency between real-time and 6 hour in the document "GUIDELINES FOR LONG PRODUCT FILENAMES IN THE IGS V2.0". Hence, the solution type identifier has been transited from 'ULT' to 'NRT' since the 3rd hour of this Thursday (DOY 185, 2024). Moreover, the filename refers to the start point of the file content, i.e. the start of observed data, instead of the start of the prediction. We are sorry for the inconvenience caused by the transition, and apology for the late announcement. Besides the near real-time orbit, 300s clock, as well as Multi-GNSS dual-frequency OSB products with 1h latency, we also start to provide the hourly-updated 30s high-rate clock products, but the latency is about 1.5 hour. Hopefully, those products can meet the GNSS applications with low latency requirement, and can be download publicly via IGS data center at Wuhan (ftp://igs.gnsswhu.cn/pub/gps/products/mgex) or IGN (ftp://igs.ign.fr//pub/igs/products/mgex).

Best regards, Steven Nerem, Jade Morton, Benedikt Soja (G004 convener team) Session description: Artificial intelligence and machine learning have become important tools for understanding patterns and signals in large volumes of data, and so it is natural that these techniques are beginning to be applied to analyze geodetic data. This session seeks talks on a broad variety of applications of AI/ML in geodesy including earth surface, natural hazard and climate change monitoring. AI/ML is exceptionally suited for tackling challenges such as pattern classification, dynamic time series modeling, short-term forecasting, downscaling, and data fusion. The expanding volume of geodetic data, including highly-resolved GNSS time series, InSAR deformation maps, and satellite gravimetry and altimetry products, alongside enriched auxiliary data from advanced weather and environmental models, increasingly favors AI/ML methodologies. Contributions that highlight new advancements in efficient deep learning algorithms, efforts toward explainable AI, and the integration of physical information into data-driven frameworks are especially encouraged.

The ACC is a critical role within the IGS, with the following key responsibilities: - Monitoring the quality of products submitted by individual ACs. - Combining products from individual ACs to produce robust operational products. - Evaluating the combined products for performance and consistency. - Disseminating official IGS combined products through an operational framework. - Coordinating changes, developments, and improvements within the contributing ACs to use the latest models and standards. - Evaluating the suitability of new ACs that wish to be recognized by the IGS. The ACC is responsible for establishing the detailed specifications for IGS products, while working closely with ACs and the IGS Reference Frame Coordinator. Additionally, the ACC works closely with the ACs in the generation of other IGS analysis products, including the content of the IGS ACC website (https://igs.org/acc/). The new NASA/GA+ ACC will undertake a phased approach to ensure a smooth and thorough transition towards a fully multi-GNSS IGS, enhancing the accuracy and reliability of future GNSS products, while working towards achieving the IGS strategic goal of ?multi-GNSS Technical Excellence.? We will share more information about this transition, as well as the new ACC?s plans for ensuring that IGS products are consistently and reliably available to the global community, as it becomes available. Finally, we would like to extend our sincere thanks and appreciation to all organizations who submitted proposals for this role.

In order to continue to serve our ever-growing community, the IGS Central Bureau is announcing opportunities for secondments for several roles. Secondments are defined as the temporary assignment of a person away from their regular organization (but still remaining at said organization) to increase the number of workers and/or exchange skills at the target organisation (here the IGS CB). We are currently accepting nominations for secondments in the following disciplines: - technical translations of IGS guidelines into other languages; - data visualisation; - science communications and outreach; - user interface and website design; - graphic design; - policy and law (specifically data licensing); - improvements to the IGS Site Log Manager 2.0 software (including software development, documentation, and engagement with local or regional networks wishing to use this software); and - general CB operations. Because these opportunities are for virtual secondments, the candidate(s) will remain at -- and must be funded by -- their home institution. All seconded persons will be included as official staff members of the IGS Central Bureau (https://igs.org/governance-management/#central-bureau). Students and early career professionals are especially encouraged to apply. If your organization would like to second someone (full or part-time) to the IGS Central Bureau for some of these roles, please contact IGS CB Director Allison Craddock (craddock at igs.org) and Deputy Director L?o Martire (leo.martire at igs.org) for more information.

The new working group was proposed to continue and broad the use of NRT DORIS data for ionospheric analysis, after the great success of previous working group ?C NRT DORIS Data ?C whose objectives have been successfully achieved. The general objective of this working group is a thorough assessment on requirements, benefits, applications and prospects of near-real-time DORIS data with improved data latency, mainly focus on monitoring and modeling the Earth??s ionosphere during this new term. Using DORIS in combination with other ground and space geodetic observation techniques (e.g., GNSS) help to improve the accuracy and reliability of ionospheric maps, especially in ocean regions with pour GNSS coverage. Additionally, NRT DORIS data are currently available from more than nine satellite missions, including Jason-3, Saral, Sentinel-3A, Sentinel-3B, Sentinel-6A, SWOT, Cryosat-2, HY-2C and HY-2D. NRT RINEX DORIS data are archived at ftp://doris.ign.fr/pub/doris/data/srl/NRT/ and DIODE orbits assessable from ftp://doris.ign.fr/pub/doris/products/orbits/ssa/ As such, you are highly welcome to join this IDS working group on NRT ionospheric applications if you are currently working on or interested in this topic. Please distribute this information within your research community and send me the E-mail (wangningbo at aoe.ac.cn) before 30 September if you are interested to join this NRT DORIS Ionospheric Application Working Group.

As the chair of this newly established study group, I am pleased to invite you to participate in this this important initiative. Over the past two years, we have made significant progress in combing IGS Global Ionospheric Maps (GIMs) using ground GNSS and near-real-time DOIRS observation data. To further enhance and validate this effort, we are inviting active participation from interested members of the IGS community. The objectives of this new Study Group are: 1. developing robust methodology for IGS ionospheric products combination using ground and spaceborne observation techniques, such as GNSS and DORIS observation data. 2. improving the reliability and accuracy of the IGS provided real-time, rapid, and final Global Ionospheric Maps (GIMs) through the integration of multi-source data. 3. Promoting collaboration and knowledge sharing within the IGS community and with practitioners in the field of ionospheric mapping and modeling. We welcome individuals with expertise in ionospheric modeling, ground and space geodetic observation data processing, as well as those experienced in ionospheric product validation and combination techniques, to join us this collaboration effort. If you are interested in contributing, please submit your expression of interest, including a brief description of your relevant experience and areas of expertise, by emailing Ningbo WANG (wangningbo at aoe.ac.cn) before October 20. We look forward to your participation and contributions, as we work together to improve the quality, reliability, and usability of the IGS ionospheric products for the entire IGS community.

The reliable and stable realization of the terrestrial reference frame is an essential task in the global geodesy because it forms the basis for monitoring the system Earth. In a new joint project between Deutsches Geod?tisches Forschungsinstitut of the Technical University of Munich (DGFI-TUM) and AIUB we are targeting to improve in particular the scale realization in future ITRF solutions. This is in particular important for many applications, like the measurement of the sea level rise. One of the PhD candidates will focus on the scale in the GNSS solution. The disclosure of the pre-launch satellite antenna calibration for the Galileo and GPS Block IIIA satellites allowed for the first time to obtain a scale contributions for the ITRF from GNSS technique. Nevertheless, there remain a number of questions, e.g., how orbit modelling deficiencies map into the scale or why there are discrepancies between the GNSS-, VLBI-, and SLR-derived scale realization. The other PhD candidate will assess different solutions for the ITRF ? starting from the most recent solutions for the ITRF2020 by the three IERS combination centers. With the progress of the project new ITRF solutions become available generated by the DFGI-TUM partner that should be included as well. Finally the influence of different ITRF solutions on orbits from altimeter satellites will be derived allowing even the use of altimeter measurements for a quality control. Both PhD topics are currently subject of working groups established by the International Association of Geodesy (IAG). It demonstrates on one hand the importance of this work. On the other hand, the working groups will allow an international exchange of the PhD candidates supported by the supervisors.

Due to its importance to geophysical analysis, we reprocessed all-frequency GPS/Galileo/BDS data for the years of 2020-2022 using the latest models and PANDA software. We have uploaded them to ftp://igs.gnsswhu.cn/pub/whu/phasebias. The latest PRIDE PPP-AR ver. 3.0.5 (https://github.com/PrideLab/PRIDE-PPPAR) has been adapted to accommodate the reprocessed products. Here are some important reminders, 1) To avoid compatibility problems with PRIDE PPP-AR v3.0.5, we removed those legacy products from Wuhan FTP which are ?WUM0MGXRAP_YYYYDDD0000_01D_01M_ORB.SP3?, and ?WUM0MGXRAP_YYYYDDD0000_01D_01D_ABS.BIA?. 2) We tried our best to make sure code OSBs on all channels and phase OSBs on all frequencies are of high quality. However, there exist some problematic satellites and frequencies for earlier days in 2020 (e.g., insufficient observables, signal degradation, etc.).

The EGU25 aims to bring together geoscientists from all over the world to one meeting covering all disciplines of the Earth, planetary, and space sciences. With this session, we wish to provide a forum where scientists, especially early career researchers, can present their work and discuss their ideas with experts in all fields of geoscience. Especially, Precise Orbit Determination is nowadays essential to provide observational constraints on essential metrics defining the status of climate change, as well as a wide range of geophysical models. 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, VLBI 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; (10) simulation studies for the planned co-location of geodetic techniques in space mission GENESIS. Please consider submitting an abstract to this dedicated orbit session. The deadline for abstract submission is January 15, 2025 at 13:00 CET. We are looking forward to your contribution.

Over the past two months, we have successfully migrated from supporting FTP to HTTPS protocol for data distribution. Previously, CAS multi-GNSS Differential Code Bias (DCB) and Global Ionospheric Map (GIM) products were publicly available on our FTP server at ftp://ftp.gipp.org.cn and were transferred to IGS Data Centers including IGN, BKG, and CDDIS. As part of this transition, we are now using a new HTTPS server, which can be accessed at the following URL: https://data.bdsmart.cn/pub/ This new data center hosts CAS-generated multi-GNSS DCB, global TEC maps, as well as real-time GNSS SSR data. All SSR data have been converted into standardized formats for post-processing analysis, ensuring compliance with IGS product specifications as wel as long file naming conventions. Here is a quick overview of the available product subdirectories on the new server: ./product/bias/ CAS multi-GNSS DCB products (CAS0MGXRAP* & CAS1MGXRAP*) ./product/iono/ionex/ CAS rapid and final GIM products (CAS0OPSFIN* & CAS0OPSRAP*) ./product/rts/iono/ CAS RT-VTEC maps and combined RT-VTEC maps (CAS1OPSRTS* & IGS1OPSRTS*) ./product/rts/rtpp/ CAS real-time orbit and clock products in SP3 and CLK formats ./product/rts/brdc/ CAS combined real-time broadcast ephemeris data ... Please note that the old FTP server (ftp://gipp.org.ac.cn) will be shut down by March 1, 2025. We strongly encourage all users to adapt their software to the new HTTPS link (https://data.bdsmart.cn/pub/) for data downloads as soon as possible. If you encounter any issues or have any suggestions, please feel free to reach out to me via email at wangningbo at aoe.ac.cn In addition to the new data center, CAS regional caster is now operational for IGS real-time data stream distribution via https://igs.bdsmart.cn/.

The IGS intends to adopt this update, in the form of a new IGS reference frame called IGb20, for the alignment of its products, starting with the products of GPS week 2352 (2 February 2025). IGb20 is a simple extract from ITRF2020-u2023. It includes reference coordinates for 343 stable, well-performing, operational and historical IGS stations. The same 332 stations as in the current IGS reference frame, IGS20, were retained. 11 new stations were added in areas currently sparsely covered by IGS reference frame stations. The IGb20 files are available for download at [ ftp://igs-rf.ign.fr/pub/IGb20 | ftp://igs-rf.ign.fr/pub/IGb20 ] : - IGb20.snx.gz : IGb20 SINEX file (gzip compressed) - IGb20.ssc : IGb20 SINEX file without covariance matrix - psd_IGb20.snx : post-seismic deformation models to be used with IGb20 - soln_IGb20.snx : discontinuity list to be used with IGb20 - IGb20_core.txt : list of "core" stations recommended for the alignment of global solutions to IGb20 Since ITRF2020-u2023 is aligned in origin, scale and orientation to ITRF2020, IGb20 should not be considered as a complete new reference frame, but rather as an update to individual IGS20 station coordinates. This alignment implies that t he transformation parameters between ITRF2020 (IGS20) and ITRF2020-u2023 (IGb20) are all zero. It also implies that the switch from IGS20 to IGb20 will not introduce any significant "datum" change in the IGS products. On the other hand, the precision and accuracy of the alignment of the IGS products to the reference frame will benefit from the adoption of updated reference station coordinates. More details on the usage of the IGb20 reference frame may be found in the comment section of the SINEX file.

Both failures were caused by a problem in the storage disk of the operational server. The issue is now resolved, and the products have been uploaded to the global data centres. Apologies for any inconvenience this may have caused.
