Dear Colleagues,

The General Assembly of the European Geosciences Union will be held in
Vienna, Austria, 8-13 April 2018.

We draw your attention in particular to session

*G1.3 - High-precision GNSS: methods, open problems and Geoscience
applications*
http://meetingorganizer.copernicus.org/EGU2018/session/26517

This session is an activity of:
- IAG SC4.4. Multi-constellation GNSS and
- IAG-ICCT JSG 0.10 High-rate GNSS

Session G1.3 description:
In the past two decades high-precision GPS has been applied to support
numerous applications in Geosciences. Currently, there are two fully
operational Global Navigation Satellite Systems (GNSS), and two more are in
the implementation stage. The new Galileo and BDS systems already provide
usable signals, and both, GPS and GLONASS, are currently undergoing a
significant modernization, which adds more capacity, more signals, better
accuracy and interoperability, etc. Meanwhile, the huge technology
development provided GNSS equipment (in some cases even at low-cost) able
to collect measurements at much higher rates, up to 100 Hz, hence opening
new possibilities. Therefore, on one side, the new developments in GNSS
stimulate a broad range of new applications for solid and fluid Earth
investigations, both in post-processing and in real-time; on the other
side, this results in new problems and challenges in data processing which
boost GNSS research. Algorithmic advancements are needed to address the
opportunities and challenges in enhancing the accuracy, availability,
interoperability and integrity of high-precision GNSS applications.

This session is a forum to discuss new developments in high-precision GNSS
algorithms and applications in Geosciences; in this respect, contributions
from other branches in Geosciences (geodynamics, seismology, tsunamis,
ionosphere, troposphere, etc.) are very welcome.

The session will be remarkably enriched by two invited talks given by
distinguished speakers: Prof. Thomas Herring from MIT, USA and Dr. Amir
Khodabandeh from Curtin University, Australia.

We encourage, but not limit, submissions related to all aspects of the
following issues:
- Modeling and strategies in high-precision GNSS,
- Multi-GNSS benefit for Geosciences,
- Multi-GNSS processing and product standards,
- Inter-system and inter-frequency biases and calibrations,
- New or improved GNSS products for high-precision applications (orbits,
clocks, UPDs, etc.),
- Precise Point Positioning (PPP, PPP-RTK),
- High-rate GNSS,
- GNSS and other sensors (accelerometers, INS, ecc.) integration for
high-rate applications,
- Ambiguity resolution and validation,
- CORS services for Geosciences (GBAS, Network-RTK, etc.),
- Precise Positioning of EOS platforms,
- Precise Positioning for natural hazards prevention,
- Monitoring crustal deformation and the seismic cycle of active faults,
- GNSS and early-warning systems,
- GNSS reflectometry,
- Time and frequency transfer,
- High-precision applications for Geosciences,
- and more.

Accepted Authors may also consider submitting their manuscripts to a
special issue on GNSS in Measurement Science and Technology:
*http://iopscience.iop.org/journal/0957-0233*
edited by Dr. Jacek Paziewski and Prof. Mattia Crespi.

*Deadline for receipt of abstracts is 10 January 2018:*

Please consider submitting an abstract for this session or contact us
directly if you have any questions.
