<br>
The virtual General Assembly of the European Geosciences Union
will take place from April 19 – 30, 2021. We draw your attention
in particular to the session:<br>
G1.3 High-precision GNSS: methods, open problems and Geoscience
applications<br>

Session description:<br>
In recent years we have witnessed a remarkable progress in terms
of signals, services and satellite deployment of Global
Navigation Satellite Systems (GNSS). The modernization of fully
operational GNSS systems and the development of new
constellations, have seen us move towards a new stage of
multi-constellation and multi-frequency observations. 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.<br>
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.<br>
We encourage, but not limit, submissions related to:<br>
- Modelling and processing strategies in high-precision GNSS,<br>
- Multi-GNSS benefit for Geosciences,<br>
- Multi-GNSS processing and product standards,<br>
- Inter-system and inter-frequency biases,<br>
- New or improved GNSS products for high-precision applications
(orbits, clocks, UPDs, etc.),<br>
- Precise Point Positioning (PPP, PPP-RTK) and Real Time
Kinematic (RTK),<br>
- High-rate GNSS,<br>
- GNSS and other sensors (accelerometers, INS, etc.) integration
for high-rate applications,<br>
- Ambiguity resolution and validation,<br>
- CORS services for Geosciences (GBAS, Network-RTK, etc.),<br>
- Precise Positioning of EOS platforms,<br>
- Precise Positioning for natural hazards prevention,<br>
- Monitoring crustal deformation and the seismic cycle of active
faults,<br>
- GNSS and early-warning systems,<br>
- GNSS reflectometry,<br>
- Low-cost receivers and smartphone GNSS observations for
precise positioning, navigation and geoscience applications.<br>
<br>
The deadline for abstract submission is January 13, 2021 at
13:00 CET.<br>
<br>
Please consider submitting an abstract for this session or
contact us directly if you have any questions.<br>
<br>
Sincerely,<br>
