High-precision GNSS: methods , open problems and Geoscience applications

Convener: PawelWielgosz

Co-conveners: Elisa Benedetti，Mattia Crespi，Xingxing Li ，Felix Perosanz 

In the past two decades high-precision GPS has been applied to support numerous applications in Geoscie nces. 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 modern ization, 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 related to activities of IAG SC4.4 'Multi-constellation GNSS' and IAG-ICCT JSG 0.10 'High-rate GNSS'. It 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, seismo logy, tsunamis, ionosphere, troposphere, etc.) are very welcome.

We encourage, but not limit, submissions related to:
-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，
-High-precision applications for Geosciences,
-and more.
