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 systems are about to start providing the user signals, and both, GPS and GLONASS are currently undergoing a significant modernization, which adds more capacity, more signals, better accuracy and interoperability, etc. This, however, also results in new challenges in data processing. Moreover, the new developments in GNSS stimulate a broad range of new applications.
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. We encourage, but not limit, submissions related to:
- Modeling and strategies in high-precision GNSS,
- Multi-GNSS potential benefit for geosciences,
- Precise Point Positioning (PPP),
- CORS services for geosciences (GBAS, Network-RTK, etc.),
- Biases and calibrations,
- New or improved GNSS products for high-precision applications (orbits, clocks, etc.),
- Ambiguity resolution and validation,
- Precise Positioning of EOS platforms
- Precise Positioning for natural hazards prevention,
- High-precision applications for geosciences,
- and more.
