In recent years we have witnessed notable progress in signals, services, and satellite deployment of Global Navigation Satellite Systems (GNSS). Modernizing operational GNSS systems and developing new constellations have moved us towards a new stage of multi-constellation and multi-frequency observations. Meanwhile, the technology development provided high-grade GNSS equipment to collect measurements at much higher rates, up to 100 Hz, of lower noise and multipath impact. Moreover, the recent progress in low-cost GNSS chipsets catalyzes an expansion of traditional satellite navigation to novel areas of science and industry. Therefore, on one side, the 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, such progress results in further problems and challenges in data processing, which boosts 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 advances in high-precision GNSS algorithms and their applications to Geosciences. Contributions from other branches of Geoscience, such as geodynamics, seismology, tsunamis, ionosphere, troposphere, etc., are also welcome.
We encourage but do not limit submissions related to:
- Processing algorithms in high-precision GNSS,
- Multi-GNSS benefits for Geosciences,
- Multi-constellation GNSS processing and product standards,
- High-rate GNSS,
- Low-cost receiver and smartphone GNSS observations for precise positioning, navigation, and geoscience applications,
- Precise Point Positioning (PPP, PPP-RTK) and Real Time Kinematic (RTK),
- GNSS and other sensors (accelerometers, INS, etc.) fusion,
- GNSS products for high-precision applications (orbits, clocks, uncalibrated phase delays, inter-system and inter-frequency biases, etc.),
- Troposphere and ionosphere modeling with GNSS,
- 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.
