| Session Description | The global navigation satellite systems (GNSS), as a powerful space-borne geospatial infrastructure, have undergone significant developments in the past two decades. The next decade will herald rapid growth of the satellite positioning technology and systems with a high-accuracy positioning capability anywhere and anytime using new generation multi-GNSS systems; such as Galileo, Glonass, Compass, QZSS, EGNOS and WAAS. Coupled with the ground-based facilities and other satellite systems, GNSS are considered as a robust atmosphere remote sensing technology and have been used extensively for studying atmosphere, weather and climate in addition to its routine usages for real-time, high-precision geodetic positioning. The current geodesy-capable satellite programs that underpin our enhanced understanding of the earth system and atmospheric processes, severe weather, climate change and environment include CHAMP, DORIS, GRACE, COSMIC, MetOp, TerraSAR-X, etc. In this context, the synergy between GNSS and atmospheric modelling becomes an important part of geodetic research. This session is dedicated to the emerging research topics related to new generation GNSS technology, systems and innovative applications. We welcome contributions from the following areas: GNSS meteorology (e.g. new developments in GNSS radio occulcation, GNSS for severe weather, dynamics of troposphere and ionosphere, now- casting applications, new satellite programs for atmosphere sounding, scatterometery, reflectometry, atmospheric tomography techniques), recent developments in GNSS data processing algorithms (e.g. novel multi-GNSS algorithms, PPP-RTK, improved ambiguity solutions), enhanced positioning with the aid of extensive meteorological modelling and synergies between NWP and GNSS, latest developments in national multi-sensor and multi-purpose positioning infrastructure. |
