Scientific Applications Enabled by the International GNSS Service (IGS) and Associated Improvements to GNSS Products

Session ID#: 158175

Session Description:
The International GNSS Service (IGS) provides a broad range of high-precision openly available geodetic products supporting diverse scientific applications for peaceful usage. The recently finished reprocessing effort (“repro3”) includes three out of the four currently fully deployed GNSS constellations: GPS, GLONASS, and Galileo. Developments to include additional GNSSs (BeiDou, QZSS, NavIC, etc.) are ongoing within the IGS.

Advances in IGS product development may stimulate new multi-GNSS scientific applications in a wide range of potential applications including Earth rotation, tectonophysics, seismology and the earthquake cycle, glaciology and glacial isostatic adjustment, global environmental change, sea level, terrestrial water storage, time transfer, space weather and atmospheric science, disaster and tsunami early warning, and fundamental physics. The continuous improvement of IGS products – with constantly evolving satellites, systems, signals, models, and data analysis methodology – is a scientific challenge.

This session solicits presentations on scientific applications enabled by IGS products and new science enabled by improvements to quality and breadth of GNSS products.
