About this Session

The International GNSS Service (IGS) provides the scientific community with a broad range of high-precision products supporting a wide diversity of scientific applications. Currently three fully-deployed GNSS are analyzed by IGS Analysis Centers and included in the currently running reprocessing effort: GPS (USA), GLONASS (Russia), and Galileo (Europe). Developments including additional GNSS (Chinese BeiDou, Japanese QZSS, Indian NavIC, etc.) are ongoing within the IGS.

Several components of the IGS do already support a fully consistent processing of GPS, GLONASS, and Galileo in the operational chain as well as for the currently running reprocessing effort. The continuous improvement of IGS products in this fast-moving field 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.
