Scientific Applications Enabled by the International GNSS Service (IGS) and by Improvements to GNSS Products
Session ID#: 77119
Session Description:
Since more than 25 years, the International GNSS Service (IGS) has increasingly enabled a broad diversity of scientific applications, such as 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, natural hazards and tsunami early warning, and fundamental physics. Currently three global systems are fully deployed, namely GPS (USA), GLONASS (Russia), and Galileo (Europe). The Chinese BeiDou system is under development. The number of GNSS satellites will soon rise to >100, potentially offering new scientific applications. The continuous development and improvement of IGS products in this fast-moving field with new GNSS satellites, systems, signals, models, and GNSS data analysis methodology is a scientific challenge. This session solicits presentations on scientific applications that are enabled by IGS products, and on improvements to quality and breadth of GNSS products that enable new science.
