G51A:
Scientific Applications Enabled by the International GNSS Service (IGS) and by Improvements to GNSS Products I


Submit an Abstract to this Session


Session ID#: 57953

Session Description:
For nearly 25 years, products of the International GNSS Service (IGS) have 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.  The recent inclusion of Galileo (Europe) and Beidou (China) to the established GNSS—GPS(US) and GLONASS (Russia)—will eventually increase the number of satellites to >100, offering potential new scientific applications.  Moreover, 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.  For this session we solicit presentations on scientific applications that are enabled by IGS products, and on improvements to quality and breadth of GNSS products that will enable new science.
