Resumen o abstract:
In this presentation, we will review the operating principles of Global Navigation Satellite Systems (GNSS). We will then discuss their importance and versatility for geosciences, highlighting both their applications in precise positioning (crustal deformation, earthquake monitoring) and their derived uses for atmospheric and environmental measurements (GNSS reflectometry, radio occultation). A substantial focus will be dedicated to an original application of GNSS for meteorological and climate monitoring, based on either ground-based antennas or GNSS receivers installed on ships. Finally, we will emphasize the value of low-cost GNSS devices for all these applications, highlighting their performance, accessibility, and the new opportunities they enable.

Sobre el expositor:
Pierre Bosser is an associate professor in geodesy and GNSS at Lab-STICC / ENSTA, IP Paris, Brest, France. He received an engineering degree from the École Nationale des Sciences Géographiques, Marne-la-Vallée, France, in 2004, and a Ph.D. in Environmental Science from Université Pierre et Marie Curie, Paris, France, in 2008. At ENSTA, he is currently the head of the Hydrography, Oceanography, and Positioning group. His research interests include high-precision GNSS data processing and its applications in meteorology, oceanography, and hydrography.
