Abstract
The GNSS antenna is visible in the photo. It is part of the station SLVT located in La Couvertoirade (Aveyron) and is integrated into the Permanent National GNSS Network (Rénag), part of Epos-France, a research infrastructure (RI) in the field of solid Earth, dedicated to observation. Its aim is to advance our knowledge of the Earth system in all its diversity and complexity. In October 2023, Epos-France took over from the French seismological and geodetic network Résif-Epos, which deployed modern instrumentation (seismometers, GNSS stations and gravimeters) across France to measure deformations of the Earth's surface. All French research on the solid Earth will gradually join the IR Epos-France, which represents the French participation in EPOS, the European research infrastructure whose mission is to integrate national and transnational IRs in charge of monitoring and understanding the dynamic and complex system of the solid Earth.
