Two new permanent GNSS stations joined the Rénag national permanent GNSS network this year, in the Pyrenees and the Alps. They complement the historical network and will provide a better understanding of the tectonic deformation associated with these mountain ranges. Observations are available in RINEX format via the EPOS-GNSS portal or the Rénag ftp. Station metadata are available on the M3G interface.
Observatoire Midi-Pyrénées has installed a new station, TAOU, at 2340 m altitude near the summit of Taoulet, in the Domaine du Tourmalet (Hautes-Pyrénées), with a clear horizon. The installation was made possible thanks to collaboration between GET (UMR 5563), UAR 831 and IRAP (UMR 5277). The GNSS receiver records observations from the GPS, Glonass and Galileo constellations at 20 Hz, with a local storage capacity of around one week. The station is powered by a 150 W solar panel and batteries with an autonomy of 7 days. Battery voltage is continuously monitored remotely.
The OGSA GNSS station is located on the Col du Lautaret (Hautes Alpes) in the grounds of the Joseph Fourier alpine station. It is co-located with the RLBP-RAP station of the same name, and has been managed and financed by Edytem, Osug and IsTerre since its commissioning in September 2022. Integrated as a Rénag partner station, all data from the station are available through the usual channels, and it benefits from the quality control set up by the SNO.
