GNSS station NATT of Rénag network located in the commune of Parves-et-Nattages (Ain)


Description : This image shows the structure supporting the solar panels feeding the GNSS (Global Navigation Satellite System) NATT receiver of the Résif-Rénag network, and the 3G modem allowing transmissions, as well as the mast supporting the GNSS antenna. The 2 electrical boxes contain one the battery pack (2x24V: 4 batteries 12V 60 Ah), the other, the receiver and the modem. This station was deployed during 2016 on land overlooking the Rhône and belonging to the municipality of Parves-et-Nattages (Ain), at an altitude of 381m. This new station is part of the Résif-Rénag network, composed for the northern part of the French Alps of about twenty permanent GPS stations allowing the precise study (measurement of annual displacement speeds in the order of mm) of the deformation of the FrenchAlps, and more locally, to study the faults of the region (mainly the Cat Fault and the Vuache Fault). This observation site is part of the French seismological and geodetic network Résif, a national research infrastructure dedicated to the observation and understanding of the structure and dynamics of the Internal Earth. Résif is based on high-tech observation networks, composed of seismological, geodetic and gravimetric instruments deployed in a dense manner throughout France. The data collected make it possible to study with high spatial and temporal resolution the deformation of the ground, surface and deep structures, seismicity on a local and global scale and natural hazards, and more particularly seismic events, on French territory. Résif is part of the European (EPOS - European Plate Observing System) and global systems of instruments used to image the Earth's interior as a whole and to study many natural phenomena.
