Sentinel-1C, the third member of the Sentinel-1 radar satellite family, will ensure data continuity for the many services offered by the European Commission’s Copernicus program. Built on the Prima platform developed by Thales Alenia Space on behalf of the Italian Space Agency, Sentinel-1C features a C-band synthetic aperture radar (SAR) to provide radar coverage of the Earth’s entire surface. Thales Alenia Space is the prime contractor for Sentinel-1C and its twin Sentinel-1D. Airbus Defence and Space supplies both SAR payloads. Sentinel-1C will continue the critical task of delivering key radar imagery for a wide range of services and science applications, all of which benefit people down on Earth.
