Sentinel-1 is the first satellite dedicated to Europe’s Copernicus environmental monitoring programme. This new satellite carries an advanced synthetic aperture radar that works in several specialised modes to provide detailed imagery for monitoring the oceans, including shipping lanes, sea ice and oil spills. It also provides data to map changing land cover, ground deformation, ice shelves and glaciers, and can be used to help emergency response when disasters such as floods strike and to support humanitarian relief efforts at times of crisis.
