Sentinel-2 carries an innovative high-resolution multispectral imager with 13 spectral bands for a new perspective of our land and vegetation. Once its data are acquired, they are sent to the core Sentinel ground stations in Italy, Spain and Norway. For continual data delivery, the satellite is also equipped with a laser terminal to transmit data to satellites in geostationary orbit carrying the European Data Relay System (EDRS). These satellites then transmit the Sentinel-2 data to the ground. Complementing the Sentinel ground-station network, EDRS ensures the timely availability of large volumes of data. Sentinel-1 carries the same laser terminal.
