The two topographic instruments are now integrated on-board the satellite’s platform built by Thales Alenia Space Italy: The SRAL radar altimeter developed by Thales Alenia Space Toulouse and the MicroWave Radiometer (MWR) provided by Astrium Casa Espacio.
The two other instruments dedicated to the mission will be integrated early next year—these would be the Ocean and Land Color Instrument (OLCI) developed by Thales Alenia Space Cannes, as well as the Sea and Land Surface Temperature Radiometer (SLSTR) provided by Selex Galileo.
Sentinel 3 mission will be dedicated to oceanography and monitoring of land vegetation in the frame of Copernicus (GMES) program.
