About us

CERSAT is the Satellite Data Processing and Distribution Center of Ifremer, the French Research Institute for Exploitation of the Sea. It was created in 1991 as part of the ESA (European Space Agency) ground segment for the ERS-1 and ERS-2 Earth Observation satellites, performing off-line processing of their "low-bit rate" sensors. CERSAT has then evolved towards a multi-mission data centre for archiving, processing and validating data from multiple spaceborne sensors (such as altimeters, scatterometers, radiometers, SAR,...) with a focus on sea surface parameters and air-sea interactions.
