The Sentinel-3 Payload Data Ground Segment will be in charge of executing the acquisition, processing, archiving and dissemination of data from the OLCI (Ocean and Land Colour instrument), the SLSTR (Sea and Land Surface Temperature Radiometer), the SRAL (Synthetic Aperture Radar Altimeter), the MWR (Microwave Radiometer) instruments, and the GNSS and DORIS assembly embarked in the Sentinel-3 satellite. The Sentinel-3 Payload Data Ground Segment will be consisting of centres with the following functionalities:

  • Core Ground Station providing acquisition and Near-Real-Time LAND Processing functionality;
  • Land Centre(s) providing Offline (Short-Time-Critical & Non-Time-Critical) L1 & Land L2 Processing, User Interface and Long Term archiving functionality for LAND products;
  • Marine Centre providing Near-Real-Time & Offline L0/L1 & Marine L2 Processing, Mission Planning, Mission Performance Monitoring, Auxiliary Data Coordination, User Interface and Long Term archiving functionality for MARINE products;
  • Mission Performance Centre providing Mission Performance Monitoring.

    Circulation, Short Term Archiving, Online Archiving and Monitoring functionality are common to all Centres.
