Ground Segment - Sentinel-5 - Sentinel Online
In the Copernicus Programme the Sentinel missions are served by the Copernicus core ground segment, the collaborative ground segment and the Copernicus ‘contributing missions' ground segments.
These ground segments monitor and control the Sentinel spacecrafts, ensuring measurement data acquisition, processing, archiving and dissemination to final users. They are responsible for performing conflict-free mission planning according to a pre-defined operational scenario, and ensuring the quality of data products and performance of the space-borne sensors by continuous monitoring, calibration and validation activities, guaranteeing overall performance of the mission. Figure 4 shows the Copernicus Ground Segment Architecture.

As far as the Sentinel-5 mission is concerned, the EUMETSAT EPS-SG ground segment serves as a Copernicus ‘contributing mission' ground segment, since the Sentinel-5 instrument is embarked on-board the MetOp-SG A spacecraft. As such the EPS-SG ground segment provides Sentinel-5 with specific control functions, data reception, data processing, data dissemination and data archiving facilities. The EPS-SG ground segment is developed, implemented and operated by EUMETSAT. ESA delivers processing algorithms, prototype processors, and associated reference test data to EUMETSAT as input for the development of the Sentinel-5 specific elements of the EPS-SG ground segment.
