List of Sentinel satellites

The Sentinel satellites are a family of Earth observation satellites developed by the European Space Agency (ESA) for the Copernicus Programme of the European Union.

The program includes radar, optical, oceanographic, and atmospheric-monitoring satellites and payloads operating in low Earth orbit and geostationary orbit. Sentinel missions provide data for environmental monitoring, climate studies, emergency management, agriculture, and maritime surveillance.

The classes are Sentinel-1, Sentinel-2, Sentinel-3, Sentinel-4, Sentinel-5, Sentinel-6, Sentinel-7.
