ESA is developing five families of SENTINEL missions specifically for Copernicus. The SENTINELS will provide a unique set of observations for Copernicus, starting with the all-weather, day and night radar images from SENTINEL-1 to be used for land and ocean services.

SENTINEL-2 will deliver high-resolution optical images for land services and SENTINEL-3 will provide data for services relevant to the ocean and land. SENTINEL-4 and SENTINEL-5 will provide data for atmospheric composition monitoring from geostationary and polar orbits, respectively.

The applications fall into six main categories: services for land management, services for the marine environment, services relating to the atmosphere, services to aid emergency response, services associated with security and services relating to climate change.
