Sentinel-1 operations

Sentinel-1, the first in the family of Copernicus satellites

The Sentinel-1 mission is a polar-orbiting satellite system for the continuation of Synthetic Aperture Radar (SAR) operational applications.

Sentinel-1 is a C-band imaging radar mission to provide an all-weather day-and-night supply of imagery for Copernicus user services. The first of the dual Sentinel-1 satellites, -1A, was launched on 3 April 2014 and it will be followed by the second satellite a few years later.

Dedicated to the Copernicus initiative, Sentinel-1 will ensure the continuity of C-band SAR data, building on ESA’s and Canada’s heritage SAR systems on ERS-1, ERS-2, Envisat and Radarsat.

The mission

The Sentinel-1 Mission Operations Centre (MOC) is located at ESA's ESOC establishment in Darmstadt, Germany.
