Sentinel-1D spacecraft with AIS antennas

The AIS antenna assemblies have been mounted onto the spacecraft in Kourou’s clean room and Sentinel-1D has undergone checks and functional tests. These checks are vital because repairs cannot be performed in space.

Together with its sibling Sentinel-1C, Sentinel-1D will significantly enhance the capabilities of the Copernicus Earth observation programme.

The mission will continue to deliver radar images of Earth’s surface, performing in all weathers, day-and-night, providing a service vital for users who depend on frequent updates of critical data, such as disaster response teams, environmental agencies, maritime authorities and climate scientists.
