Copernicus Sentinel-6B enters service

After a smooth launch and deployment, the Copernicus Sentinel-6B satellite has formally entered service.

With the addition of Sentinel-6B, the Sentinel-6 constellation now offers a near-real-time service for monitoring sea level and surface currents.

Also, the new satellite is now providing wind speed measurements with improved accuracy and resolution.

Peter de Smet, Director of the European Space Agency's Earth Observation Programmes - "The Sentinel-6 mission is a key component in the Copernicus constellation, providing crucial information on sea level and ocean currents."

Optical and Microwave Radiometers

Sentinel-6B is equipped with two instruments: the Poseidon-4 Advanced Microwave Radiometer and the Ocean Altimeter.

The Poseidon-4 Advanced Microwave Radiometer measures the microwave radiation emitted by the ocean surface, while the Ocean Altimeter measures the distance between the satellite and the ocean surface.

These two instruments provide data on sea level and ocean surface height, which is essential for monitoring sea level rise and ocean currents.
