Copernicus: data from the Sentinel-1B satellite has not been received since December 23
The Sentinel-1B radar satellite, launched in April 2016 by the Russian Soyuz-2 rocket from the Kourou cosmodrome, has failed, troubleshooting is underway. This is reported on the website of the European Copernicus program.
Data from the spacecraft has not been received to Earth since December 23, 2021. "It turned out that the initial anomaly was the result of a potentially serious problem related to the Sentinel-1B satellite power system unit," Copernicus said in a statement.
Copernicus satellites, in particular Sentinel-1A and Sentinel-1B, have been repeatedly used to monitor the territory of Russia.
In July 2021, Defense Blog wrote that Russian radars located in the Rostov region near the border with Ukraine "distorted" the images taken by the European Sentinel-1 satellite.
In November 2020, the Covert Shores blog published "distorted" Sentinel-1 images of Russian warships in the Barents Sea, noting that publicly available Sentinel-1 images can be used to determine the location of ground or surface radars.
