Copernicus Sentinel-1B anomaly (3rd update)

14 January 2022

Following the previous news on the Sentinel-1B anomaly that occurred on 23 December 2021, further attempts to reactivate the proper functioning of the satellite power system’s affected unit were executed, but were not successful.

All necessary investigations to identify the root cause and possibly fix the issue are on-going.

The satellite remains under control, the thermal control system works properly and the regular orbit control manoeuvres are routinely performed.

We apologize for the inconvenience caused.
