Copernicus Sentinel-1B anomaly (2nd update)

07 January 2022

Following the previous news on the Sentinel-1B anomaly that occurred on 23 December 2021, the resuming of the operations was carefully prepared including the on-board configuration changes preventing the anomaly to occur again.

However, during the preparation of the recovery operations, it became clear that the initial anomaly was a consequence of a potential serious problem related to a unit of the power system of the Sentinel-1B satellite. The operations performed over the last days did not allow to reactivate so far a power supply function required for the radar operations.

Further investigations to identify and remedy the root cause will be performed over the next days.

We apologize for the inconvenience caused.
