Collision avoidance manoeuvres were executed on Sentinel-1B to reduce the risk of collision with an old third stage rocket fragmentation debris, potentially occurring at 01:24 UTC on 28 February.

Two Copernicus Sentinel-1B data download links through the European Data Relay Satellite System (EDRS), taking place between 02:29 UTC and at 04:30 UTC on 28 February, had to be cancelled due to these orbit manoeuvres.

SAR acquisitions taking place slightly before and during this period may have been affected.
