Collision avoidance manoeuvres were executed on Copernicus Sentinel-1A to reduce the risk of collision with a debris, potentially occurring at 20:24 UTC on 3 February 2019.

Three Copernicus Sentinel-1 data download links through the European Data Relay Satellite System (EDRS) had to be cancelled due to these orbit manoeuvres.

SAR acquisitions taken within few hours before this event, and planned to be downlinked through EDRS, may have been affected.
