Sentinel-1A collision avoidance manoeuvres on 25 September 2018

26 September 2018

Collision avoidance manoeuvres were executed on Sentinel-1A to reduce the risk of collision with a debris, potentially occurring at 21:49 UTC on 25 September 2018.

Two 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.
