Swarm Bravo collision avoidance manoeuvre on 2 April 2019

03 April 2019

An orbit collision avoidance manoeuvre was performed on Swarm Bravo on 2 April 2019 at 00:23 UTC for a duration of 64 seconds, equivalent to a Delta V of 0.015 m/s.

This manoeuvre lowered the spacraft's orbit, and did not contain any slew.

For safety reasons, the EFI was put in ready state before the end of a science orbit so EFI data are not available from 1 April 2019 23:47:40 UTC to 2 April 2019 01:02:37 UTC.
