@ -17,6 +17,13 @@ change warranting a new major release:
# [unreleased]
## Added
- In case the ACS Controller does recognize more than one RW to be invalid and therefore not
available, it does not perform pointing control but aborts shortly after `sensorProcessing`. If the
problem persits for 5 ACS cycles, the `MULTIPLE_RW_INVALID` event is triggered, which invokes the
transition of the `AcsSubsystem` to safe mode.
## Changed
- Igrf13 model vector now outputs as uT instead of nT
@ -25,6 +32,9 @@ change warranting a new major release:
## Fixed
- Fixed values for GYR sensor fusion
- Fixed speed types for `rwHandlingParameter`
- Pseudo inverse used for allocating torque to RWs and RW antistiction now actually consider the
state of the RWs
# [v1.27.2] 2023-02-14
