@ -27,14 +27,18 @@ will consitute of a breaking change warranting a new major release:
- Bugfix in PLOC MPSoC HK set: Set and variables were not set valid.
- The `PTG_CTRL_NO_ATTITUDE_INFORMATION` will now actually trigger a fallback into safe mode
and is triggered by the `AcsController` now.
- Updated QUEST and Sun Vector Params to new values.
- Fixed a corner case, in which an invalid speed command could be sent to the `RwHandler`.
## Changed
- `FusedRotationRate` now only uses rotation rate from QUEST and STR in higher modes
- QUEST and STR rates are now allowed per default
- Changed PTG Strat priorities to favor STR before MEKF.
- `MathOperations` functions were moved to their appropriate classes within the `eive-fsfw`
- Changed pointing strategy for target groundstation mode to prevent blinding of the STR. This
also limits the rotation for the reference target quaternion to prevent spikes in required
rotation rates.
- Updated QUEST and Sun Vector Params to new values.
