* EKF: Do not delay reversion to no-aiding mode if parameter initiated
* EKF: Move no-aid reversion resets to helper functions
* EKF: Prevent unwanted fusion of velocity data during no aiding mode
- zero thrust integrator on initialisation, we already have a cruise throttle
variable
- if initialising from in_air condition set last throttle setpoint to
cruise throttle (_in_air ? throttle_cruise : 0.0f);
* Reverse the linked list of data_validator_group and maintain a first node
for search from index 0
Fixes issue PX4/Firmware#8644
* fix code style
* validator: fix shadowing of 'sibling' argument
The if() statement was there as provision to do something different with the speed demand derivative limits if an abnormal condition was present, however we have no basis for assigning different limits at this point in time.
* Revert "EKF: Release flow speed limit with altitude gained"
This reverts commit e70206f74b.
* Revert "fix code style"
This reverts commit 76bf70121c.
* Revert "Reverse the linked list of data_validator_group and maintain a first node"
This reverts commit 32482e7644.
* fix typo
* EKF: use baro if it was reset to baro from ev
* EKF: set vert_pos_reset if resetting to ev hgt
otherwise the position controller will not reset the setpoint -> leading to unwanted altitude changes
Gate size class variables should not be initialised to zero, because it will cause a /0 error if fuseVelPosHeight() is called before they are set to their respective parameter values.
When GPS use is gained whilst flying using optical flow data, the sudden release of the speed limit is unannounced to the operator and can cause unexpected acceleration.
This patch releases the speed limit as height is gained, but does not reduce it when the vehicle descends, unless GPS use is lost.
This enables the EKF to use an additional NE velocity measurement. This can be used to improve position hold stability when landing using a beacon system for positioning by fusing the beacon velocity estimates.
Apply a dead-zone to the vertical position innovation if using baro for height and if in the ground effect region during and just after takeoff.
Method needs to be activated externally.
Turns off automatically after 10 seconds or if specified height gained.
