priseborough 2e5ac40ef6 AP_NavEKF3: remove unnecessary stdio includes 2017-01-27 16:57:42 +09:00
priseborough 8688d1ddac AP_NavEKF3: Improve range finder selection logic
Fixes bug that could leave it locked out of range finder use.

priseborough cd6fd0ea45 AP_NavEKF3: Improvements to range finder selection logic
Enables the horizontal speed at which we switch from range finder to alternate to be adjusted.
Does not switch from range finder to alternate based on speed when speed estimate is invalid.

priseborough 39969e7d8e AP_NavEKF3: added EKF3 for EKF experimentation
AP_NavEKF3: Implement same maths as PX4/ecl EKF

Replace attitude vector states with quaternions
Remove gyro scale factor states
Add XY accel delta velocity bias estimation
Initial tuning
Add GPS body frame offset compensation

AP_NavEKF3: Fix bugs and consolidate aiding switch logic

Switching in and out of aiding modes was being performed in more than one place and was using two variables.
The reversion out of GPS mode due to prolonged loss of GPS was not working.
This consolidates the logic and ensures that PV_AidingMode is only changed by the setAidingMode function.

AP_NavEKF3: prevent multiple fusion mode changes per filter update

AP_NavEKF3: Update tuning defaults

AP_NavEKF3: Fix bug causing switching in and out of aiding
If the GPS receiver was disconnected and no data received, then then the gpsGoodToAlign check did not get a chance to run and becasue it was previously true the EKF would switch back into aiding.
This prevents this by ensuring that gpsGoodToAlign defaults to false when the check is not being performed.
An additional check has also been dded to ensure that there is GPS data to fuse before we declare ready to use GPS.

AP_NavEKF3: Fix bug preventing planes recovering from bad magnetometers
This bug created a race condition whereby if the EKF had to reset the yaw to the GPS ground course to recover from a bad magnetometer, the new heading could be over-written by the bad magnetic heading when the plane reached the height for the scheduled reset.

AP_NavEKF3: Improve switch-over to backup magnetometer
When switching over to a back up magnetometer, ensure that the earth field estimate are reset. Otherwise mag earth field estimates due to the previous failed mag could cause data from the new mag to be rejected.

AP_NavEKF3: enable automatic use of range finder height

AP_NavEKF3: Fix bug in handling of invalid range data

AP_NavEKF3: Fix height drift on ground using range finder without GPSAP_NavEKF3:

AP_NavEKF3: Handle yaw jumps due to core switches

AP_NavEKF3: Enable simultaneous GPS and optical flow use

AP_NavEKF3: fix console status reporting

AP_NavEKF3: send messages to mavlink instead of console

This allows the GCS to better handle the display of messages to the user.

AP_NavEKF3: replace deprecated function call

AP_NavEKF3: Compensate for sensor body frame offsets

AP_NavEKF3: Fix bug in median filter code

AP_NavEKF3: save some memory in the position offsets in EKF3

We don't need to copy that vector3f for every sample. A uint8_t does the job

AP_NavEKF3: Add fusion of range beacon data

AP_NavEKF3: Bring up to date with EKF2

AP_NavEKF3: Misc range beacon updates

AP_NavEKF3: Add mising accessors

AP_NavEKF3: remove duplicate include

AP_NavEKF3: Prevent NaN's when accessing range beacon debug data

AP_NavEKF3: Update range beacon naming

AP_NavEKF3: updates

AP_NavEKF3: miscellaneous changes

AP_NavEKF3: misc updates

AP_NavEKF3: misc range beacons updates

AP_NavEKF3: add missing rover default param
