Paul Riseborough ff2782b790 AP_NavEKF2: Parameter changes to reduce noise on gyro bias estimates 2015-11-18 20:17:03 +09:00
Paul Riseborough 2193103586 AP_NavEKF: Reduce time to switch after an IMU fault
This revised threshold value is still double the maximum that has been observed in flight logs so far with healthy sensors
The previous value was too slow to switch for sudden IMU gyro faults
We can afford an ocasional false trigger becasue the front end will only select another instance if it is healthy and has lower errors

Paul Riseborough c9eea98142 AP_NavEKF2: Improve terrain height estimation
The ad-hoc scaling of error growth has been replaced with a consistent method that uses the main nav filters published vertical velocity uncertainty and the terrain gradient assumption.

Paul Riseborough d820a538d5 AP_NavEKF2: Make magnetometer data available status global

Paul Riseborough 04228e0b3b AP_NavEKF2: Rework selection of height measurements for fusion
GPS height has been added as a measurement option along with range finder and baro
Selection of the height measurement source has been moved into a separate function
Each height source is assigned its own measurement noise
If GPS or baro alt is not able to be used, it reverts to baro
When baro is not being used, an offset is continually calculated which enables a switch to baro without a height step.

Paul Riseborough 9b82b2200c AP_NavEKF2: Fix plane in-flight yaw reset
The copter method was being used for plane and the plane method was not being run due to the change in flight status not being detected.
The plane reset method did not trigger if the EKF had already dragged the velocity states along with the GPS or could align to an incorrect heading.
The method has been reworked so that it resets to the GPS course, but only if there are inconsistent angles and large innovations.
To stop a failed magnetometer causing a loss of yaw reference later in flight, if all available sensors have been tried in flight and timed out, then no further magnetoemter data will be used
