Andrew Tridgell c1f72d6683 AP_AHRS: build fix 2021-07-22 19:07:36 +09:00
Paul Riseborough b2c24a0b58 AP_NavEKF3: Revert IMU and wind speed process noise parameter defaults 
These give noisier state estimates, but are more robust to rapid changes in IMU biases.
TODO implement a means of using the modified parameters when there are more than one EKF instance running with IMU's that are sampling at a higher rate.

Paul Riseborough 762529a987 AP_NavEKF3: retune wind process noise for better airspeed fault detection 2021-07-22 19:07:36 +09:00
Paul Riseborough dd9cc70ad4 AP_NavEKF3: Fix bug preventing copter wind estimation at low speed 
Also re-tunes process noise default for smoother wind velocity state estimates.

Paul Riseborough 84693ea3c4 AP_NavEKF3: Revert EK3_BETA_MASK parameter extension
