Randy Mackay 87212e0fbf AP_NavEKF3: remove unused EK3_GSF_DELAY param 2021-08-14 11:05:38 +09:00
Paul Riseborough d90c67a079 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.
