Paul Riseborough 7f36add241 EKF: scale GPS vertical accuracy check when using optical flow 2018-06-09 22:23:55 +02:00
Paul Riseborough fc9f532c34 EKF: relax range finder data continuity check 2018-06-09 22:23:55 +02:00
Paul Riseborough 93c456f2b8 EKF: Improve protection against badly conditioned dVel bias covariances 
Reduces likelihood of Z delta velocity bias learning to wrong value.

Paul Riseborough 225057aaf5 EKF: Fix bug preventing use of terrain estimator 2018-06-09 22:23:55 +02:00
Paul Riseborough adb4a09beb EKF: Fix bug causing large yaw innovations when GPS is lost 2018-06-09 22:23:55 +02:00
Paul Riseborough f59cd0f5b0 EKF: Don't make detection of indoor operation dependent on optical flow 
This is required because it can take several seconds for an optical flow sensor operation to be confirmed and there are also many use cases for indoor operation where no optical flow is used.

Paul Riseborough 1562a82dc2 EKF: Add parameter to adjust on-ground movement detector sensitivity 2018-06-09 22:23:55 +02:00

Paul Riseborough 565f99254c EKF: Reduce effect of yaw gyro bias when using optical flow indoors 2018-06-09 22:23:55 +02:00
Paul Riseborough e10798bfdf EKF: Add on ground movement detector 2018-06-09 22:23:55 +02:00
Paul Riseborough 2d3b65231b EKF: Reset yaw gyro bias learning when resuming use of magnetometer 
The previous lack of yaw drift constraint will also mean that the yaw gyro bias estimate is likely to be incorrect and needs to be re-learned.

Paul Riseborough 8191068959 EKF: Don't start using mag if optical flow use is interrupted 
If magnetometer use is being inhibited because an indoor condition has been detected (optical flow and poor or no GPS) and the optical flow fusion checks fail causing the EKF to stop navigating, we do not want the EKF to start using the magnetometer.

Paul Riseborough 4889e8432c EKF: Don't fuse multi rotor drag if yaw angle is bad 2018-06-09 22:23:55 +02:00
Paul Riseborough 092a8d8f21 EKF: Fix GPS validity time check error 2018-06-09 22:23:55 +02:00
Paul Riseborough 0160aaa568 EKF: Don't use magnetometer with optical flow only nav if GPS checks are failing 2018-06-09 22:23:55 +02:00
Paul Riseborough 84516760c0 EKF: Use stricter GPS accuracy test when optical flow is being used 
This adds some hysteresis to the automated optical flow selection and also reduces likelihood of bad GPS being used when operating indoors,

Paul Riseborough 75e65901ae EKF: fix bug causing height offset when GPS use stops 
This bug causes the last vertical velocity observation to be continuously fused.
