sample correctly

Andrew Tridgell 603e0c090d AP_NavEKF3: don't reset EKx_GPS_TYPE when GPS has no vertical velocity
setting the parameter to 1 causes the following issues:

 - the GPS may not have vertical velocity at the time the parameter
   set happens, but may get it later when the GPS is fully configured

 - we may switch between GPS modules which do/don't have vertical
   velocity

 - the user may download parameters after the set(1), and end up with
   incorrect parameters they may later load onto the vehicle,
   permanently disabling use of vertical velocity

Randy Mackay b726630ef4 AP_NavEKF3: pos timeout or glitch does not reset vel if fusing successfully
vel is not reset if GPS velocity, optical flow, visual odometry or wheel
encoders are successfully being fused
2020-10-28 19:06:53 +11:00
Randy Mackay 3b38aa6d7b AP_NavEKF3: GPS change pos reset uses ResetPositonNE and ResetPositionD
Using these existing functions removes some code duplicate
non-functional change

Randy Mackay 2f1ae29a9c AP_NavEKF3: extnav data gets corrected boolean
CorrectExtNavForSensorOffset and CorrectExtNavVelForSensorOffset use
corrected boolean to avoid correcting twice
2020-10-24 12:35:58 +11:00
Randy Mackay a16de76f57 AP_NavEKF3: correct extnav position as it is recalled from the buffer
This makes extnav position correction consistent with the velocity correction
2020-10-24 12:35:58 +11:00
Randy Mackay 71487e9c10 AP_NavEKF3: gps_elements gets corrected flag
CorrectGPSForAntennaOffset uses this flag to ensure position and velocity are only corrected once
2020-10-24 08:49:33 +09:00
Randy Mackay 3d4e1cd5c5 AP_NavEKF3: CorrectGPSForAntennaOffset always corrects vel 2020-10-24 08:49:33 +09:00
Randy Mackay e25579cc00 AP_NavEKF3: correct GPS for position as it is recalled from buffer 2020-10-24 08:49:33 +09:00

Randy Mackay 6989a28bfc AP_NavEKF3: allow alt from other sources when using ExtNav
also allows using ExtNav alt when not using it for XY position
removes redundant and incorrect setting of activeHgtSource from ExtNav
which was always being overwritten by the correct value later in selectHeightForFusion
