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

non-functional change

Randy Mackay 2f1ae29a9c AP_NavEKF3: extnav data gets corrected boolean

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
 2020-10-20 17:11:26 +09:00
Randy Mackay 0cebde0632 AP_NavEKF3: minor restructure of how fusePosData and fuseVelData are set

Paul Riseborough 906731222d AP_NavEKF3: Fix range aid switching logic 
Clarifies use of EK3_RANGE_USE_HGT and EK3_ALT_SOURCE parameters to control range finder use.
Setting EK3_RNG_USE_HGT to a positive number to enable automatic switching between the primary height source (baro or GPS) and range finder should be disabled if any primary height source other than Baro or GPS is selected via the EK3_ALT_SOURCE parameter.
