Paul Riseborough d118c8fc38 AP_NavEKF2: Fix range aid switching logic
Clarifies use of EK2_RANGE_USE_HGT and EK2_ALT_SOURCE parameters to control range finder use.
Setting EK2_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 EK2_ALT_SOURCE parameter.

Randy Mackay 43c9e13372 AP_NavEKF2: rename HGT_SOURCE_EV to HGT_SOURCE_EXTNAV
presumably EV stands for ExternalVision but we normally refer to this source as External Nav

Andrew Tridgell c83e2d7c0e AP_NavEKF2: fixed loss of GPS fusion
we must not do a storedGPS.recall unless we will be using the data,
otherwise we will lose GPS samples and risk stopping GPS fusion

Paul Riseborough de0040ad69 AP_NavEKF2: Enable use of EKF-GSF yaw estimate
Enables the yaw to be reset in flight to a value estimated from a specialised yaw estimator. This allows faster recovery if taking off with a bad magnetometer and also allows yaw alignment and GPS use to commence in-air when operating without any yaw sensing.

Andrew Tridgell 9030590a88 AP_NavEKF2: fixed use of antenna position when switching GPS primary
when GPS primary switches we were using a position which had not been
corrected for antenna offset. This was used for calculating the reset
for sensor change.

This fixes that (trivial fix) and also fixes a similar issue on
position reset

Andrew Tridgell f7e138bddd AP_NavEKF2: use parent class for intermediate static variables
this makes the code faster as well as using less memory when both EK2
and EK3 are enabled
2019-10-01 15:39:03 +10:00
Andrew Tridgell 255981c60c AP_NavEKF2: moved some of the intermediate vars to the stack
this keeps stack frames below 1k, while giving faster access to the
variables and saving more memory

Randy Mackay 94a52b3525 EKF2: RNG_USE_HGT param only used when ALT_SOURCE = rangefinder 2019-09-10 18:44:52 +10:00
Andrew Tridgell 098701ec79 AP_NavEKF2: fixed baro innovation gate when on ground with AIDING_NONE
when on the ground without a position source we would disable the
innovation gate for the barometer. This meant that a single (or small
number of) really bad baro readings would be fused into the EKF,
causing it to destabilise

Fixes #11903

Andrew Tridgell 20ebb2500b AP_NavEKF2: ensure that both AMSL and relative alt are correct after a reset
this forces the EKF origin to the GPS alt on a height datum reset if
we have GPS lock. If we don't do this then the reported AMSL alt will
drift over time away from the GPS alt when we reset while on the
ground
