Andrew Tridgell 80f7906744 AP_NavEKF3: removed inhibitGps and inhibitGpsVertVel options 
these were unused
 2020-12-01 10:33:50 +11:00
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

Peter Barker 914629351f AP_NavEKF3: use scalar rather than array for state-prediction-allowed

Randy Mackay d1983b0b77 AP_NavEKF3: fixup source param conversion

this fixes a bug that happens with VISION_SPEED_ESTIMATE from a
companion computer, which may come in before the EKF buffers are
allocated. That causes a push to an uninitialised ringbuffer which
triggers memory corruption

found using the new memory guard system

Andrew Tridgell 8a4b0f858a AP_NavEKF3: reset body mag variances at key points 
we need to reset the body mag variances if we change sensors or if we
are starting 3D fusion. When not doing 3D fusion we zero the
variances, so they must be initialised again when we restart
fusion. This fixes a bug in handling the variances on a 2nd flight

Harshit Kumar Sankhla edc3709653 AP_NavEKF3: implement sensor affinity using EK3_AFFINITY parameter 
this allows the EKF core index to be used to select a GPS/baro/mag
instance. This is an alternative to GPS blending that allows EKF lane
switching to be used to select the right combination of GPS and IMU
add logging to XKFS message

Paul Riseborough 318811210f AP_NavEKF3: Don't perform emergency yaw reset unless commanded externally 
This limits the use of the reset to situations where it is a last ditch resort before a lane switch and failsafe.
This will limit false positives for general deployment, but still provide protection from fly-aways at the cost of some increase in reaction time.
