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.

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 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

Andrew Tridgell 96c6544997 AP_NavEKF3: moved intermediate variables to common memory
this moves intermediate variables from being per-core to being common
between cores. This saves memory on systems with more than one core by
avoiding allocating this memory on every core.

This is an alternative to #11717 which moves memory onto the stack. It
doesn't save as much memory as #11717, but avoids creating large stack
frames

Andrew Tridgell 742ae0b750 AP_NavEKF2: set origin on all cores
when EKF origin is set, make sure it is set on all cores
2019-07-29 10:08:22 +10:00
Andrew Tridgell 5db41147ed AP_NavEKF2: restrict setting of EKF origin
only allow EKF origin to be set if EKx_GPS_TYPE is set to 3, which is
used for indoor operation

Andrew Tridgell 567c902e75 AP_NavEKF2: force first EKF lane when disarmed
this ensures we consistently fly with EKF lane1 if it is healthy at
the point we arm. Otherwise the choice of lane will be a lottery.

This is important as many systems have quite different filtering and
vibration characteristics on their different IMUs. We by default
enable fast sampling only on the first IMU for example, which means
the 2nd and 3rd IMUs are more vulnerable to high freq causing
aliasing.

Andrew Tridgell 3073c4da7a AP_NavEKF2: added checkLaneSwitch()
this allows the vehicle code to ask the EKF to change lanes if it is
about to do an EKF failsafe

Andrew Tridgell df4fc0fff0 AP_NavEKF2: default EK2_MAG_EF_LIM to 50
this was supposed to be part of the original PR (agreed with Paul to
enable by default)
2019-06-08 20:24:58 +10:00
Andrew Tridgell 3835d2613e AP_NavEKF2: added EK2_MAG_EF_LIM parameter
this sets a limit on the difference between the earth field from the
WMM tables and the learned earth field inside the EKF. Setting it to
zero disables the feature. A positive value sets the limit in mGauss.

Andrew Tridgell cc62998d40 AP_NavEKF2: fixed bug in EKF lane selection
this fixes an issue in selecting the best lane to change to when we
have 3 or more EKF cores. The bug is that if the current lane is
unhealthy it would always choose the last healthy lane instead of
choosing the lane with the lowest score
