Andrew Tridgell 43df0022e1 use common variables for EKF 2019-10-06 10:58:07 +11:00
Andrew Tridgell 9ad9fe42bc 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 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

Various comments where getting out of sync with one-another, and
having everything in one place lets you match values against types.

priseborough efdc651d1a AP_NavEKF2: Require reboot after changing ALT_SOURCE parameter
Toggling between alt sources in flight using the parameter can have unpredictable effects due to the various height offsets and the possibility that the data source may be unavailable.

priseborough 027552ef44 AP_NavEKF2: Fix default behaviour for height origin corrections
Previous default was to apply in-flight height origin changes to local position instead of to reported origin height. This caused problems with copters that took off before getting GPS lock.
