Peter Barker 11f31c2851 AP_NavEKF2: take EAS2TAS from AHRS rather than airspeed 2019-06-06 12:44:36 +10:00
Andrew Tridgell e9ed3540f1 AP_NavEKF2: constrain field by table after fusion
this should make for faster convergence
2019-06-03 12:21:29 +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

Peter Barker 3a79ae4eca AP_NavEKF2: use union to alias array and struct access to states
This avoids creating two pointers of different types to the same memory.

Having two pointers to the same memory can lead to the compiler
optimising code such that a write to one pointer is rearranged to be
either before or after a read from the other pointer depending on which
is deemed faster - not a good outcome.

Andrew Tridgell 4d4e66d825 AP_NavEKF2: removed create() method for objects
See discussion here:

  https://github.com/ArduPilot/ardupilot/issues/7331

we were getting some uninitialised variables. While it only showed up in
AP_SbusOut, it means we can't be sure it won't happen on other objects,
so safest to remove the approach

Thanks to assistance from Lucas, Peter and Francisco
