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

Andrew Tridgell ccc1f906f8 AP_NavEKF2: fixed EKF compass switching
when we had 3 compasses the lack of the 'break' meant when we switched
compass in flight we would always switch back instantly to the one
that we had just rejected.

Peter Barker 1c1d651979 AP_NavEKF2: add space for null-termination
This is simply to preserve existing behaviour when snprintf starts to
null-terminate strings

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.

Peter Barker 3774aa6619 AP_NavEKF2: remove default clause in setAidingMode
All values from the enumeration should be handled in this switch; adding
a default will hide a compiler warning which may be useful.
