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 fb176b544f AP_NavEKF2: correct compilation when running MATH_CHECK_INDEXES 2018-10-19 08:46:43 +11:00
Peter Barker 889190d46e AP_NavEKF2: always set EKF control limits, even with no cores 2018-10-09 10:47:38 +11:00
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.

const some of the vectors, stop taking references to scalars that aren't
being changed

Randy Mackay 3d72022f6e EKF: modify ALT_SOURCE param description 
We regularly find users changing the ALT_SOURCE to 1 (range finder) when trying to implement terrain following which is not the correct way to do it

Peter Barker dbe860152d AP_NavEKF2: tight types on constants 
This saves ~200 bytes on at stm32 build, at the expense of people having
to watch the type carefully when increasing the values
 2018-03-01 20:27:19 +09:00
Peter Barker 3a99b2bce1 AP_NavEKF: move initialisation of EKF constants into header file 
Various comments where getting out of sync with one-another, and
having everything in one place lets you match values against types.

Pierre Kancir 171e80d8dc AP_NavEKF2: only report terrain estimator innovations with valid rng value 2017-12-18 22:51:46 +00:00
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

Andrew Tridgell 97729a12f0 AP_NavEKF2: don't run IMU updates until buffer fills 
this prevents us using bad initial data multiple times. It fixes a bug
where the IMU may pause during EK2 initialisation

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 ac568bae53 AP_NavEKF2: Initialise EKF origin height to field elevation 
Enables copters to set bit position 2 in the EK2_OGN_HGT_MASK parameter without having a large jump in reported local position height.
 2017-07-17 02:22:02 +01:00
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.
