Peter Barker ce04d69d53 AP_NavEKF3: correct compilation in SITL when logging is disabled 
this code is gated on HAL_BOARD_SITL already, and usually we have logging in SITL.  But not always

Marek S. Lukasiewicz 07681416f5 AP_NavEKF3: Match handling of MAV_CMD_EXTERNAL_POSITION_ESTIMATE to common MAVLink dialect 2024-03-07 18:13:51 +11:00
Peter Barker 21edc6aee1 AP_NavEKF3: do not trust number of beacons to not change 
if the count from the beacon library changes we may end up looking at memory we shouldn't
 2024-02-28 18:37:42 +11:00
Peter Barker a517d5fed1 AP_NavEKF3: correct initialisation of BeaconFusion data structure 
the fusionReport object is not being cleared when the filter undergoes a forced reset.

So delete and recreate the object.  Will also make this sensitive to the number of beacons changing.

Also don't attempt to allocate zero bytes.

Peter Barker 2df3cb98c6 AP_NavEKF3: move initialisation of rngBcn into BeaconFusion method 2024-02-27 12:04:14 +11:00
Peter Barker e9d065c1cc AP_NavEKF3: tidy population of fusion reports

Peter Barker 10c8af3409 AP_NavEKF3: do not use fmaxF on floating point values

Andrew Tridgell 484312df93 AP_NavEKF3: fixed race condition in updateFilterStatus() 
filter status was initially set to zero then updated. This interacts
with the IMU filtering code which checks filter status from a
different thread to determine active_EKF_type(). When the race
condition is hit then the IMU we are running notch filters on changes
for a single sample, causing a notch filter glitch

Andy Piper 2f97a9855a AP_NavEKF3: fix docs on ABIAS_P_NSE_DEFAULT 2023-07-14 08:33:05 +09:00
Andrew Tridgell d11d4fa0bf AP_NavEKF3: fixed velocity reset on AID_NONE 
The ResetVelocity() function is only supposed to reset XY states, not
Z state. Resetting the Z state for velocity results in a large
velocity glitch if a vehicle is descending or ascending when aiding
switches to AID_NONE

this fixes #19386

Peter Barker 35a5a73f52 AP_NavEKF3: avoid using struct Location 
clang reports this could be a problem when compiling under some EABIs.  Remove it from most places as it is just noise, replace with class where we want to avoid including Location.h

Peter Barker da95985dd7 AP_NavEKF3: remove mag_state state 
we don't need to persist this across multiple calls as we now fuse all axes on the one step.

Andrew Tridgell 92f25150f6 AP_NavEKF3: fixed getLLH alt for local origin height 
this fixes a bug introduced in #21834

this fix in #21834 was correct for getPosD, but should not have been
applied to getLLH

this caused cruise mode in plane to descend/ascend by the difference
between the public and local origins on mode entry

fixes #21984

Peter Barker 0665f9c32b AP_NavEKF3: store and use lastKnownPositionD 
When returning our last-known-position we were supplying lat/lng but not
altitude.

This usually really doesn't matter as this result generally isn't used,
especially for altitude.  OTOH, it may prevent a bug into the future.

Peter Barker 0b16c4063e AP_NavEKF3: stop libraries including AP_Logger.h in .h files 
AP_Logger.h is a nexus of includes; while this is being improved over
time, there's no reason for the library headers to include AP_Logger.h
as the logger itself is access by singleton and the structures are in
LogStructure.h

This necessitated moving The PID_Info structure out of AP_Logger's
namespace.  This cleans up a pretty nasty bit - that structure is
definitely not simply used for logging, but also used to pass pid
information around to controllers!

There are a lot of patches in here because AP_Logger.h, acting as a
nexus, was providing transitive header file inclusion in many (some
unlikely!) places.
