Paul Riseborough 7687a30c5f AP_NavEKF3: Allow operation with EK3_SRCx_POSZ = 0 (NONE) 2023-10-13 16:26:01 +09:00

Paul Riseborough 31d510042f AP_NavEKF3: increase innovation variance instead of clipping innovations 2023-09-05 19:40:15 +09:00
Paul Riseborough 7a4acadc9f AP_NavEKF3: Provide option to clip velocity and position innovations 2023-09-05 19:40:15 +09:00
Andrew Tridgell 9fc8078df4 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 168756ce76 AP_NavEKF3: fix docs on ABIAS_P_NSE_DEFAULT 2023-08-01 16:48:42 +09:00
Andrew Tridgell 1d686ff806 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

Paul Riseborough d98a60c2e1 AP_NavEKF3: Increase delta velocity bias state process noise
Required due to state variance collapse on ground with some systems using RTK GPS.

Paul Riseborough 17003ff0f5 AP_NavEKF3: Increase default value of EK3_ABIAS_P_NSE
This is required because some hardware setups with RTK GPS have experienced a collapse of the delta velocity state variances.

Peter Barker 2af6a05fa2 AP_NavEKF3: include writeWheelOdom symbol even if no body-odom
like the method above it, we need this symbol or we won't compile

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.

I've moved the defintion of these variables to where they are initialised to make it clear they're not used uninitialised.

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

Paul Riseborough 608b4c0713 AP_NavEKF3: Enable monitoring of unhealthy airspeed sensors
Innovations and innovation test ratios will still be calculated and reported for an unhealthy sensor, but the EKF states wnd covariance matrix will not be modified.

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.
