Peter Barker 10c8af3409 AP_NavEKF3: do not use fmaxF on floating point values 
it returns double, which will not fit into this float

Paul Riseborough 5aa7bd0b7a AP_NavEKF3: Allow operation with EK3_SRCx_POSZ = 0 (NONE) 2023-08-23 18:25:26 +10:00
Andy Piper c57efa1b20 AP_NavEKF3: allow high values of EK3_ALT_M_NSE for boards without baros 2023-08-23 18:25:26 +10:00
Paul Riseborough e3c0175bb4 AP_NavEKF3: Update EK3_GLITCH_RADIUS metadata 2023-08-16 17:56:43 +10:00
Paul Riseborough 842882355f AP_NavEKF3: increase innovation variance instead of clipping innovations 2023-08-16 17:56:43 +10:00
Paul Riseborough 573bd7c7f3 AP_NavEKF3: Provide option to clip velocity and position innovations 2023-08-16 17:56:43 +10:00
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

Paul Riseborough b1111e79fe 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.

bugobliterator deeeb4134c AP_NavEKF3: use INS_MAX_INSTANCES instead of MAX_EKF_CORES for IMU mask 2023-03-21 10:04:16 +11:00
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
 2023-02-11 10:36:33 +11:00
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

Iampete1 16b1bd8b9a AP_NavEKF3: pre-arm return failure message for correct core 2023-01-31 13:36:56 +11:00
Peter Barker 8a312d4f34 AP_NavEKF3: use classes to fix MATH_CHECK_INDEXES 2023-01-25 19:58:54 +11:00

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.

Peter Barker 806b2708c1 AP_NavEKF3: change namespace of MultiCopter and FixedWing params 
this stops the libraries knowing anything about AP_Vehicle

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

jackhong12 4a4f361a17 all: use CLASS_NO_COPY() macro 2022-10-04 11:23:04 +11:00

always use common origin, and adjust output posD for difference
between public and local lane origin heights

Paul Riseborough 399f30bfce AP_NavEKF3: Allow reporting of airspeed consistency for a deselected sensor 2022-09-26 14:17:53 +10:00
Paul Riseborough eb0e9230a1 AP_NavEKF3: Add accessor function for airspeed health monitoring 2022-09-26 14:17:53 +10:00
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.

Tamas Nepusz 8959d35b91 AP_NavEKF3: add EK3_GPS_VACC_MAX as a threshold that decides whether to use GPS as altitude source depending on vAcc 2022-08-03 17:57:05 +10:00
