Andrew Tridgell 304b7df8c2 AP_AHRS: make the EKF accel bias accessible 
needed for fixed wing yaw damper
 2021-12-07 17:05:54 +11:00
Peter Barker 66d8be825f AP_Logger: move LogOriginType into AP_AHRS 
only used to log the origins by the AHRS library

Peter Barker 1dd34d87e7 AP_AHRS: move LogOriginType into AP_AHRS

 2021-12-07 11:31:44 +11:00
Andrew Tridgell 0141ec5be7 AP_AHRS: fixed switching airspeed sensor based on EKF3 affinity 
we need to use the EKF selected airspeed sensor when the EKF is setup
to run a different sensor on each lane
 2021-11-24 13:52:13 +11:00
Andrew Tridgell 01fb16b3b0 AP_AHRS: relax arming checks for inactive AHRS types 
When using an EKF as ride-along we should not fail arming if it has
inconsistent yaw between its lanes. This is especially important when
using external yaw or GPS yaw with EKF3, where yaw is expected to be
bad with EKF2.

The check on DCM is based on the existance of an AHRS view. This is so
that tailsitters do not get arming failures due to the inability of
DCM to cope with being nose up
 2021-11-04 17:44:29 +11:00
Andrew Tridgell bdf903b862 AP_AHRS: add accessor for GSF yaw estimator 2021-11-01 09:00:27 +11:00
Andy Piper e1dd0fd70d AP_AHRS: convert APM_BUILD_COPTER_OR_HELI() to APM_BUILD_COPTER_OR_HELI 2021-10-26 11:42:12 +11:00
Peter Barker 43e83f18be AP_AHRS: do not send EKF_STATUS_REPORT from DCM 
This means that even if you configure DCM as your primary you won't get
its status.

Given the status was currently garbage, this isn't necessarily a bad
thing at the moment.
 2021-10-06 19:10:36 +11:00

Peter Barker 29d2eed9e4 Sub: view update does not take skip_ins_update 2021-08-31 14:28:53 +10:00
Peter Barker 9dbd9d1e06 AP_AHRS: call INS update in AP_AHRS::update w/o holding data sem 
We shouldn't be holding the data semaphore while waiting for the samples
- lots of things might be unnecessarily blocked

DCM's update function doesn't need to take the semaphore as it is
already taken by AP_AHRS
 2021-08-31 14:28:53 +10:00

fixes regression from d1d790019c
 2021-08-25 18:28:12 +10:00
Peter Barker a933652950 AP_AHRS: return perfect airspeed estimate for EKF-type 10 
... rather than the EKF3 estimate

Peter Barker 74709c6292 AP_AHRS: move groundspeed vector up to AP_AHRS_DCM 
The other estimators all have their own implementation of this
 2021-08-24 10:23:36 +10:00
Peter Barker 8169910866 AP_AHRS: move frontend parameters up / DCM parameters down 2021-08-24 10:23:36 +10:00
Andrew Tridgell 53e7436525 AP_AHRS: allow for fallback to DCM in quadplanes 
this adds the necessary functions to allow for flying a quadplane on
DCM as an emergency fallback. It sets the NavGainScalar to 0.5 to
reduce the VTOL controller gains to allow planes to cope with the
higher lag of DCM
 2021-08-19 14:42:28 +10:00
Peter Barker 5d49d29c27 AP_AHRS: move wind-estimation-enabled state to frontend 2021-08-18 18:37:39 +10:00

Also put the relevant state within the DCM object
 2021-08-18 18:37:39 +10:00
Peter Barker 608608f32f AP_AHRS: internalise application of correct_centrifugal 
This is a DCM-only option but that's not clear with the interface.
Internalise the variable and base it off build type.
 2021-08-17 10:36:46 +10:00
Peter Barker 1cfd9f57ce AP_AHRS: move VehicleClass handling to AHRS frontend 
.... and renaming the enumeration while we're at it
 2021-08-17 10:34:07 +10:00
Peter Barker 29aed55a74 AP_AHRS: remove pointless zeroing of gyro_estimate vector 
This value is assigned to in the following "if" block in both the for
and against cases, and isn't used to determine the new value.
 2021-08-12 08:52:24 +10:00
Peter Barker 73bad9fd2d AP_AHRS: move fly_forward flag to front end 
This same flag is requested by the DAL so AN_NavEKF2 and AP_NavEKF3 can
use it in their estimates - so AP_AHRS_DCM accessing it via the same
mechanism is not out-of-shape
 2021-08-11 15:36:22 -07:00

Peter Barker f557d41145 AP_AHRS: rotate quaternions into vehicle body frame 
DCM was having it both ways depending on whether it was
primary/secondary.

These are mostly uses for reporting, in which case you would expect the
quaternion to match the eulers.

there's get_mag_field_NED on AP_AHRS....
 2021-07-23 09:55:14 +10:00
Peter Barker 5b372dae06 AP_AHRS: stop storing gyro drift rate as variable

Peter Barker 814aa4e5ec AP_AHRS: take secondary attitude from EKF3 if it is configured 2020-11-10 10:59:08 +11:00
Iampete1 d7e8ad1c13 AP_AHRS: add ARSPD_OPTION note to WIND_MAX 2020-10-27 11:21:04 +11:00
Randy Mackay 6a72805f07 AP_AHRS: get_variances does not return offset 
the offset is not a variance and is not actually used by any callers of this function

Peter Barker d4cb14b262 AP_AHRS: remove magic resetting of EKF type 1 to 2 
If EKF2 is not compiled in the current compatability code will not work
so well.

Throw the user over to the config error loop and they can fix it there.

Also removes prearm_failure_reason

Andrew Tridgell a4e7c72635 AP_AHRS: removed duplicate implementation of airspeed_estimate() 2020-08-27 20:20:51 +10:00
Harshit Kumar Sankhla b5b3298f0a AP_AHRS: get airspeed estimate from non-primary instances too 
with multiple airspeed sensors and airspeed affinity in EKF3,
it is possible to have switched over to a lane not using the
primary airspeed sensor, so AHRS should know which airspeed
sensor to use, i.e, the one being used by the primary lane.

Andrew Tridgell e5e092d077 AP_AHRS: check EKF status for having horizontal position estimate 
this will allow a fixed wing to fall back to DCM if the EKF stops
providing an absolute position while we have 3D GPS lock. The
using_gps flag is not enough, as lagged GPS data can lead to the EKF
stopping fusing when the data is behind the fusion time horizon. In
that case EKF3 gives using_gps=1 but sets horiz_pos_abs=0

Andrew Tridgell 3f69f97d60 AP_AHRS: added get_accel() for lua access 2020-08-16 08:55:27 -07:00

Peter Barker ad435dcdbb AP_AHRS: remove unused base-class airspeed_estimate method 2020-08-04 10:08:22 +10:00
Andrew Tridgell d0d7a46492 AP_AHRS: fixed SITL origin handling 
we need to keep origin and home separate for AHRS_EKF_TYPE=10. This
caused issues with resets in RealFlight leading to the plane not
descending
