Andrew Tridgell 4f0a573c73 AP_AHRS: don't reject airspeed using EKF if dead-reckoning
when dead-reckoning the EKF wind estimate can diverge from reality,
leading to us rejecting a valid airspeed sensor. We are best off
trusting airspeed if we are dead-reckoning

Peter Barker 7fa0b75d48 AP_AHRS: 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 f933f148ed AP_AHRS: always run external AHRS arming check if enabled 2023-01-03 10:32:20 +11:00
Andrew Tridgell 87b4b031bf AP_AHRS: if DCM has no yaw source then don't fallback when hovering
this copes with quadplanes with no compass. With a compass we are
better off using EKF when not in fly-forward as it will give better
height control.

This makes QHOVER for takeoff in quadplanes with no compass a lot more
flyable

Andrew Tridgell 56c8cffc07 AP_AHRS: auto-enable EKF3 for misconfiguration
this fixes a "climb away" in quadplanes when AHRS_EKF_TYPE=2 and
EK2_ENABLE=0. The user has ARMING_CHECK=5390 to disable key arming
checks, and the plane flew on DCM as the configured EKF wasn't
enabled.

This resulted in AHRS::get_origin() returning false as it couldn't ask
EKF2 for the origin (as EKF2 was not enabled or instantiated)

The result was an incorrect calculation for target height during the
descent stage of QRTL, resulting in a climb away until the user took
over

Andrew Tridgell 924759510d AP_AHRS: fixed use of filtered gyro with DCM active
we need to overwrite _omega with the filtered gyro value, so we get
both the low pass filter and the notch filters. Otherwise we will fly
with very high noise gyro data

this also fixes the accel_ef_blended to use the filtered accel. It is
not blended, and removing "_blended" from the API will be worthwhile
as a followup

nrt c3d8f0fa45 AP_AHRS: added a getter function to get active source set once the ekf3 filter is started 2022-08-18 02:05:27 -04:00
Peter Barker 4139b7a548 AP_AHRS: rename OpticalFlow class to AP_OpticalFlow
Brings us in-line with other classes in ArduPilot.

Removes ambiguity with AP_HAL::OpticalFlow which can cause compilation errors as we start to make code more portable across targets

Peter Barker fd666dc4f1 AP_AHRS: subtract accel bias from correct ins accel instance
In the case that you have INS_USE indicating IMUs should be used, but
EK3_IMU_MASK leaving some IMUs unused, we subtract the bias from the
wrong INS data
