Peter Barker 12a06ee0ae AP_AHRS: make a pair of methods static on AP_AHRS_Backend 
these don't use any information from the specific backend, but they are called within the backends so making them static on that class is handy
 2023-09-19 13:20:15 +10:00
Peter Barker a5bfd58524 AP_AHRS: remove un-needed AP_AHRS_Backend::getCorrectedDeltaVelocityNED 
over-kill, and can be derived from backend biases if required
 2023-09-19 12:51:31 +10:00
Peter Barker c30bceb2a0 AP_AHRS: return location inside backend_results structure 
with the change to cache results inside AP::ahrs().state we no longer need to worry about the backend's attempts to project the last-known-location forwards according to amount of time elapsed since that last-known-location was calculated.

Peter Barker 904707de15 AP_AHRS: clarify get_vert_pos_rate AHRS method name to include 'D' 2023-06-06 20:09:28 +10:00
Henry Wurzburg 3a49804703 AP_AHRS: fix compile for 1MB bds using SITL on hdwr 2023-05-16 21:11:36 +10:00
Peter Barker f67f025c92 AP_AHRS: pre-declare Location object 
we don't need to know the storage, and if you cut enough stuff out then we don't end up transitively including the required header for this.

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
 2023-02-04 22:51:54 +11:00
Peter Barker aa7ab28969 AP_AHRS: add a bool wind_estimate(...) 
NavEKF3 can fail to return a wind estimate, and we lose that value
 2023-01-18 11:20:32 +11:00
Peter Barker c42754b691 AP_AHRS: create an AP_AHRS_SIM backend 2023-01-12 13:11:40 +11:00
Andrew Tridgell f80ba734c8 AP_AHRS: removed use of "blended" accel values 
calculate a single EF accel based on primary IMU
 2022-08-21 18:51:59 +10:00
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
 2022-08-18 14:24:01 +10:00
Peter Barker cfb391dc2c AP_AHRS: stop using GCS_MAVLINK.h in header files 
... by passing through a reference to a link object instead
 2022-08-16 09:45:51 +10:00
Peter Barker 24099f9a2d AP_AHRS: include cleanups 2022-03-01 11:21:33 +11:00
murata 819b25d918 AP_AHRS: remove duplicated words from comments 2022-02-07 08:24:14 +09:00
Peter Barker ff63b62b0c AP_AHRS: rename AP_AHRS::get_position to get_location 2022-01-25 10:47:22 +11:00
Joshua Henderson 8a6942a9df AP_AHRS: add define AP_AIRSPEED_ENABLED 2022-01-19 18:21:32 +11:00
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 44d56854be AP_AHRS: make AP_AHRS_DCM an AP_AHRS backend 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
Randy Mackay 1c08866342 AP_AHRS: add using_extnav_for_yaw 2021-08-31 09:20:17 +10:00
Randy Mackay e7be608a4a AP_AHRS: rename is_ext_nav_used_for_yaw to using_noncompass_for_yaw 2021-08-31 09:20:17 +10:00
Peter Barker 9114d4fc86 AP_AHRS: make home-relative functions AHRS-frontend only 2021-08-25 18:32:07 +10:00
Peter Barker e2722c8e12 AP_AHRS: move active_accel_instance into DCM private header section 2021-08-24 10:23:36 +10:00
Peter Barker d6c7c59199 AP_AHRS: remove custom_rotation matrix to frontend 
Only one of these per vehicle
 2021-08-24 10:23:36 +10:00
Peter Barker 645a5302d0 AP_AHRS: move DCM parameters into DCM header 2021-08-24 10:23:36 +10:00
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
Peter Barker 8daa0a099c AP_AHRS: rename yaw_initialised access method to dcm_yaw_initialised 
This is what it really means.

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 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 e9c56a2b0a AP_AHRS: move takeoff/touchdown flags to frontend 2021-08-11 18:45:34 +10:00

Peter Barker ca58aa9c5f AP_AHRS: stop using AHRS as conduit for Compass pointer 2021-07-30 12:19:42 +10:00
Peter Barker e4bceb2417 AP_AHRS: move AOA/SSA to AP_AHRS, don't recalc on fetch 2021-07-30 11:23:06 +10:00
Peter Barker 5160b4f6ca AP_AHRS: move AP_NMEA_Output to AHRS frontend 2021-07-27 16:55:35 +10:00
Peter Barker 88d49effe7 AP_AHRS: move variable init into variable declaration 2021-07-23 09:55:14 +10:00
Peter Barker 15e5831002 AP_AHRS: remove unused get_expected_mag_field method 
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 
This is constant and is just folded into whereever it is used.
