Andrew Tridgell 51080d3e9e AHRS: update example for new ins interface 2012-11-30 07:15:19 +11:00
Andrew Tridgell 1dad9e4e94 AHRS: improved some more doc strings 2012-11-27 15:56:53 +11:00
Andrew Tridgell eb1d5c2c68 AHRS: improved docs for AHRS_GPS_USE
some people are setting this to zero to prevent jitter, which results
in their plane flying off into the distance and never coming back
2012-11-27 15:41:52 +11:00
Andrew Tridgell 5a214acca3 AHRS: changed the docs for AHRS_YAW_P and AHRS_RP_P
a user had set AHRS_YAW_P to zero. Make it clear that zero is not a
good value. MichaelO will change MP to give a warning for a value
below 0.1

2012-11-06 14:26:49 +11:00
Andrew Tridgell 6a24bdec05 AP_AHRS: require at least 6 satellites to use the GPS for velocity
logs of a recent flight show the velocity estimate can be very poor if
the GPS can see 5 satellites or less

this allows APM to cope better with airspeed sensor failure, but
ensuring airspeed stays within AHRS_WIND_MAX of ground speed
2012-09-08 11:37:07 +10:00
Andrew Tridgell 2be785899b AHRS: added airspeed_estimate() function

Andrew Tridgell 6d28b3519f AHRS: removed AP_AHRS_Quaternion
this AHRS backend is causing compiler errors with the Arduino build
environment on windows. The quaternion AHRS backend is currently not
being developed/supported anyway. We can resurrect it if someone wants
to start developing it again.

Andrew Tridgell ac72db8f00 AHRS: added set_fast_gains() method
this will be used by arducopter on the ground
2012-08-21 15:38:06 +10:00
Andrew Tridgell 14cdbd36cb AHRS: check for bad values in the error before they can affect DCM
this should fix the DCM renorm errors in autotest, probably caused by
bad climb rates
2012-08-18 13:54:11 +10:00
Andrew Tridgell d9cc967508 AHRS: force an extra read of the compass on startup
the first read from the compass can be bad. This ensures we have a
good value when getting the initial AHRS yaw.

Thanks to Randy and Jason for the bug report!

Andrew Tridgell 73dcbc24c3 Quaternion: we no longer support acceleration in the GPS driver
remove the linear acceleration compensation code
2012-08-15 20:07:53 +10:00
Andrew Tridgell 9b4b7997b6 AHRS: added ahrs.yaw_initialised()

reliable yaw estimate
2012-08-15 12:39:34 +10:00
Andrew Tridgell 48e275e22d AHRS: avoid a compiler bug in quaternion code
Having _wind in the AP_AHRS class causes a register allocation error
when building the Quaternion code with some versions of avr-gcc. Quite
bizarre.
2012-08-13 11:08:10 +10:00
Andrew Tridgell 19a5d11669 AHRS: use airspeed for wind in forward flight
when not turning we can use the airspeed sensor directly to calculate
the wind speed.
2012-08-12 10:54:25 +10:00
Andrew Tridgell f5b7ae213c AHRS: added AHRS_GPS_USE parameter

allows for testing dead-reckoning
2012-08-11 22:06:03 +10:00
Andrew Tridgell 779dacfd24 AHRS: added wind estimation code
this allows us to estimate the wind while we have GPS lock, then use
that estimate in the long term dead reckoning
2012-08-11 22:06:03 +10:00
Andrew Tridgell af4071894e AHRS: added long-term dead-reckoning
this uses airspeed (if available) or last GPS ground speed to update
our position estimate in AHRS
2012-08-11 12:00:31 +10:00
Andrew Tridgell f95b06a880 AHRS: make airspeed sensor available to AHRS
