Andrew Tridgell	4f871c87f1	AP_AHRS: detect and try to cope with bad accels	11 years ago
Andrew Tridgell	02d6f012ce	AP_AHRS: added accel sum delay buffer to account for GPS lag	11 years ago

Andrew Tridgell	31eaaada62	AP_AHRS: removed vertical G limit on GPS velocity correction ... this limit could lead to a bias in the accel drift correction, and is frequenctly exceeded	11 years ago

Andrew Tridgell	7d42a0562d	AP_AHRS: cope better with large GPS yaw changes ... this should cope better with bungee launches when using only GPS for yaw.	12 years ago
Andrew Tridgell	14628990e6	AP_AHRS: make wind estimation configurable ... rover doesn't want it	12 years ago
Andrew Tridgell	6f1cee6406	AP_AHRS: fixed position estimate with 2D fix or low satellite count ... we should still use the GPS for position fixes when we have a low number of satellites, but we should stop using it for velocity estimates and attitude correction.	12 years ago
Randy Mackay	ceda7d26b0	AHRS: add correct_centrifugal and flags structure	12 years ago
Andrew Tridgell	38fc0e61c6	AP_AHRS: optimise yaw drift correction ... use new vector2 cross product, and factor out the z component of a dcm mul_transpose() to reduce the number of floating point operations for a yaw drift correction cycle	12 years ago
Randy Mackay	ee2daf25b6	AHRS: perf improvement by caching declination vector	12 years ago
Andrew Tridgell	943a1d8c8d	AP_AHRS: added AHRS_GPS_MINSATS option ... if the number of visible satellites is below AHRS_GPS_MINSATS then don't use the GPS for acceleration correction for attitude	12 years ago
Andrew Tridgell	ba83950fc4	libraries: replace constrain() with constrain_float() ... this makes the type much more obvious. Thanks to Tobias for the suggestion.	12 years ago
Andrew Tridgell	f5d6fb6216	AP_AHRS: added _kp gain reduction for catapult launch ... this should reduce the tendency of aircraft to nose down hard on initial launch at high g	12 years ago
Andrew Tridgell	fd2cd0d1c2	DCM: fixed formatting	12 years ago
jschall	610069e729	DCM: fixed airspeed bug ... we incorrectly went via the wind estimate when we had a working airspeed sensor	12 years ago
Andrew Tridgell	a4d25f5a82	AHRS: removed AHRS_BARO_USE option ... this option has caused users too much trouble. The vertical velocity is too noisy from the baro	12 years ago
Andrew Tridgell	8459da202c	AP_AHRS: prevents compass flyaways for plane and rover ... this switches to the GPS for yaw if the compass has dragged us off by more than 45 degrees from the GPS heading, and the wind speed is less than 80% of the ground speed.	12 years ago
Randy Mackay	24044dc0c4	AHRS: add support for GPS fix type 2D	12 years ago
James Bielman	5631f865b2	Update floating point calculations to use floats instead of doubles. ... - Allows use of hardware floating point on the Cortex-M4. - Added "f" suffix to floating point literals. - Call floating point versions of stdlib math functions.	12 years ago

Andrew Tridgell	fe47990dab	AP_AHRS: removed the 6 sats min ... this would put us into dead-reckoning mode	12 years ago
