Andrew Tridgell 27761737ce SITL: fixed GPS heading in simulated UBlox 
longitude scale does not apply to velocity->heading conversions
 2012-06-27 16:01:50 +10:00
Andrew Tridgell b811653800 SITL: changes UBlox simulation to 5Hz 
this matches the real UBlox driver
 2012-06-27 16:01:50 +10:00
Andrew Tridgell 5cd5f40f09 autotest: switch to full accel modelling in multicopter simulation 
the new AHRS code should allow for centripetal compensation in
multicopters

Andrew Tridgell d2e72171ab ArduTracker: update for new compass interface 2012-06-27 16:01:50 +10:00
Andrew Tridgell 2e951647c4 Rover: updates for new compass interface 2012-06-27 16:01:50 +10:00
Andrew Tridgell 33440567e6 ACM: ArduCopter updates for new compass interface 2012-06-27 16:01:50 +10:00
Andrew Tridgell 3a2594fa1a APM: ArduPlane updates for new compass interface 2012-06-27 16:01:50 +10:00
Andrew Tridgell e4d28b12e5 Compass: remove the need to call calculate() on the compass object 
the new AHRS code doesn't use calculate() and the compass.heading
attribute. Instead it works on the raw magnetometer vector. This
change removes the internal calculate state from the compass object
and instead adds calculate_heading() for use by older code that
doesn't go via AHRS.

This significantly reduces the calculation involved in compass updates

The null offsets enable/disable code is also removed, as it is not
needed now that compass offsets are not linked to the AHRS state.

Andrew Tridgell 3a41ad8e7c AHRS: normalize the ge vector in drift correction, and use barometer 
The normalisation ensures the error term scales uniformly with
different accelerations.

The barometer is used for vertical acceleration estimation
 2012-06-27 16:01:50 +10:00
Andrew Tridgell dae1a57dc5 ACM: adapt the ArduCopter code for new barometer interface 2012-06-27 16:01:50 +10:00
Andrew Tridgell 6639294c72 APM: update for new barometer interface 
the barometer can now calibrate and return altitude values.

A 0.3 low pass filter is used on altitude to match the previous code
 2012-06-27 16:01:50 +10:00
Andrew Tridgell c387edd74c Baro: added get_altitude() and get_climb_rate() interfaces 
this allows the barometer driver to calibrate and return altitude and
climb rate values. This will be used by the AHRS drift correction code
for vertical velocity

The climb rate uses a 5 point average filter
 2012-06-27 16:01:50 +10:00
Andrew Tridgell 06c8763881 Filter: added 5 point average float filter 2012-06-27 16:01:50 +10:00
Jonathan Challinger d230690b7b AHRS: brought DCM more inline with Bill's implementation 
omega_I applied continuously. _ki larger. Stop integrating when _omega.length()>20

The key change was the scaling of ge to ensure the error is not
quadratic
 2012-06-27 16:01:49 +10:00
Andrew Tridgell 2934b4173b APM: set_centripetal() is now set_fly_forward() 
this controls more than just centripetal correction
 2012-06-27 16:01:49 +10:00
Andrew Tridgell b676caa626 ACM: enable GPS in AHRS for ArduCopter 
this is an experiment in centripetal correction for multicopters
 2012-06-27 16:01:49 +10:00
Andrew Tridgell d4c8041c51 AHRS: first successful version of Bills new drift correction system 
This makes 3 major changes:

 1) fixes the scaling of the yaw drift correction term to fix the time
 constant

 2) don't integrate the mag vector over multiple readings

 3) accumulate omega_I changes over 15 seconds before applying, to try
 to prevent omega_I picking up short term responses
 2012-06-27 16:01:49 +10:00
Andrew Tridgell 4d08f75292 AHRS: update for new _fly_forward flag 2012-06-27 16:01:49 +10:00
Andrew Tridgell 0f5c22bd8e AHRS: implement Bills new drift correction algorithm 
this is an initial implementation of this paper:

used by AHRS for acceleration correction

save a bit more code space for larger functions
