3458962184 GPS: test the more modern MTK16 2012-06-27 16:01:50 +10:00

426006d98f SITL: fixed GPS heading in simulated UBlox 
longitude scale does not apply to velocity->heading conversions
 2012-06-27 16:01:50 +10:00

20c1baf585 SITL: changes UBlox simulation to 5Hz 
this matches the real UBlox driver

d9583ae5eb 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.

5370f9c411 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
53e950531e 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

9fd3d15026 Filter: added 5 point average float filter 2012-06-27 16:01:50 +10:00

1ff9461bfb 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

73faaddc1b 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

ae9883a8e2 GPS: fixed auto-config of UBlox setup with no UBX messages 
if a UBlox is configured for NMEA only, with no UBX messages at all
then it would never trigger the GPS_AUTO detection. This adds a UBX
config message to the init strings that enables the NAV_SOL message

Andrew Tridgell
ddebf7b443 GPS: fixed the UBLOX parser to handle unknown messages 
the parser was broken in several ways:

 1) when it received an unknown message it didn't update the ck_a and ck_b fields, so it
    thought the message had a bad checksum, which meant it got out of protocol sync

 2) the read() method would return false if the last message from the GPS was of an unknown type. 
    So we relied on the last msg always being one that we understand and want

 3) the parser considered any valid UBLOX message to be 'new data', whereas we only actually get 
    a new fix when we get box a new position and velned message

 4) the total message size per update is more than 128 bytes, but the serial port was opened 
    with only a 128 byte buffer, so we got corruption regularly

8f27297896 DCM: fixed a bug when using GPS for yaw correction

6d837891b0 DCM: buffer omega_I changes over 10 seconds 
this buffers up _omega_I changes in _omega_I_sum over a period of 10
seconds, applying the slope limit only when _omega_I_sum is
transferred to _omega_I.

The result is a huge improvement in the ability of _omega_I to track
gyro drift over the long term.

398a608b83 DCM: drop the 'drop z' method 
the 'drop z' method reduced the impact of noise on omegaI, but it also
made us more sensitive to errors in accelerometer calibration and
scaling, as demonstated by the logs from Gabor here:

  http://diydrones.com/xn/detail/705844:Comment:834373

Simulation testing shows that the other noise suppression methods
applied in the DCM code, in particular the slope limiting on omegaI
the removal of the weighting and the upcoming use of a _omega_I_sum
buffer have reduced the impact of noise enough that we can now safely
include z in the acceleration calculation.

71ad185238 ArduCopter - AP_Motors library - added new library which has few advantages over current code: 
1. it's step towards rearchitecting the current code base ahead of a move to RTOS.
     2. internally it uses a MatrixTable for the Quad, Octa, OctaQuad, Y6 frames.
     3. it implements the missing stability patch for Octa and OctaQuads (still missing for Y6)

Later check-ins will incorporate into the main ArduCopter code.

e99d26cfa3 AP_Declination: The exception signs unpacking logic was incorrect. I was shifting a 1 value left y%8 which would have needed a the signs to be packed right to left.

Adam M Rivera
719636d00c AP_Declination: Reduced the size of the lookup table to support -75 <-> 70 latitude range. This allows the datatype to remain int8_t. 2012-03-30 14:21:57 +11:00

071f89df2e AHRS: fixed error_yaw reporting with 2 MAVLink connections 
when a user first connects with USB, and later switches to the

This ensures we give the last value after the counter is reset
