Heading
Configuration
Description
Pitch/Roll Mode
If the antennas are mounted such that they
model pitch, set to PITCH.
If the antennas are mounted such that they
model roll, set to ROLL.
Note:
If your HBIAS is -90 or +90, set this to
ROLL. If your HBIAS is 0 or 180, set this to
PITCH.
Heading TAU
Adjust the responsiveness to true heading.
If the machine is large and unable to turn
quickly, increase this value.
For longer baselines (10 m) HTAU should be
between 0.1 and 0.5, since the gyro
introduces noise.
Default value:
0.1 s with gyro enabled
Range:
0.0 to 60 s
Formula:
htau (s) = 40 / max rate of turn
(°/s)
with gyro ON
htau (s) = 10 / max rate of
turn (°/s)
with gyro OFF
Heading Rate TAU
Adjust the responsiveness to the rate of
heading change.
If the machine is large and unable to turn
quickly, increase this value.
Default value:
2.0 s with gyro enabled
Range:
0.0 to 60 s
Formula:
hrtau (s) = 10 / max rate of the rate
of turn (°/s
