1.6. Functional Diagram
Signal paths are show in the functional diagram below.
1.6.1. Mount Orientated Signals
Note that the
Yaw, Pitch, Roll, Quaternion
, and
Gravity Vector
are
compensated
for the
selected Mount
Orientation
.
1.6.2. Enclosure Orientated Signals
The outputs of the
gyroscope
,
accelerometer
and
magnetometer
are
not
compensated
for the
selected Mount Orientation
.
These signals are biased/calibrated to canonical units.
(Note 1)
.
As a result, these signals are
referenced
to the
enclosure’s orientation
.
If these
enclosure-oriented signals
are used, it is recommended to choose a
Mount Orientation that is reasonably horizontal or vertical so that Yaw, Pitch,
Roll, and Gravity Vector are also aligned to these signals.
Note 1:
Magnetometer requires user calibration
