1.4. Heading Configuration
The heading result is the angle from True North to the baseline of the base to
rover in a clockwise direction. Receivers(UB482&UM482) supports heading output by
default. Frequently used commands are as follows:
MODE HEADING
GPHDT COM1 1
SAVECONFIG
1.5. Inertial Navigation
High-precision boards have built-in inertial navigation devices.Please refer to
Figure 1-1: Vehicle Coordinates （ XYZ ） to set the installation angle.
The boards’ inertial coordinate system, X, Y, Z axis are mutually perpendicular,
follow the right-hand rule.
The vehicle coordinate system is defined as follows: the Y axis along the vehicle’s
travel forward direction, the X axis perpendiculars to the Y axis and points to the right.
Ensure boards’ inertial coordinate system match with the vehicle’s coordinate
system.
