Note:
The V102 moving base station algorithm only uses GPS to calculate
heading. Differential corrections are not used in this calculation and will not
affect heading accuracy.
Supplemental Sensors
The V102 has an integrated gyro and two tilt sensors. The gyro and tilt
sensors are enabled by default. Each supplemental sensor may be
individually enabled or disabled. Both supplemental sensors are mounted
on the printed circuit board inside the V102.
The sensors act to reduce the RTK search volume, which improves heading
startup and reacquisition times. This improves the reliability and accuracy of
selecting the correct heading solution by eliminating other possible,
erroneous solutions. Table 3-1 on page 32 provides a sensor operation
summary.
