Supplemental Sensors
Overview
The V200n has a supplemental sensor integrated into the H220 GNSS
board that is enabled by default. You can enable/disable the sensor.
The sensor acts 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.

the sensor status.
Tilt aiding
The V200n’ s internal sensor is factory calibrated and enabled by default
and constrains the RTK heading solution beyond the volume associated
with a fixed antenna separation.
The V200n knows the approximate inclination of the secondary antenna
with respect to the primary antenna. The search space defined by the
sensor is reduced to a horizontal ring on the sphere’s surface by reducing
the search volume and decreases startup and reacquisition times (see
Figure 4-1).
