Wheel Speed Input
The RT can be factory configured to include a wheel speed input. This reduces the drift in
outputs when GNSS is not available. It is essential to use the Lateral and Vertical No-slip
slip features at the same time as wheel speed corrections.
As with the Lateral No-slip feature, the wheel speed input can only be used on land
vehicles; aircraft and marine vehicles cannot use this option. The wheel speed must not be
used on a steered wheel, it must be used on a wheel that is measuring the forward direction
of the vehicle.
Figure 34 shows the wheel speed configuration window. To enable the wheel speed input,
ensure the checkbox is checked. If this option is disabled, the RT will ignore corrections
from the wheel speed even if it is connected.
