Configuring Terrain Compensation - Novatel SMART2 Installation And Operation User Manual

Chapter 3 SMART2 Operation
If terrain compensation is enabled, the SMART Antenna determines the roll and pitch angles and corrects the
position data before it is forwarded to the user equipment. In the example shown in Figure 6: Terrain Com-
pensation – Roll on the previous page, the roll angle is 10 degrees, so the position correction that needs to be
applied is 61 cm. In the example shown in Figure 7: Terrain Compensation – Pitch on the previous page, the
pitch angle is 8 degrees, so the position error that needs to be applied is 49 cm.

3.6.1 Configuring Terrain Compensation

To fully install and set up Terrain Compensation:
1. Mount the SMART Antenna on the vehicle.
2. Measure and set the height of the SMART Antenna from the ground to the bottom of the antenna.
3. Level the tilt sensor.
4. Save the Terrain Compensation configuration data.
Mount the SMART Antenna
The SMART Antenna must be mounted as close to the center of the vehicle as possible, as illustrated in Figure
8: SMART Antenna Installation on the next page.
