The terminal may be slightly misaligned with the aircraft roll, pitch or yaw axes as shown below in Figure
4-7.

The installation offset angles must be compensated for by the terminal to ensure optimal system
performance.
Mounting the terminal as level as possible ensures the terminal has a symmetric view of the satellite.
Perform the following steps to measure and configure the installation offset angles:
1. Measure the roll, pitch and yaw offsets using a clinometer with measurement accuracy of better
than 0.25°.
2. Roll and pitch attitude offsets of the antenna can be determined by subtracting the aircraft attitude
angles from the terminal attitude angles.
3. Measure the aircraft attitude angles with the clinometer on an appropriate reference surface.
4. Measure the terminal attitude angles with the clinometer placed on the terminal mounting surface.
5. Measure the yaw installation offset angle using an accurate compass or protractor with reference to
the centreline of the aircraft.
6. Programme these values into the UAV 200 terminal using the Web Interface DASHBOARD.
