The non-alignment of the baseline with the vehicle centerline
may be intentional (see explanations in the next section
below).
Correlation Between Azimuth Offset, Antenna Setup &
Measurements Made
Consider the following four setups before installing your
antennas. A ship is shown in the examples but this could be
any other type of vehicle.
Depending on the type of measurements you wish the
receiver to perform (heading+roll or heading+pitch) and the
installation possibilities offered in the vehicle, you will
choose the most appropriate setup and set the azimuth offset
accordingly.
