Azimuth Offset, Antenna Setup & Resulting Heading
Consider the following four setups before installing your
antennas. A vessel 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.
Delivering an RTK Position for the Primary Antenna
There may be an additional requirement you should take into
account when setting up your antennas for heading
measurements, which is the fact that your application may
also require that the receiver deliver an RTK solution of
position for the primary antenna. In this case, the absolute
location of the primary antenna in the vehicle is probably
critical and this will impact the location of the secondary
antenna as well.
