Antenna Setup Choosing the Appropriate Baseline Length
In theory, the baseline length (i.e. the horizontal distance
between the phase centers of the two GNSS antennas used,
also called antenna separation) can be set between
5 centimeters and 1,000 meters.
In practice, you will choose the baseline length taking into
account the level of expected accuracy as well as the various
installation constraints in the vehicle.
The chart below shows the expected heading accuracy for a
baseline length ranging from 30 centimeters to 150 meters.
