Select the Enable secondary antenna check box to allow the configuration to be entered. If it
is not enabled, the RT1003 will ignore the secondary antenna and will not use it to compute a
heading solution.
By default, the
Antennas are level
box is checked. This means the antenna baseline should
be within ±5° of horizontal. When the antennas are level the separation should be measured
to within 50 mm. If the antennas are not level, i.e. mounted with height offsets or on an
incline, then the box should be unchecked. In this case, the separation should be measured to
within 5 mm.
Enter the antenna separation and select the position of the secondary antenna relative to the
primary antenna from the drop-down list. The measurement accuracy can also be specified
with the to within drop-down box. The illustrations will change according to the settings you
choose to help visualise the configuration of the antennas.
It is important to measure between the same point on each antenna, e.g. centre to centre, or
from cable to cable.If the antennas are mounted at significantly different heights, or if the
mounting angle is not directly along a vehicle axis (forward or right), then click

The Enable static initialisation option is useful for slow moving vehicles or when dynamic
initialisation may be difficult. Static initialisation is 99% reliable in open sky, but the
reliability decreases in environments where obstructions to GNSS signals are present. Static
initialisation is also faster when the antenna separation is smaller and the Antennas are level
check box is ticked.
