● The GNSS antenna should be located where it has a clear,
unobstructed view of the sky overhead.
● The GNSS antenna should be mounted as high as possible, however
it is not recommended to mount the antenna on the top of a high mast
where the motion of the vessel will cause the antenna to move and
potentially reduce the accuracy of the GNSS position.
● Route the GNSS antenna cable to the AIS transceiver. If extension
cables are required all junctions should be made using appropriate
co-axial connectors and made watertight.
Connect the GNSS antenna cable to the GNSS connector on the AIS
transceiver.
Figure 7 GNSS Antenna location
GNSS Antenna should be at least 5m (16ft)
from radar or satellite communication
antennas. It should also be away from
the radar beam path and mounted
on a rigid surface.
