Mounting location

2.3.1
This section provides information on determining the best location for
the sensor.
NOTICE!
The sensor should be mounted as low as possible while still maintaining
good sky visibility. This will reduce false movement due to the boat
rocking back and forth.
GPS Reception
When considering where to mount the sensor, consider the following GPS
reception recommendations:
• Ensure there is a clear view of the sky available to the sensor so the GPS
and SBAS satellites are not masked by obstructions that may reduce
system performance.
• Mount the sensor as close to the center of the vessel as possible. This
includes both the fore-aft direction and the port-starboard direction.
• Locate any transmitting antennas away from the sensor by at least several
feet to ensure tracking performance is not compromised, giving you the
best performance possible.
• Make sure there is enough cable length to tie into the Optimus CAN2 or
CAN3 backbone of the vessel.
• Do not locate the antenna where environmental conditions exceed those
specified in the table 2-1 Environmental Conditions below.
Environmental considerations
The sensor is designed to withstand harsh environmental conditions;
however, adhere to the following limits when storing and using the sensor:

VHF interference
VHF interference from devices such as cellular phones and radio
transmitters may interfere with GPS operation. For example, if installing the
sensor near marine radios consider the following:
• VHF radios can interfere with GPS signals.
• Follow VHF radio manufacturers' recommendations on how to mount
their radios and what devices to keep a safe distance away.
Before installing the sensor use the following diagram to ensure there are
no nearby devices that may cause VHF interference.
