GMM-NT (MG-Navtracker) - Installation Guide
Antenna Location Considerations
·
Think Security. The location of the antenna is
critical to proper system operation and should be
toughly scrutinized.
·
The antenna is able to penetrate up to ½ inch of
solid fiberglass, making way for covert installs.
·
Locate the antenna a minimum of two feet away
from metallic obstructions such as hand rails, rod
holders and cleats.
·
Choose a location that is not directly under or near
radar arrays to prevent possible interferences.
·
Make sure that the underside of the antenna is
accessible to connect the antenna cable. Leave
approximately four inches directly underneath the
antenna to provide space for the connection.
·
Mount on a flat horizontal surface.
·
The antenna communicates its data to the
Inmarsat® Geostationary based satellite network.
As a general rule, a clear line of site towards the
equator is needed.
·
Center Consoles - It is suggested that the antenna
not be installed on T-Tops as they are more
vulnerable for tampering. Popular locations
include forward/aft stringers underneath the
gunwale. Keep away from midship gunwale
mounting as the T-Top could potentially block the
signal from getting out.

.
·
Larger vessels - Often require exposed hardtop or
arch mounting. A ¾ inch hole can be drilled and
sealed under the antenna with silicon.

·
Whenever possible, dry run the installation
procedure and test the location beforehand.

Voltage Requirements
The Nav-Tracker 1.0 will operate on either 12 or 24 VDC.
Power Consumption (typical@12V)
Receive 1.5W; Slotted receive 100mW; Transmit 5W
*Do not use a switched power supply that is
normally left off when the boat is idle.
Installation
1.)
Thoroughly read the Nav-Tracker antenna
location considerations and mount it according to
this criteria.
2.) Snake antenna cable from antenna to the control
unit and connect the pin arraignment according to
Figure 2+ 3.
3.)
Mount the control unit in a discreet and accessible
location.
4.) Connect the power cable to a co12-24
VDC and negative Ground. Then plug it into the
control unit.
5.)
Connect Antenna connection to the antenna.
6.)
There is a light at the base of the antenna
Figure

. Assure that the antenna is rotated to a position
where the light is visible to the installer.
When
the unit is first powered up it will initially blink
red, then gradually change to orange, and then
green. The antenna should be blinking green
within about five minutes of startup. If it does
not, confirm that the signal is not getting blocked
and adheres to the location considerations. Make
sure that the keyswitch on the control unit is left
in the 12 O’clock AutoArm position. (Figure 5).
7.)
Leave the antenna plugged in. Direct the owner
to the sticker at the bottom of the included user
guide to activate the antenna. Antennas that
remain unactivated for more than two weeks are
automatically sent a disable command. Re-enable
commands can be sent, though immediate
activation is suggested after installation.
