Choosing Component Locations
When determining component locations, first keep in mind
accessibility and cable lengths between units. For example, since
the data/power cable is 100 ft (30 m) long, the MCU must be
located within 100 ft (30 m) of the antenna.
The major considerations in locating the TracVision components
are described below.
Choosing the Best Location for the TracVision Antenna
There are several factors to consider when choosing the location
for the TracVision antenna.
•
Since the TracVision antenna requires a clear view
of the southern sky to receive satellite signals, the
ideal antenna site has an unobstructed view of the
horizon/satellite all around. The less blockage, the
better the system performs.
•
Keep the antenna clear of any obstructions above
decks. The antenna requires a -15º to +85º look
angle to receive satellite signals.
•
To minimize tracking errors, place the antenna
unit as close as possible to the intersection of the
vessel’s fore-and-aft centerline and midships. The
antenna unit need not be located exactly on the
vessel’s fore-and-aft axis, but its centerline MUST
be parallel to it.
