SDT16 Family Installation and Configuration Guide
Chapter 2. Installation 25
I
MPORTANT
:
The location you plan to install the satellite terminal should provide a clear
path to the satellite. The path should be clear of all obstructions such as buildings, trees,
and hills. The satellite terminal should be located at least 6-
½
feet from objects taller than
1-
¾
feet in the direction of the satellite. The path to the satellite must be clear of all
obstructions otherwise satellite communications will be impaired. To get a signal, the
satellite terminal must be pointed in the direction of the satellite with no obstructions
between the two.
4. ORB Units (ORBCOMM):
For the SDT16-ORB:
a.
Use the information in ORBCOMM Satellite Service on page 21 to determine which
ORBCOMM GES is closest to the installation site.
b.
The location you plan to install the external antenna should be clear of all obstructions
such as buildings, trees, and hills. The antenna must have a clear line-of-sight facing in
the same direction as the nearest ORBCOMM GES. The antenna must also be installed
at least two (2) feet above the solar panel to prevent signal interference during data
transmissions.
c.
Begin the installation with Mounting Requirements on page 28.
Determining the Satellite Look Angle (SAT Only)
If you plan to install the SDT16-SAT Bullhorn units outside the United States, use the following
information to determine the correct satellite look angle (azimuth and elevation coordinates) for
the location you plan to install the satellite terminal. If you plan to install the Bullhorn unit in the
United States, skip this section and continue with
Confirming the Satellite Look Angle (SAT Only) .
Complete the following steps:
1.
Log on to your Bullhorn website account at:
http://www.bullhornsys.com
2.
On the main window, click
Help
and then
Coverage Maps
. Click the
SkyWave Inmarsat
Satellite network
link to view the map.
3.
As you move your mouse over the map, place the mouse over the location you plan to
install the Bullhorn unit.
Look angle coordinates display under the cross hair cursor. The azimuth and elevation
angle display under each satellite that provides coverage. A green colored satellite indicates
good coverage, yellow indicates coverage but at a low elevation angle, and gray indicates no
coverage.
4.
Record the look angle coordinates. Use the coordinates when completing the procedure in
the next section.
