Pointing tools and
user interfaces
The antenna pointing process makes use of several tools that are
used both separately and together during the procedure. These
tools are described in the following sections:
Global Positioning System
(GPS)
Use a GPS (not supplied) to determine the exact latitude and
longitude coordinates of the antenna site. These coordinates are
used to determine the correct azimuth and elevation information
for the antenna to point at the satellite from its location.
Your GPS receiver must be accurate to within 15 meters. (Most
receivers on the market will meet this requirement. Units
employing Wide-Area Augmentation System [WAAS]
technology provide accuracy to 3 meters.)
The GPS must display latitude and longitude information in the
format DD MM.mmm, where DD = degrees, MM = minutes, and
mmm = fractional minutes (the unit must display fractional
minutes to three significant digits).
Local User Interface (LUI) The LUI is the satellite modem interface. It is used to enter
installation parameters required for pointing the antenna. The
LUI also displays the beacon signal strength for monitoring
purposes. To access the LUI, you must first connect your laptop
to the indoor unit (IDU), then you will use a standard Internet
browser (Internet Explorer 6 or higher, or Mozilla 1.8 or higher)
to navigate to the LUI. See
Entering installation parameters on
page 8 for the exact procedure.
DiSEqC Antenna Pointing Tool
(DAPT)
The DAPT is a two-way digital satellite equipment control
(DiSEqC) tool. It has a large back-lit display and three buttons
that enable the installer to step through the antenna pointing
procedure. Figure 1 shows the DAPT.
