Antenna pointing requires the use of several tools, as described in the following
sections.
Global Positioning System (GPS) receiver
Use a GPS receiver (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.
Your GPS receiver must be accurate to within 15 m. Most commercially available
receivers meet this requirement. Units employing Wide‐Area Augmentation System
(WAAS) technology provide accuracy to 3 m.
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 (satellite modem), then you will use a standard Internet browser
(Internet Explorer version 8 or higher, Mozilla Firefox 3.6 or higher, and Google
Chrome version 17 or higher) to navigate to the LUI. See Entering installation
parameters on page 11 for the exact procedure.
DiSEqC Antenna Pointing Tool (DAPT2)
The DAPT2 is a two‐way digital satellite equipment control (DiSEqC) tool. It has a
large backlit display and three buttons that enables the installer to step through the
