Determine a location for the Dish.
The first step in selecting a mounting site for the dish is to approximate the location
of the DSS satellites in the sky. Then, select mounting site options that have the best
possible view. Finally, select the best mounting location from the possible sites.
To determine the satellite's position in the sky, first determine the side to side
(azimuth) and the up/down (elevation) bearings from your location to the satellites.
These change with different locations across the United States. For example, the
azimuth and elevation for Seattle, Washington are different than those for Syracuse,
New York.
The differences in azimuth and elevation between Seattle and Syracuse are due tothe
DSS satellite's position in the geostationary orbit. As stated earlier, the DSS satellites
are located over the equator at 10I* west longitude. As an installation site moves north
(away from the equator), the elevation of the dish lowers (towards the horizon) to point
it atthe DSS satellites. The azimuth of the dish also changes as you move either east
