ABSTRACT:
A receiver connected to the satellite dish antenna receives signals from an electronic compass for generating a magnetic direction signal. The approximate latitude and longitude values of the parked vehicle are displayed and the user of the system manually selects the latitude and longitude coordinates corresponding to the parked vehicle location. The receiver determines an initial search position for the satellite dish antenna based upon the magnetic reading and the entered latitude and longitude values. The satellite dish antenna is moved from an unstowed position to an initial search position. The satellite dish antenna is then moved in a first rectangular spiral search pattern to obtain a rough-tune position corresponding to the detection of a signal peak for a selected audio subcarrier frequency in a selected channel of a target satellite. The frequency selected is not present in corresponding selected channels of satellites near the target satellite. A fine-tune search is then performed and the method calculates all the azimuth and elevation positions of all remaining satellites.
