Abstract:
A method of adjusting an antenna on a radio receiver with respect to a satellite comprising the steps of:selecting a first range of elevation angles of said satellite with respect to said radio receiver to correspond to a low elevation angle; selecting a second range of elevation angles of said satellite with respect to said radio receiver to correspond to a high elevation angle; selecting at least first and second antenna array patterns for providing different array phasing data to a plurality of antenna elements associated with the antenna depending on which of said first and second antenna array patterns is used to adjust said antenna, said first and second antenna array patterns being selected to optimize reception of said radio receiver when characterized, respectively, as having one of said first range of elevation angles and said second range of elevation angles; determining if the elevation angle of said satellite with respect to said radio receiver at each of selected geographic areas in the operating area of said satellite is within said first range of elevation angles or said second range of elevation angles; and storing antenna data in a computer-readable memory device for use by said radio receiver to adjust said antenna, said antenna data relating one of said first and second antenna array patterns to each of said selected geographic areas depending on whether the elevation angle thereof is within one of said first range of elevation angles or said second range of elevation angles.
