Abstract
A system for causing an antenna controller for a satellite antenna to determine the alignment position of the antenna for a given satellite, whereby antenna installation time may be substantially reduced when the alignment position of the antenna for a large number of satellites must be determined. The system includes means for measuring the alignment position of the antenna for at least two reference satellites; and means for processing said measurements with stored data indicating the relative positions of the reference satellites and other satellites in accordance with an algorithm to determine the alignment positions of the antenna for the other satellites. The system also includes means for causing an antenna controller for a satellite antenna to determine the skews of the linear polarization axis of the antenna for respectively matching the linear polarization axis of odd-numbered and even-numbered channels received from a satellite. One embodiment of the system also includes a portable device into which data indicating the relative positions of the reference satellites and the other satellites and/or data indicating relative skews for matching the linear polarization axis of…
