SATELLITE ANTENNA ALIGNMENT SYSTEM ABSTRACT OF THE DISCLOSURE 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 relative 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 given satellite and the reference satellites in accordance with an algorithm to determine the alignment position of the antenna for the given satellite. 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 the given satellite. One embodiment of the system also includes a portable device into which data Indicating the relative positions of the given satellite and the reference satellites and/or data indicating relative skews for matching the linear polarization axis of odd-numbered and even-numbered channels received by a reference antenna from the given satellite may be downloaded from the antenna controller for the reference antenna and from which the downloaded data may be uploaded into the first said antenna controller for said storage therein.
