A system and method for acquiring a satellite with an antenna using a computing portion which determines the variation between the actual orientation of the antenna and an optimum orientation to acquire a satellite. The deviation is computed by: determining the actual orientation of the antenna with respect to true North and producing a first signal indicative thereof; determining the location of the antenna on the Earth and producing a second signal indicative thereof; determining the elevation of the satellite with respect to the location of the antenna and producing a third signal indicative thereof; determining the azimuth of the satellite with respect to the location of the antenna and producing a fourth signal indicative thereof; and using log data for the satellite along with the first, second, third, and fourth signals to compute the position of the satellite relative to the antenna and produce a signal indicative of the deviation. A display is used for illustrating the deviation and can be used as a coarse adjustment device. A second display provides information as to the received signal strength from the satellite to the antenna and can be used as a fine adjustment device. The coarse and the fine adjustment devices interact to provide an effective technique to acquire the satellite.
