  • Patent number: 5214364
    Abstract: Apparatus and method for automatically controlling the rotation of an angularly positionable antenna from one angular position to a desired new angular position. The disclosed technique provides the user with a list of destination indicia, each of which corresponds to a geographic location. The user is also provided with a selector for choosing one or more of the available destination indicia. Once the user selects a destination index, a retrieval system automatically retrieves the appropriate geographic reference location from a destination indicia table stored in memory. A calculation is then automatically performed to determine the desired angular position of the antenna with respect to an arbitrary reference angle. The antenna rotor shaft is then energized to rotate the shaft to the desired angular position.
