Abstract
A system and method for automatically positioning/directing satellite antennas towards a satellite with which it is to communicate. The system and method may use characteristics of symmetry of mutually exclusive orthogonal axes. By using the symmetry of the antenna main beams, the ideal direction of the antenna can be attained and, at the same time, maximum cross-polarization may be achieved. The cross polarization may be required in order not to interfere with the orthogonal polarization. The system and method may position the Antenna on three mutually exclusive orthogonal planes, including the azimuth plane, the elevation plane, and the polarization plane. The system and method may include an indoor unit, which may include a satellite receiver, a telemetric transmission, and supply of voltage to a control system and which may control a drive motor and/or an electronic search device; and an outdoor unit, which may include a supervisory unit, a motor, and a control unit. The outdoor unit is preferably configured to conduct a search in the three orthogonal planes which may facilitate positioning the Antenna with a high degree of accuracy.
