Patent ID: 7446721

Claim:
A satellite tracking antenna system comprising: a reflector directed to a predetermined satellite, tilted in a direction of a predetermined azimuth or elevation toward the satellite, and receiving a satellite signal from the satellite; an azimuth signal level measuring part computing a first azimuth measurement value which is a difference between azimuth satellite signal level values sampled respectively in a first azimuth position and second azimuth position of Nth tracking of the reflector, computing a second azimuth measurement value which is a difference between azimuth satellite signal level values sampled respectively in the first azimuth position and second azimuth position of N−1th tracking, and averaging the computed first azimuth measurement value and the second azimuth measurement value to generate an azimuth error signal; an azimuth position/speed control part generating an azimuth control command signal with respect to the satellite directional direction using the azimuth error signal; and a reflector driving means for driving the reflector in azimuth direction according to the azimuth control command signal.
