Abstract
The present invention relates to a satellite tracking antenna system and a satellite tracking method. Step tracking in which the size of a satellite signal sampled in at least one position in which a reflector of the satellite tracking antenna system is tilted is compared to track a satellite is performed, and a measured value of the satellite signal sampled in a specific position in which the reflector is tilted in N-1th tracking and a measured value of the satellite signal sampled in the specific position in which the reflector is tilted in Nth tracking are averaged to compute a value. The reflector is driven according to the value to track the satellite, thereby minimizing a satellite tracking error caused by a sudden movement of a mobile body equipped with the satellite tracking antenna system.
