PURPOSE: An active antenna system is provided to direct an antenna to a satellite direction by adjusting an antenna direction according to a vehicle location detected by a navigation system. CONSTITUTION: A satellite antenna(10) receives a signal from a satellite, and an antenna driving part(40) changes a direction of the satellite antenna according to an input control signal. A satellite tracking control part(60) receives vehicle location data from a navigation system(100) which searches travel direction and distance of a vehicle to display a vehicle location. The satellite tracking control part controls an antenna driving part so that the satellite antenna is directed to a satellite direction.
