A satellite tracking antenna system with improved tracking characteristics and operating method thereof are disclosed. The system independently controls an elevation angle and an azimuth angle of an antenna according to the movement of a vehicle, controls the elevation angle of the antenna only when a satellite elevation-angle variation is equal to or higher than a reference value, so that it can improve the tracking speed and performance of the satellite. The system includes an antenna unit, a GPS receiver, an azimuth-angle gyro-sensor, a control board, a motor unit. The control board includes an elevation-angle controller and a main controller. The motor unit includes an elevation-angle motor and an azimuth-angle motor. |
