Abstract
Provided is an antenna system for tracking a satellite which includes a fixed body and a rotating body. The antenna system includes a transmitting/receiving unit having a transmitting channel and a receiving channel for signal power, a driving unit for enabling mechanical motion of the rotating body for satellite tracking, and a control unit for monitoring and controlling the operation of the driving unit. Accordingly, the various kinds of the components of the antenna system mounted and operated on the movable body can be minimized and the output of the transmitted signal required in the antenna system can be simply replaced, thereby simplifying the configuration of the system and reducing the production cost of the system. In addition, the STR having the tracking signal processing function in the digital mode as well as the general analog mode is mounted on the antenna system, thereby improving accuracy of satellite tracking. Moreover, the posture of the antenna system can be stably maintained regardless of the motion of the movable body in the moving environment by using the driving unit and the control unit which are designed for stably controlling the elevation, azimuth and antenna rotating angle, thereby improving communication performance that is the intrinsic object of the antenna system.
