Patent ID: 8120541

Claim:
An antenna system for tracking a satellite, which comprises a fixed body for transmitting and receiving communication and broadcasting signals to/from an external terminal system and receiving AC power from an external source, and a rotating body rotatably coupled to the fixed body in multi-axis directions for tracking a direction of the satellite, and transmitting and receiving signal power to/from the satellite through a free space, wherein the antenna system comprises: a transmitting/receiving unit having a transmitting channel and a receiving channel for signal power wherein the receiving channel includes an antenna; a driving unit for enabling mechanical motion of the rotating body for satellite tracking and comprising a plurality of motors for driving the antenna system in an azimuth direction and in an elevation direction, and rotating the antenna itself to compensate for a polarization error generated by a relative position of the antenna system to the satellite; and a control unit for monitoring and controlling the operation of the driving unit to orient the antenna system towards the satellite in real-time.
