Classification: CPC H | IPC H

Claim 1:
2. A satellite pointing system of an automatic satellite tracking antenna using auxiliary LNBs, the satellite pointing system comprising:
an antenna unit configured by coupling a main feeder receiving a satellite broadcast signal and two or more auxiliary feeders to an antenna; and
a controller tracking a location of a target satellite by analyzing strength of each satellite signal received through the auxiliary feeders and generating a control signal for controlling a pointing direction of the antenna unit based on location information of the tracked target satellite,
wherein
the controller simultaneously receives satellite signals from the two or more auxiliary feeders, analyzes current location information using the received satellite signals, and calculates a satellite orientation direction of the antenna unit according to the analyzed current location information to first generate a control signal,
calculates each of satellite orientation directions using each of satellite signals simultaneously received from the two or more auxiliary feeders, and compares satellite orientation direction information based on one auxiliary feeder and satellite orientation direction information based on the other auxiliary feeder to correct the first generated control signal to generate a final control signal for controlling a pointing direction of the antenna unit.
