Claim 0:
1. 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 receives a satellite signal from one selected auxiliary feeder, analyzes current location information using the received satellite signal, and calculates a satellite orientation direction of the antenna unit according to the analyzed current location information to first generate a control signal,
the controller receives a satellite signal from another selected auxiliary feeder, analyzes current location information using the received satellite signal, calculates a satellite orientation direction of the antenna unit according to the analyzed current location information, and
compares the satellite orientation direction information based on the one auxiliary feeder and the satellite orientation direction information based on the other auxiliary feeder to correct the first generated control signal based on the one auxiliary feeder to generate a final control signal.
