Classification: CPC H | IPC H

Claim 6:
7. A satellite pointing method of an automatic satellite tracking antenna using auxiliary LNBs, the satellite pointing method comprising:
an origin checking operation of determining, by a controller, a current location of an antenna to check an origin;
a satellite signal receiving operation of receiving, by the controller, a satellite signal by controlling operations of two or more auxiliary feeders configured to be coupled to the antenna;
a control operation of tracking, by the controller, a target satellite by analyzing strength of the satellite signal received in the satellite signal receiving operation and generating a control signal for controlling a pointing direction of the antenna based on the tracked target satellite information; and
a satellite pointing operation of moving, by the controller, a location of the antenna according to the control signal generated in the control operation,
wherein
the satellite signal receiving operation further includes a simultaneous receiving operation of simultaneously receiving satellite signals from the two or more auxiliary feeders, and
the control operation further includes a simultaneous control operation of analyzing current location information of a target satellite collectively using the satellite signals simultaneously received in the simultaneous receiving operation, calculating a satellite orientation direction of the antenna according to the analyzed current location information to first generate a control signal,
calculating each of the satellite orientation directions using each of the satellite signals simultaneously received from the two or more auxiliary feeders, comparing the satellite orientation direction information based on one auxiliary feeder and the satellite orientation direction information based on the other auxiliary feeder to correct the first generated control signal to generate a final control signal for additionally controlling a pointing direction of the antenna.
