Claim 5:
6. 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 first receiving operation of receiving a satellite signal from one selected auxiliary feeder, and
after the first receiving operation is performed,
the control operation further includes a first control operation of analyzing current location information of the target satellite using the satellite signal received in the first receiving operation and calculating a satellite orientation direction of the antenna according to the analyzed current location information to first generate a control signal,
after performing the first receiving operation and the first control operation,
the satellite signal receiving operation further includes a second receiving operation of receiving a satellite signal from another selected auxiliary feeder, and
after the second receiving operation is performed,
the control operation further includes: a second control operation of analyzing current location information of the target satellite using the satellite signal received in the second receiving operation, calculating a satellite orientation direction of the antenna according to the analyzed current location information, comparing the calculated satellite orientation direction and the satellite orientation direction information based on the first control operation, and correcting the control signal based on the first control operation to generate a final control signal for controlling a pointing direction of the antenna.
