Provided are a satellite tracking system and a method thereof using a frequency scanning effect, by which satellite signals transmitted from a satellite via an antenna mounted on a moving body are analyzed using a frequency scanning effect to acqire a position of the satellite, and the acquired position of the satellite is continuously tracked, thereby smoothly receiving the satellites signals. The satellite tracking system includes an antenna unit including a first antenna having feed lines configured to have different lengths for transmitting satellite signals received from the satellite so that directions of an antenna beam vary according to the respective frequencies of satellite channels received from the satellite by a frequency scanning effect, a low noise block down converter (LNB) for receiving the satellite signals of the respective frequencies received through the antenna unit via feed lines and converting the received satellite signals into intermediate frequency (IF) satellite signals, a control board for detecting at least two different signals among the IF satellite signals converted by the LNB and measuring and comparing amplitudes of the signals to acquire a position of the satellite, a motor for rotating the antenna unit to be directed to the position of the satellite acquired by the control board, and a transmission means for supplying power to the respective elements and transmitting the IF satellite signals converted by the LNB to a TV monitor and a satellite broadcasting receiver. |
