Abstract

본 발명은 위성방송 안테나의 추적제어 방법 및 장치에 관한 것으로서, 이는 다중의 위성으로부터 송출되는 위성방송 전파의 수신감도를 자동으로 추적하여 수신감도가 최적인 상태가 되도록 위성 안테나를 자유자재로 원격조정하도록 한 것이다. 이와 같은 본 발명은 파라볼라 안테나 및 위성방송 튜너를 통해 선국되어 얻어진 위성방송 수신전파의 감도를 측정하는 단계와; 상기 측정한 수신전파 감도의 세기와 설정값과를 비교 판단하는 단계와; 상기 판단한 결과 수신전파 감도의 세기가 낮으면 파라볼라 안테나를 단계적으로 상하, 좌우 회동시켜 수신전파의 감도가 최고치가 되도록 반복적이고 주기적으로 조절하는 단계로 이루어짐을 특징으로 한다.The present invention relates to a tracking control method and apparatus for a satellite broadcast antenna, which automatically tracks the reception sensitivity of satellite broadcast waves transmitted from multiple satellites and freely remotely adjusts the satellite antenna so that reception sensitivity becomes optimal. . The method includes measuring a sensitivity of a satellite broadcast receiving radio wave selected through a parabolic antenna and a satellite broadcast tuner; Comparing and comparing the measured intensity of the received radio wave sensitivity with the set value; When the intensity of the received radio wave is low as a result of the determination, the parabolic antenna is turned up and down, left and right, and repeatedly and periodically adjusted so that the sensitivity of the received radio wave is maximized.
