摘要： An antenna system and a corresponding method for satellite lock-on applied to vehicles automatically lock on at least one satellite in the space by means of a lock-on signal. The technique features on a scan driving signal that initiates a space scan of the antenna system so as to obtain a scan data. According to peak values of the scan data, coordinates of a plurality of satellites in the space are realized and individually recorded. Then, after receiving a lock-on signal, the satellite coordinate of the satellite to be locked is retrieved so as to drive the antenna to point at the satellite to be locked.

摘要： A method for satellite lock-on in an antenna system by channel selection is initiated by receiving a channel selection signal. The channel selection signal is flagged to retrieve satellite parameters corresponding to the selected channel from a pre-stored satellite channel table which provides a correlation among the channels, the bands and the satellite coordinates. Then, according to the retrieved satellite parameters, an antenna control signal and thus a drive signal are generated orderly to drive the antenna to direct at the satellite responsible to the selected channel.
