Zusammenfassung: | The invention discloses a mobile satellite television receiving system using an offset antenna and belongs to the technical field of satellite broadcast reception. The system solves the problems of low receiving efficiency and control precision, large power consumption and size and high cost of existing mobile satellite television receiving systems using reflector antennas. The mobile satellite television receiving system comprises the offset antenna and a servo system, wherein the offset antenna is mounted on the servo system horizontally and laterally. The middle of a front arm of a feed source rod of the offset antenna is connected with a pitching drive mechanism, and the other side of a reflecting surface of the offset antenna is connected on an antenna support, so that the offset antenna can rotate around a rotating shaft which penetrates through and is perpendicular to the middle of the front arm of the feed source rod, and torque of pitching rotation and diameter of a pitching movement locus circle of |
