Satellite antenna and antenna frame controller

The utility model relates to a satellite antenna and an antenna frame controller. In the satellite antenna, a feed source is fixed at the position of a focus point of a parabolic reflecting face. Horizontal, pitching and position angle directions which are perpendicular to each other are arranged. Angle speed of a three-shaft frame in the horizontal, the pitching and the position directions and a deflection angle in the horizontal and the pitching directions of the three-shaft frame are detected by a sensor connected with the antenna frame controller. The antenna frame controller can calculate the antenna counter motion information of the three directions which are not affected by motion of a carrier according to the motion information. The counter motion information are sent to corresponding drivers respectively to drive corresponding motors to drive the three-shaft frame to move according to corresponding counter motion information respectively so as to offset directional variable quantity of the reflecting face caused by motion of the carrier. The satellite antenna and an antenna frame controller can timely complement angle variable quantity of the directing of the reflecting face in the angle directions of the position angle, the pitching angle and the horizontal angle to avoid polarization mismatch.
