System and method for controlling satellite finding antenna

The invention provides a system and method for controlling a satellite finding antenna. The system comprises an antenna feeder subsystem for receiving a beacon signal of a target satellite, a satellite communication subsystem for converting the beacon signal to the beacon signal of L wave band, a servo control subsystem for determining the angle adjustment information of the antenna according to the current angle information of the position of the target satellite and the antenna during first alignment of the antenna and determining the angle adjustment information of the antenna according to the converted beacon signal when judging that the angle of the antenna is changed, and an antenna driving subsystem for driving the antenna to direct the target satellite according to the angle adjustment information. In the invention, the angle adjustment information of the antenna is determined according to the beacon signal of the target satellite during angle change after antenna alignment so as to drive the antenna to be aligned to the target satellite according to the angle adjustment information to realize the automatic satellitet of alignment program, ensure that the antenna is capable of being aligned to the satellite at any moment and improve the working efficiency.
