Abstract

The invention discloses an automatic tracking system for a satellite signal, and the system comprises an automatic tracking unit, a wave control unit and a stepping tracking module. The automatic tracking unit comprises an FPGA controller and a signal processing unit. The bidirectional port of the FPGA controller is connected with a signal processing unit through a control line, and the input endof the FPGA controller receives an analog signal of an analog-to-digital converter. The input end of the analog-to-digital converter is connected with a receiving array through a radio frequency channel, the bidirectional port of the receiving array is connected with a transmitting array, and the output end of the transmitting array is connected with the signal processing unit through the wave control unit. The system combines a program tracking method and a stepping tracking method, and can obtain a satellite maximum value. The FPGA controller is used for adjusting the azimuth angle and pitchangle of an antenna platform, and carrying out the corresponding angle compensation, thereby enabling the satellite antenna to remain aligned with a satellite, and improving the tracking performanceof the satellite, and enabling the practicality to be high.

Description

technical field [0001] The invention relates to the technical field of automatic tracking systems, in particular to an automatic tracking system for satellite signals. Background technique [0002] The application fields of satellites are very extensive. According to their different functions, they can be divided into many types. Since humans entered space, the functions and applications of satellites have flooded our lives. Satellite TV is one of the satellite applications. Satellite TV broadcasting is realized by the synchronous satellite forwarding function. The ground port transmits relevant audio and video signals to the synchronous satellite, and the synchronous satellite transmits the audio and video signal in a certain direction. The area covered by the signal can be used Receive the device to receive the signal and watch the program: [0003] (1) The most important key issues of the vehicle-mounted TV system are to maintain the stability of the antenna platform and...
