Satellite identification and tracking system is the key technology in the control system of Satcom on the Move(STOM).The scheme adopted by the current satellite identification and tracking system is studied.According to the actual working requirements of STOM system, a dual-source scheme for the satellite identification and tracking system is proposed.Based on the scheme, the hardware and software design of the dual-source satellite identification and tracking system is completed.The scheme can detect the changes of satellite signal intensity in real time with fast response speed and high tracking accuracy, so that the system can identify and track the satellite by detecting particular signals and the changes of signal intensity, and keep the communication link smooth.In the phase of detecting beacon identification satellite, an FFT algorithm of correcting frequency deviation is adopted, which improves the accuracy and stability of the system.
