Multi-aircraft measurement and control systems and signal synchronization technology is the basis of control. The unified carrier measurement and control system and single-station multi-satellite monitoring and control system are compared; the carrier signal synchronization technology and pseudo-code synchronization technology are analyzed. The discussion shows that the single-station multi-satellite monitoring and control system overcomes the problems of low accuracy, poor anti-interference ability and difficulty in multi-objective measurement and control of the unified carrier measurement and control system; Costas loop is the best device for suppressing carrier signals; digital matched filter ) Is the forefront of signal synchronization technology. Relevant researchers should continue to strengthen the signal synchronization design and implementation and bring about great development for the multi-aircraft measurement and control technology.
