With the development of China’s aerospace industry, the number of in orbit spacecraft has been increasing year by year, working mode has been transmitted from manual operation to automated operation for land measurement and control station. It needs to turn on or turn off by manual work for HF receiver of Ship-borne TT C S-band radar in daily work. Also it needs to identify and set signal frequency point locally in tracking spacecraft which resulted in the shortcoming of timeliness and work efficiency low. In order to solve the problem, a design is given by this paper about a remote device for powering on/off and polarization judgment of flight targets, as well as an automatic frequency identification system. The system is non-invade. It can switch flexibly between normalized tasks and maritime measurement and control and does not affect the original working mode of the system. It is developed based on LabWindows/CVI platform, which realize the function of remote electric, acquire and set signal frequency point automatically by controlling network relay and spectrum analyzer. The result shows that the system improves the timeliness and reliability of Ship-borne TT C station in daily work.
