Abstract： With the continuous maturity of satellite manufacturing and launching technology and the rapid increase in the number of satellites in China, the traditional single satellite measurement and control system has gradually been unable to meet the current domestic demand. To solve the problem of resource shortage of measurement and control system, this paper presents a design scheme of multi-satellite measurement and control system,。On the basic of satisfying the tasks of traditional measurement and control system, the scheme also improves the utilization rate of measurement and control resources.The scheme uses CPU as the main controller,and realizes the protocol processing of multi-satellite measurement and control data, at the same time, the secure transmission of measurement and control data is completed through measurement, control and scheduling FPGA. According to the design scheme, the hardware platform of multi-satellite measurement and control system is built, and the system test is carried out. By testing the hardware platform of multi-satellite measurement and control system, the security and reliability of the multi-satellite measurement and control system is verified.
