This article describes a ground-based test equipment that is used to test the interface functionality of the satellite payload information processor and the design of the ground-based test equipment. Specific design includes the hardware and interface design of ground testing equipment, PCI card driver design, FPGA design, and supporting software design. The ground detection equipment can simulate the information processing box 6 peripherals for the information processing box communication RS422 interface, OC and reset command interface, AD acquisition interface, two-dimensional directional mirror interface for testing to ensure that the information processing box control functions as The load is actually in orbit to provide a reliable guarantee. The ground detection equipment developed from the traditional manual complex tests, easy to test the information processing box for ground testing and timely detection of problems for the satellite information processing box can be a good practical implementation of the mission is of great significance.
