This paper introduces a ground testing equipment for testing a satellite payload informationprocessing box interface functions and the related design work of the ground testing equipment. Thespecific design includes hardware and interface design of the ground testing equipment, PCI card driverdesign, FPGA functional design, as well as supporting the preparation of design software. The groundtesting equipment can simulate six peripheral devices of the information processing box for testing thecommunication RS422 interface, OC and reset command interface, AD acquisition interface, and two-dimensional pointing mirror interfaces of the information processing box, it can ensure that theinformation processing box controlling functions properly, and provide a reliable guarantee for the actualpayload in orbit. The development of the ground testing equipment escapes from the traditional andcomplex manual testing, and tests the information processing box on ground easily. So, it can identifyproblems in time, and have great significance for the satellite payload information processing boxexecuting the tasks in practical well.
