In the process of developing a satellite attitude control subsystem,a lot of closed- loop simulation and test are needed. In order to meet a large number of needs which about the simulation and testing of attitude control. The satellite ground test system about attitude control dynamics simulation is designed. The system is a real-time closed-loop simulation system which based on network and fiber reflection memory. It is mainly consisted by dynamic supervision,real-time data acquisition simulation system,database and dynamic simulator. The system uses Simulink/XPC real-time simulation system as the basic framework. And the whole simulation system is built as a real-time and fast simulation system and it based on Simulink/XPC. The dynamic academic supervision is based on XPC satellite dynamics model, network and optical fiber reflection memory which in order to data display, storage and forwarding. Dynamics instruction run the model of satellite dynamics simulation,and it release sensor data and monitor data from executing agencies. In order to ensure the data which communicate between ground simulation test system and the satellite is not distortion. The data real time acquisition simulation system is mainly used for data communication between the satellite computer and the dynamic simulation model. This satellite ground test system about attitude control dynamics simulation has well application in several satellite engineering practice.
