A satellite system distributed simulation design and synchronous control

Based on the RTPS protocol and the NDDS network messaging middleware, a distributed real-time simulation network of satellite system is developed with Constellation software. Considering the structure feature of actual satellite, the module decomposition technique of distributed simulation is discussed in this paper. And with the RTPS protocol and NDDS network middleware, a synchronous control of the simulation network is designed and practiced to coordinate the simulation process. Finally, in order to test the distributed simulation performance, two kinds of satellite attitude control procession are simulated with real-time distributed simulation network. Compared with the results of Matlab integrated simulation, it shows that the distributed simulation network is a good platform for satellite design and the synchronous control method is effective..
