Abstract:For formation small satellite communication requirements, the distributed formation small satellites communication system simulation platform based on Petri net had been put forward. First of all, the formation small satellite communication systems modeling TTDPN (T-Timed Discrete Petri Net) was established. The map between the model and distributed simulation platform was established too. According to the mapping relationship, the logic structure and data flow of formation small satellite communication simulation platform were designed. The distributed formation of small satellite communication system simulation platform was built up. Union space environment, attitude and orbital sub-system, the key technologies of Channel codec module and Spread Spectrum module in the Satellite communication system were verified by simulation. The simulation results show: the distributed formation small satellites communication system simulation platform based on Petri net can significantly reduce the simulation time, improve simulation accuracy and the simulation result confidence, and improve the communication system module design efficiency.
