Research of multidisciplinary inter-satellite communication system simulation

Communication systems of formation micro-satellites involve a variety of algorithms and models. In this paper we establish the communication systems modeling TTDPN (T-Timed Discrete Petri Net) of formation small satellites, and establish the map between the model and multidisciplinary simulation platform. The multi-disciplinary system design method is presented based on inter-satellite communication simulation platform by using HLA. The attitude, space environment, and orbital sub-system, the channel codec module in the satellite communication system are verified by simulation studies. The simulation results indicate that the multidisciplinary communication system of formation small satellites based on Petri net can significantly reduce the simulation time, and improve the module design efficiency of the communication system.
