Modeling/simulation in satellite constellation of mobile communication system

Satellite mobile communication is one of the key means of modern communication. Using satellite constellation, the true globe mobile communication can come into being. Coverage performance both in time and space, communication chains, total cost and so on factors should be synthetically considered during the process of system design and construction. It is difficult to have an all-sided and visible analytical result of all these aspects simply using mathematical method. Thus, based on modern modeling/simulation technology, the satellite constellation communication simulation system was constructed using HLA/RTI and STK. The system can obtain and save model data and configure schemes in database conveniently using XML interface. The schemes can be reconfigured and simulated in real-time or faster-than-real-time to get comprehensive evaluation result. Vivid two-dimensional and three-dimensional scene, report and curve were also provided. It affords satellite constellation communication system a general simulation and testing platform, and also supports other satellite constellation system design in a certain extent.
