HLA Application For Simulation System Of Deep Space Exploration

The deep space exploration is high investment, risky scientific and technological activities, simulation is one of the effective means to reduce the risk and production cost. For the autonomous spacecraft is very complicated, carrying overall mathematical simulation to such a system is very difficult to realize by one computer only. According to the system's own characteristics, we can adopt HLA (High Level Architecture) structure, distributing the simulation task to the nodal computer of each network.The main idea of HLA is to develop a common mainframe of modeling and simulation, which was the first goal of Department of Defense of USA's M&S Master Plan that published in 1995. It designed to facilitate the interoperability of simulation application and reusability of simulation resource. The object model of the autonomous spacecraft that the thesis discusses is an important part of HLA.Aim at deep space exploration simulation demand, research HLA key technology deeply, realize distributed deep space exploration simulation system, and resolve some key technology, such as:Apply Object-Oriented programmer method to design HLA federates frame code. So as to simulation object model depart from RTI simulation support, quicken design efficiency.In order to accomplish project"deep space exploration simulation system", designed HLA federate frame. Include function model design of three federate.The paper aim at the problem, combine application instance, object model of discuss deep space exploration simulation system. Discuss development procedure and run procedure of the deep space exploration simulation system.
