Hla In The Space Environment Elements Simulation

With the development of modern high technology, the field of war will bo extended to the space. As the important carrier of space object, the simulation nn space environment is the most effective and feasible way to explore and research iho space.Bui Iding the common technical framework of modeling and simulation is the key in share the resource and construct an integrative modeling and simulation environment. So High Level Architecture (HLA) is presented as a standard and advanced system framework.Combined with the project of "Space Environment Simulation Platform" , tho key technology and mechanism of HLA as well as the basic factors of space environment were analyzed. "Space Environment simulation platform" , which is designed based on HLA , is proved to work effectively. The main content in this thesis can be summarized as follows:1, The basic theory of HLA is introduced systematically.2, The base factors of space environment and their general physical patterns are illustrated in details.3, The application of HLA in "Space Environment simulation platform" is investigated, and "Space Environment simulation platform" simulation federation is built.?, Through constructing FOM/SOM , the way of how to build the federate of"the base factors of space environment" is explained in detail. 5, Explorations and experiments are made on the modeling and visualization of space environment. And the modeling and visualization of middle and upper atmosphere were realized as a pilot study.
