一种基于HLA的卫星分布式仿真系统研究及其应用

RESEARCH ON AN HLA-BASED SATELLITE DISTRIBUTED SIMULATION SYSTEM AND ITS APPLICATION

卫星系统的仿真是一个多因素、多学科、多节点的复合性问题,传统的仿真方法存在扩展性和重用性差等缺点。基于HLA体系规范,构建一个良好扩展性和重用性的仿真系统能够对卫星总体设计方案进行仿真演示和验证,进一步提高卫星总体设计方案的科学化水平。基于HLA的卫星分布式仿真系统的优点在于不需对仿真系统主题框架做任何更改的情况下,通过XML配置文件实现不同任务目标的卫星任务仿真系统,从而实现仿真组建的发展和重用,解决单机系统仿真大规模扩展困难和难以真实描述系统间数据交互的难题。

Satellite system simulation is a complex problem with muhi-factor, multi-disciplinary and multi-node. Traditional simulation methods have the drawbacks in poor sealability and reusability. To build a good sealable and reusable simulation system based on HLA architecture specification can simulate, demonstrate and validate overall satellite design scheme and further improve the scientific level of design scheme. The advantage of the HLA-based satellite distributed simulation system presented in the paper is that without making any change on the theme framework of simulation system, it can realise simulation system for satellite missions with different mission objectives through XML configuration files so as to implement the development and reuse of simulation construction and to solve the puzzles of stand- alone simulation system in difficult to massively expand and to truly describe the data interaction between federates.
