基于HLA的航天飞行任务联合仿真系统设计

简要说明了HLA的基本特点，描述了一个已经实现的航天测控仿真系统，并将其结构思想与HLA进行了对照。在此基础上，提出了一个依据HLA标准，对航天员座舱仿真、火箭和飞船仿真、测控网仿真等进行集成的航天飞行任务联合仿真系统框架，分析了各个仿真联邦成员的功能需求和信息接口，并着重介绍了针对任务要求的时间管理、数据通信等关键RTI机制的设计和实现方法，以及参照FEDEP模型和借助商业成品软件工具的系统开发策略。

Design of HLA-based United Simulation System for Space Flight Missions

This paper first of all introduces the basic features of HLA, and describes an implemented space flight TT&C simulation system by making a structural comparison with HLA. It then proposes a HLA-based simulation framework for the integration of astronaut cockpit, launch vehicle, spaceship and TT&C network simulation. It also analyzes the functional requirements and information interfaces of the federates, gives a highlighted introduction of the design and implementation of key RTI mechanisms such as time management and data communication that satisfy mission demands, and presents the system development policy based on the FEDEP model and commercial off-the-shelf (COTS) software tools.
