HLA中时间管理策略在GPS导航系统仿真中的应用

Application of Time Management Strateg of HLA in GPS Simulation

高层仿真体系结构(HLA)作为新一代分布式仿真体系结构,在军用以及民用计算机仿真中得到越来越广泛的应用,而HLA中最为复杂的应用为数据分发和时间管理模块.本文从HLA的基本思想出发,分析了HLA中的时间管理策略,最后灵活地应用HLA的时间管理策略实现了全球定位系统(GPS)应用中通信模型的协调和统一,避免了容易出现的因果和逻辑颠倒错误,实现了GPS导航信号、信道和接收机三者之间的并行处理,提高了系统的运行效率.

HLA is widely used in both military and civil computer simulation as a new-generation simulation architecture. The most complex parts of HLA are data distribution and time management. In this paper, the time management strategy is analysed and communication in GPS application is realized, avoiding the error of consequence.
