提出了基于高速局域网的组合导航/制导仿真技术的原理和开展研究的四个环节,即理论研究、计算机仿真、半物理仿真和实物仿真。建立了基于高速局域网的组合导航/制导仿真平台框架,开发了计算机仿真平台、半物理离线仿真平台、半物理在线仿真平台和实物仿真平台,解决了客户机/服务器间的实时数据传输问题。以惯导/双星/GPS组合导航系统为例详细介绍了四种仿真平台的工作过程,并进行了半物理离线仿真试验,验证了仿真平台的实时性。

A principle and four key links of simulation technology based on Local Area Network （LAN） in integrated navigation/guidance were proposed, including theory study, computer simulation, semi-physical simulation, and physical simulation. The simulation platform framework based on LAN in integrated navigation^guidance_was proposed._Such four simulation platforms as computer simulation platform, semi-physical off-line simulation platform, semi-physical on-line simulation platform, and physical simulation platform were developed. And the problem of real-time data transmission between server and client machine was solved. The four simulation platforms were applied to the Initial Navigation System/Double-star System/Global Positioning System （INS/DS/GPS）, and the semi-physical off-line simulation experiment was carried out to verify the simulation platform＇s performance in real time.
