Study on simulation technology of integrated navigation/guidance based on high-speed LAN

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.
