摘要
分析了伪卫星导航定位系统的优点与定位原理,给出了该系统在物资管理中的具体应用方法、系统构造方案和组网实现方法。同时,分析了伪卫星系统室内组网时,影响定位精度的远近效应和多径效应,并给出了减小这些效应影响的优化方案。
The advantages and positioning principle of the pseudolites navigation and positioning system are analyzed in this paper. The specific application method of the system in materials management, the scheme of system structure and the implementation method of networking are provided. The near-far effect and multipath effect which affect the positional accuracy are analyzed. An optimization plan to reduce the impact is given.
