| 摘 要： | 室内定位与室外GPS在误差源上有着明显的差别。文中针对某室内伪卫星定位系统精度达2cm的定位要求,在误差分析的基础上,提出三种伪卫星的布局。对其中两种布局进行HDOP仿真,并从布局的角度重点研究远近效应和多径效应,确定了在具体环境下伪卫星布局的最终方案。在此基础上进行发射天线的参数设计,为系统实现2cm的高精度定位打下基础。

| Abstract: | There are evident differences in the sources of error between the indoor positioning system and GPS.This paper discusses three different configurations of pseudolites to meet the requirement that the positioning accuracy of indoor positioning system using pseudolites should reach 2cm,and obtains the simulation results of HDOP of two different configurations among them.After the emphatic research on the near-far effect and multipath effect,the final plan of pseudolites' configuration in the concrete environment is fixed on. Based on the configuration,the method of the antenna design is put forward,which is the foundation of the realization of the 2cm positioning accuracy. |
