| 摘 要： | 以北斗卫星测码伪距和Wi—Fi信号强度反算出的距离作为基本观测值，组成联合观测方程，实现北斗和Wi—Fi节点的联合定位。通过实测数据实验分析结果表明，在相互通视的环境中，北斗和Wi～Fi节点各自不能独立定位的情况下，两者联合定位的偏差小于15m（80％的可信度）。北斗和Wi—Fi节点联合定位是一种实用的定位方式。

| Abstract: | Using the Beidou pseudorange measurement and the distance derived from Wi Fi signal strength as the basic observations,it can construct the observation equation and realizes combined Beidou and Wi-Fi positioning. The analysis of experimental results shows that the accuracy of combined positioning is less than 15 m（80% confidenc elevel）in line-of-sight circumstances when Beidou and Wi-Fi cannot be used for positioning independently. Combined Beidou and Wi-Fi is a practical way of positioning. |
