摘　　要：随着蜂窝移动通信技术的迅速发展,蜂窝无线定位技术越来越受到人们的重视。在分析应用于无线蜂窝网络的TOA和TDOA时间定位方法的基础上,对基于时间的非线性最小二乘(NL-LS)算法、Chan算法、泰勒级数法等定位算法进行了探讨和比较,最后分析了定位误差产生原因以及减小定位误差的办法。With the rapid development of cellular mobile communication technology, wireless location techniques attract more and more attention, This article firstly introduces the location technology of time - based system in cellular networks, then analyses time- based location algorithms, such as NL -LS algorithm, Chan algorithm, Taloy series algorithm and the others. Analysis of the errors of location and methods of mitigating the errors is presented.

关 键 词：无线定位 TOA/TDOA 定位误差 蜂窝网
