蜂窝移动电话定位系统的时间同步

The Time Synchronization of Cellular Mobile's Location System

介绍了蜂窝移动电话的定位方案和TDOA定位原理,分析了用于基站同步的GPS时间同步方法,提出了采用GPS共视法时间同步的方法,可提高蜂窝移动电话定位系统的定位精度。

This article has introduced the location way and TDOA'slocation principle of honeycomb cellular telephone, and has analyzed GPS that is used at the base station time synchronous method, and has put forward to use GPS common inspection method of time synchronization, and can raise the location precision of the system.
