GPS信号接收机作业的关键,在于如何识别和锁定来自不同GPS卫星的导航定位信号,并逐一测量它们到达接收天线的传播时间,进而算得GPS信号接收机至各颗被测GPS卫星的距离,这也是GNS S信号接收机的基本特性,本文对此进行了较深入的解析。

The operation key of GPS signal receivers lies in identifying and locking the navigation/positioning signals from different GPS satellites,and measuring one by one that they reach the propagation time to the receiving antenna,then calculating the distances from the GPS signal receiver to GPS satellites;These are also the basic characteristics of GNSS signal receivers. On these this paper performs a more in-depth analysis.
