摘要
介绍了GPS共视授时的基本原理,在此基础上分析了GPS共视授时中多径效应影响。多径效应是GPS接收机测量中遇到的主要误差之一,减小多径误差可以提高GPS共视授时的精度。该文分析了目前抗多径的方法,同时探究了GPS共视授时中怎样进行抗多径干扰,该结论对进行GPS共视授时研究有一定的参考价值。
Introduces the basic principle of GPS common-view time service, on the basis of the analysis of GPS common-view time service in the influence of multipath effect.The multipath effect is GPS receiver is measured in one of the major errors, re- duce the multipath error can improve the GPS common-view time service precision. This paper analyzes anti-multipath meth- ods, and explores GPS common-view time how anti multipath interference, the conclusion of the GPS common-view time ser- vice research has a certain reference value.
