| 摘 要： | 相对论效应是影响GNSS导航定位精度的重要因素之一,本文对狭义相对论和广义相对论效应的原理进行了描述,推导并给出了4种不同的相对论效应计算方法,最后通过算例得出在卫星导航或单点定位中,基于2种不同星历的相对论效应计算结果相差不大,即使利用导航电文的信息,也可以有效消除相对论效应对导航定位的影响。

| Abstract: | The effect of Relativity is one of the important factors that have a significant on the accuracy of GNSS Precise Point Positioning and navigation.In this paper,principles of special relativity and general relativity were described,then,four methods were introduced to calculate equivalent distance correction.At last,from experiment it concluded that in satellite navigation or Precise Point Positioning,the result of effect of relativity calculated by broadcast ephemeris and precise ephemeris could be identical in general. |
