摘要
本文根据相对论基本原理，系统地阐述了GPS中必须仔细考虑的几项主要的相对论效应，包括运动时钟的时间膨胀、引力频移以及地球自转引起的Sagnac效应等，并对相对论效应在GPS中的实际应用进行了定量分析和讨论。
Relativity effects are the important part of error resources in GPS precise navigatiofi and tim-ing. According to the fundamental principles of relativity, this article describes several main relativity ef-fects that must be carefully account for in GPS first, including the time dilation of moving clocks, gravita-tional frequency shift, and the sagnac effect due to the earth's spin, And then, the article has made analy-sis in quantity and provided discussion to the application of relativity effects in GPS.
