| Abstract: | 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. |
