| 摘 要： | 简述了四大主流全球卫星导航系统常用时间系统，通过UTC（协调世界时）中间量来实现各个系统相互之间时间转换。通过实例重点比较了北斗、GPS和格洛纳斯通用RINEX导航文件时间系统的差异，只有通过时间转换构建统一的时间基准，在进行高精度GNSS数据处理时才能下载到相对应的各种精密文件，提高解算精度。

| Abstract: | In this paper,the common time systems of the four major global satellite navigation systems are briefly described.The time conversion between each system is realized by UTC intermediate.This paper focuses on the comparison of the differences among Beidou,GPS and GLONASS general RINEX navigation file time systems through examples.Only by constructing a unified time benchmark through time conversion,can the corresponding precision files be downloaded during high-precision GNSS data processing to improve the calculation accuracy. |
