摘　　要：利用GPS广播星历计算卫星坐标是GPS实时定位中的重要部分,卫星轨道精度对GPS定位结果有很大影响。依据Bernese卫星定轨流程,利用Fortran语言实现了卫星轨道处理程序,并通过实例对计算得到的卫星轨道坐标与Bernese5.0软件处理的广播星历和精密星历得到结果进行比较分析,误差均小于±2.5m,程序定位效果良好,证实了自编程序的可行性。Using GPS broadcast ephemeris calculation satellite coordinates is the most important part of GPS real-time positioning. Accuracy of satellite orbit has a great influence on GPS positioning res-ults. In this paper, based on the Bernese satellite orbit determination process, satellite orbit processing program was achieved by using Fortran language, and compared the results of using satellite orbit pro-cessing program and using Bernese5.0 software to process broadcast ephemeris and precise ephemeris, the errors are less than ± 2.5 m. By this program positioning satellite-position is good, and confirmed the self-programming is feasible.
