摘要： 随着GNSS应用的不断发展，实时位置服务已经成为国内外研究热点，而北斗卫星导航系统的实时服务尚处于发展阶段。本文基于卫星精密定轨基本原理，讨论了北斗导航卫星实时轨道确定策略；研究了基于北斗卫星质心和天线相位中心的SSR轨道改正值生成方法，并给出了一种适合北斗导航卫星的IODE值表达方式；基于国家基准站和全球MGEX站数据，进行了北斗导航卫星的实时轨道解算测试，结果表明，GEO卫星1D RMS精度优于400 cm，平均精度为223 cm，其径向精度优于20 cm；IGSO卫星精度优于30 cm，平均精度为22 cm，其径向精度优于10 cm；MEO卫星精度优于30 cm，平均精度为15 cm，其径向精度优于10 cm。

Abstract: With the continuous development of GNSS applications,real-time location service has become a hot research at home and abroad,but the real-time service of BeiDou navigation satellite system is still at the stage of development.Firstly,based on the basic principle of satellites precision orbit determination,this paper discusses the real-time orbit determination strategy of BeiDou navigation satellite.Secondly,the method of generating SSR orbit correction based on satellite center of mass and antenna phase is studied,and a way to express the IODE value for BeiDou navigation satellite is proposed.Finally,the data from the national and MGEX stations are processed to determine BDS satellite real-time orbit. The results show that,1D RMS accuracy of GEO satellite is better than 400 cm,the average accuracy is 223 cm,the radial accuracy is better than 20 cm;IGSO satellite accuracy is better than 30 cm,the average accuracy is 22 cm,the radial accuracy is better than 10 cm;MEO satellite accuracy is better than 30 cm,the average accuracy is 15 cm,the radial accuracy is better than 10 cm.

Key words: real-time orbit determination, SSR orbit correction, antenna phase center correction, IODE
