摘    要:从GNSS技术在铁路列车定位中的应用优势出发,分析基于卫星导航系统的列车定位原理与需求,围绕GPS,GLONASS,GALILEO和北斗四大全球导航卫星系统,介绍国内外利用卫星导航实现铁路列车位置服务的应用情况,在专用型导航接收机设计、多传感器数据融合、轨道电子地图生成与辅助、完好性与安全性保障等4个方面总结了基于卫星导航的列车定位在核心理论方法层面的主要进展,并对其未来发展趋势进行展望。

Abstract: Starting with the application advantages of global navigation satellite system technology in railway train positioning, principles and requirements of the satellite navigation system based train positioning were analyzed. Based on the current satellite navigation systems including GPS, GLONASS, GALILEO and BeiDou Navigation Satellite System, application of satellite navigation based train positioning technology at home and abroad was roundly introduced. From the aspects of specific satellite navigation receiver design, multi-sensor information fusion, track map generation and assistance, and assurance of integrity and safety, main research progress of this field was summarized at the theoretical-methodological level. Finally, prospects of the future development were presented correspondingly.
