基于北斗导航的列车定位技术研究

北斗卫星已逐步具备应用于列车定位的能力,为北斗卫星导航在铁路系统中的应用发展提供重要契机。将北斗卫星导航系统应用到列车定位系统,不仅能提高定位精度,而且能降低成本,也是列车运行控制系统安全性与可靠性的有力保障,对于列车定位系统的研究具有深远意义。与四大卫星导航系统进行比较,根据列车定位技术的分类,归纳各自特点和研究方向,最后指出基于北斗导航的列车定位技术下一步的重点工作。

Research on Train Positioning Technology Based on Bei Dou Navigation System

BeiDou navigation satellites are getting ready to support train positioning, which provides an important opportunity for the application of BeiDou Navigation Satellite System(BDS) in railway systems. BDS can not only improve train positioning accuracy but also reduce costs, ensuring the safety and reliability of the train operation control system. Therefore, BDS is of great significance to the research on train positioning systems. The paper compares four major satellite navigation systems, summarizes their features and points out the direction of further research according to the classification of the train positioning technology. In conclusion, it describes the key points of the next stage of research on BDS train positioning.
