面向北斗三号的铁路既有卫星导航应用适应性研究

Adaptability of existing railway satellite navigation applications for Beidou-3

摘要: 文章介绍了北斗卫星导航系统（简称：北斗）的概况和铁路既有卫星导航应用情况，分析了北斗三号全球卫星导航系统（简称：北斗三号）技术体制变化对铁路既有卫星导航应用的影响，研究了铁路既有卫星导航设备对北斗三号应用的适用性，提出了铁路既有卫星导航应用向北斗三号服务过渡的方案，为解决铁路既有卫星导航应用的过渡问题提供了思路。

Abstract: This paper introduced the general situation of BeiDou navigation satellite system (BD) and the applications of existing railway satellite navigation, analyzed the impact of changes in the technical system of BeiDou-3 global satellite navigation system (abbreviated as BD-3) on the application of existing railway satellite navigation, and studied the applicability of existing railway satellite navigation equipment to the application of BD-3, proposed a plan for the transition of existing railway satellite navigation applications to BD-3 service, which provided ideas for solving the transition problem of existing railway satellite navigation applications.
