摘要
文章以铁路维护部门对车辆定位管理所提出要求为核心,结合北斗导航发展现状,围绕相位差分定位展开了讨论。首先介绍了该系统的构成、运行原理、误差源和现有技术;其次结合实际情况对定位模型进行了建立;最后利用动态跑车试验,多角度验证了相位差分定位对保障铁路作业安全的价值。供相关人员参考。
This article focuses on the requirements of the railway maintenance department for vehicle positioning management,combined with the development status of Beidou navigation,and discusses phase differential positioning.Firstly,the composition,operating principle,error source and existing technology of the system are introduced;secondly,the positioning model is established based on the actual situation;finally,the dynamic sports car test is used to verify the value of phase differential positioning to ensure the safety of railway operations from multiple angles.For reference of related personnel.
