北斗系统在高速铁路控制网中的应用与精度分析

Application and Accuracy Analysis of Beidou System in High-speed Railway Control Network

目前北斗三号卫星组网运行,北斗系统各项应用也在不断推进与开展。然而北斗系统在高速铁路控制网中的应用较少,本文提出利用北斗观测数据进行某高速铁路工程控制网建立的设想,通过某高速铁路控制网观测数据进行相关实验与结果分析。通过TBC基线解算软件解算数据,并以GPS解算结果为参考,检验北斗系统(BDS)解算数据的精度,验证了基于北斗系统的高速铁路工程控制网建立的有效性与可行性。

In view of the current network operation of Beidou-3 satellites,various applications of Beidou system are also continuously promoted and carried out.However,the application of Beidou system in high-speed railway control network is less.This paper puts forward the idea of using Beidou observation data to establish a high-speed railway engineering control network,and carries out relevant experiments and result analysis through the observation data of an high-speed railway control network.Through the TBC baseline solution software to solve the data,and taking the GPS solution results as a reference,the accuracy of the Beidou System(BDS)solution data is tested,and the effectiveness and feasibility of the establishment of high-speed railway engineering control network based on Beidou system are verified.
