摘要
北斗三号全球卫星导航系统自2020年7月31日正式开通以来,在铁路工程测量等领域的应用逐渐展开。本文以某普速铁路控制网建网为例,利用Trimble Business Cente(r TBC)、CHC Geomatics Office 2(CGO)和Hi-Target Business Center(HBC)三种商业软件对北斗卫星观测数据进行基线解算,并结合CosaGPS软件进行网平差处理。通过对比分析北斗系统与其他卫星导航系统(GPS、GLONASS、GALILEO)的基线解算精度,探讨北斗系统在铁路工程测量中的应用潜力。结果表明,北斗系统的定位精度与GPS相近,能够满足铁路工程测量的精度要求,且优于GLONASS和GALILEO系统。同时,多系统联合解算能够进一步提高测量精度,为铁路工程测量提供更可靠的数据支持。
Since the official launch of the Beidou-3 Global Navigation Satellite System on July 31,2020,its application in fields such as railway engineering surveying has gradually expanded.Taking the construction of the control network for a Conventional Railway as an example,this paper uses three commercial software,Trimble Business Center(TBC),CHC Geomatics Office 2(CGO),and Hi-Target Business Center(HBC),to process the baseline solutions of Beidou satellite observation data,and combines CosaGPS software for network adjustment processing.By comparing and analyzing the baseline solution accuracy of the Beidou system with other satellite navigation systems(GPS,GLONASS,and GALILEO),the application potential of the Beidou system in railway engineering surveying is explored.The results show that the positioning accuracy of the Beidou system is similar to that of GPS,which can meet the accuracy requirements of railway engineering surveying,and it is superior to the GLONASS and GALILEO systems.At the same time,the joint solution of multiple systems can further improve the measurement accuracy,providing more reliable data support for railway engineering surveying.
