摘要
随着北斗卫星系统(BeiDou Navigation Satellite System, BDS)组网成功,BDS系统在各领域方面的应用随之增加,但是缺少在城市地铁首级控制网中的应用。本文以某城市地铁首级控制网实测数据为例,研究了基于BDS卫星系统的控制网解算与结果精度分析。以成熟的商用软件TBC解算数据,并以全球定位系统(Global Positioning System, GPS)解算数据作为参考,验证了BDS系统解算精度与GPS系统解算精度处于同一水平。充分证明了BDS系统在城市地铁控制网建立的有效性与适用性。
With the successful networking of beidou-3 satellite,the application of Beidou system in various fields increases,but it is lack of application in the primary control network of urban subway.Taking the measured data of the primary control network of a city subway as an example,this paper studies the control network solution and result accuracy analysis based on Beidou satellite system.Taking the mature commercial software TBC solution data and GPS solution data as a reference,it is verified that the accuracy of Beidou system is at the same level as that of GPS system.It fully proves the effectiveness and applicability of Beidou system in the establishment of urban subway control network.
