摘要: 为了研究北斗三号全球卫星导航系统(BDS-3)对建筑物的高精度、连续、实时变形监测,本文基于BDS-3与CORS网络,采用NTRIP协议实时传输监测数据,利用精密单点定位技术实时解算坐标,使用GAMIT/GLOBK静态差分解算,实现毫米级变形监测,并在此基础上开发了实时变形监测系统。试验结果显示,60 d基线解算的归一化均方根(NRMS)均值为0.191 7,重复性精度优于2 mm;坐标时间序列加权均方根(WRMS)约1 mm,静态解算达毫米级;动态解算精度为水平5 mm、垂直13 mm。本文验证了BDS-3可为城市建筑物监测提供解决方案,具有工程应用价值。

Abstract: In order to study the high-precision,continuous,and real-time monitoring of building deformation by BDS-3,this paper conducts research based on the BDS-3 system and the CORS network.It utilizes the NTRIP protocol to transmit monitoring data in real time,employs the precise point positioning (PPP)technology to calculate coordinates in real time,and uses GAMIT/GLOBK for static differential calculation,thus realizing millimeter-level deformation monitoring.On this basis,a real-time deformation monitoring system has been developed.Experiments show that the mean value of the normalized root mean square (NRMS)for baseline calculation over 60 days is 0.1917,and the repeatability precision is better than 2mm.The weighted root mean square (WRMS)of the coordinate time series is approximately 1mm,and the static calculation reaches the millimeter level.The horizontal precision of the dynamic calculation is 5mm and the vertical precision is 13mm.It has been verified that BDS-3 system can provide solutions for the monitoring of urban buildings and has engineering application value.
