基于北斗/GNSS高精度定位技术进行区域地块地面沉降监测和预警研究

Research on monitoring and early warning of regional land subsidence based on BeiDou/GNSS high-precision positioning technology

在进行区域土地测量地面沉降监测时,遥感技术因其数据滞后不能满足实时性要求,因此需要采用新的监测方法。北斗三号全球卫星导航系统于2020年7月31日正式开通,可在全球范围内提供高精度导航、定位、授时和短报文通信服务。本文通过北斗/GNSS高精度测量技术进行实际场地上的定位、测区范围内的地面沉降监测和预警,设计相应的方案来实现对地面实时动态信息的处理分析研究,以确保其精确性和可靠性,从而提高地面沉降监测和预警的工作效率。

When monitoring land subsidence in regional land survey,remote sensing technology can not meet the realtime requirements because of its data lag,so it is necessary to adopt new monitoring methods.The Beidou-3 Global Navigation Satellite System,which opened on July 31,2020,can provide high-precision navigation,positioning,timing and short message communication services worldwide.In this paper,the high-precision beidou/GNSS measurement technology is used to locate the real site,monitor and early-warning the land subsidence in the survey area,and the corresponding scheme is designed to process and analyze the real-time dynamic information of the ground,to ensure its accuracy and reliability,so as to improve the efficiency of land subsidence monitoring and early warning.
