摘要
针对我国西南流域高山峡谷复杂的卫星观测环境,大型水电工程监测控制网精度和可靠性不足的难题,提出基于北斗的监测体系构建方法,通过环境误差与多路径误差建模提高测点的监测精度,并基于该关键技术和支撑服务目标研发了北斗亚毫米级超高精度监测一体化应用平台,解决了水电工程复杂环境下卫星定位高精度监测的难题。
In response to the complex satellite observation environment of high mountains and canyons in southwestern China,and the problem of insufficient accuracy and reliability of deformation monitoring and control network measurement results for large-scale hydropower projects,a monitoring system construction method based on Beidou is proposed.By modeling environmental errors and multipath errors,the monitoring accuracy of measurement points is improved.Based on the above key technologies and supporting service objectives,a Beidou sub-millimeter level ultra-high precision monitoring integrated application platform is developed to solve the problem of high-precision satellite positioning monitoring in complex environments of hydropower projects.
