摘要
对龙羊峡GNSS监测系统的考察,发现现有的监测系统在实际使用中没有监测数据采集应执行的技术标准,数据采集与计算等全过程处理不规范等问题。文章以部分龙羊峡大坝监测网GNSS数据为研究对象,利用HGO、LGO等解算软件,从参数、策略模型、监测设计方面入手,进行数据处理模型优选研究。通过研究发现,解算参数中高度截止角、解算策略模型中星座星历、监测设计中时段组网等的选择使用为数据处理模型选择的重要因素。
Through the investigation of GNSS monitoring system in Longyangxia,it is found that the existing monitoring system has no technical standards for monitoring data collection in practice,and the whole process of data collection and calculation is inconvenient to manage and other problems.Taking part of GNSS data of Longyangxia Dam monitoring network as the research object,using HGO,LGO and other solving software,from the aspects of parameters,strategy model,monitoring design,data processing model optimization research is carried out.It is found that the selection and use of height cutoff Angle in the calculation parameters,constellations and ephemeris in the calculation strategy model,and time period networking in the monitoring design are important factors in the selection of data processing model.
