摘要
着重介绍了GPS数据的单历元解算方法,以及监测点变形量的分析和预测,探讨了这种方法在变形监测系统数据处理中的应用情况及数据相关性对变形精度的影响。阐述了对变形量进行分析和预测的各种方法,提出用整体方差法对变形量进行分析,并用卡尔曼滤波方法对变形值进行预测,试算结果表明这些方法是可行的。最后,设计了一套GPS自动变形监测系统,包括软件功能设计、数据库实现等,并对系统安全性和可靠性进行了分析。
This paper focuses on the introduction of single epoch resolution of GPS data, and the analysis and forecast of deformation value of the monitor point. It discusses the application status of the technique in deformation monitoring data processing and the influ- ence of data correlation to deformation accuracy, explores the various kinds of methods of analyzing and forecasting deformation value, puts forward the overall variance methods of analyzing deformation value, and forecasts the deformation value using Karlman filtering method. The calculating result proves that these methods are practicable. At last, the authors design a kind of automatic GPS deforma- tion value monitoring system which covers software function design and database implementation, and analyze the security and reliabili- ty of the system.
