Data Processing and System Design of Construction Deformation Monitoring Based on GPS

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 influence 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 deformation value monitoring system which covers software function design and database implementation,and analyze the security and reliability of the system.
