摘要
介绍了GPS时间序列数据处理及分析基本流程,对GPS时间序列数据处理及分析软件总体架构和模块功能进行设计,利用MATLAB平台并结合其图形用户界面(GUI),开发了GPS时间序列数据处理及分析软件。软件运行结果表明,该软件功能强,可靠性高,兼容性强,为GPS数据处理及时间序列分析领域人员提供了一个有力的工具。
This paper introduces the basic flow of data processing and analysis of GPS time series,and designs the overall structure and function mode of the GPS time series data processing and analysis software.The MATLAB platform and its graphical user interface（GUI）are used to develop the GPS time series data processing and analysis software.The software is designed with models,and it is integrated with correlation analysis,offset detection and PCA/Kalman filtering method,etc.Besides,it has data downloading and archiving,data preprocessing,spatial analysis,spatial filtering,time frequency analysis,coordinate time conversion and other related functions.Results show that the software is well-functioned,highly reliable,strongly compatible,and it provides a powerful tool for GPS data processing and time series analysis.
