基于Python实现多源IGS数据快速获取
|
摘要
通过分析已有IGS数据获取程序存在的不足,结合现行IGS数据特点和数据处理需求,利用Python语言threading、ftplib、jdcal和gnsscal模块,编写IGS数据多线程快速获取程序,实现了多源IGS数据及产品的快速准确获取以及历史数据完好性和完整性检核,根据不同GNSS解算软件的数据组织结构、数据源、电脑性能和操作系统,实现快速定制和移植。通过运行测试,验证了程序的运行效率。
By analyzing the defects of existing programs,combining with the characteristics of the current IGS data and data processing requirements,using threading,ftplib,jdcal and gnsscal of the Python programming language module,write IGS data multithreading download program. This program can rapidly and accurately acquire multi-source IGS data and check historical data. According to data structure of different GNSS processing software,data source,computer performance and operating system,This program can achieve rapid customization and transplantation. the program efficiency is verified by operational testing.
