摘　　要：全球导航卫星系统(Global Navigation Satellite System,GNSS)数据下载是卫星导航定位实验教学的基础环节,决定后续相关实验能否顺利开展。在以往实验教学中,GNSS数据下载一般采用手动模式,存在操作繁琐、耗时长、易出错等问题,制约着实验教学质量的提高。基于HTTPS和FTP两类文件传输协议,采用Python语言开发了一款GNSS数据下载软件,设计了多线程下载、断点续传、异常处理等功能,实现了海量GNSS数据一键式下载。结果表明,在实验教学中采用开发的GNSS数据下载软件,解决了GNSS数据下载复杂繁琐的问题,更好地激发学生参与实验的积极性,提升实验教学质量。GNSS data download is the basic link of satellite navigation and positioning experiment teaching,which determines whether subsequently related experiments can be carried out smoothly.However,in the past experimental teaching,GNSS data download generally adopts manual mode,which has many problems such as tedious operation,time-consuming and error-proneness,leading to restrict the improvement of experimental teaching quality.Therefore,based on the HTTPS and FTP file transfer protocols,this paper uses Python language to develop a set of GNSS data download software,designed with functions such as multi-thread download,breakpoint transmission,exception handling,etc to achieve one-click download of massive GNSS data.The results show that the GNSS data download software developed in the experimental teaching is used to solve the complicated and tedious problem of GNSS data download,better stimulate students’enthusiasm for participating in the experiment,and improve the quality of experimental teaching.
