IGS产品批量、定时、自动下载软件设计与实现

Software Design and Implementation for IGS Products Batch,Timing and Automatic Download

随着全球GNSS的发展以及IGS自身的不断完善,IGS产品精度不断提高、应用更加广泛,广大用户对IGS产品的要求也在不断增长,下载日益频繁。IGS通过文件传输协议服务实现IGS产品的发布,人工下载步骤烦琐,费时费力且容易出错,文中利用C#语言开发了IGS产品的下载软件,实现了相关文件的批量、定时、自动下载,有助于减轻工作人员的负担,提高工作效率,而且能够在文件发布后及时下载,减少错误发生的概率。通过对2015年9月份不同发布周期、不同类型文件的下载,证实了本软件进行IGS产品下载的可行性。

With the development of GNSS and the continuous improvement of IGS,IGS products are more precise and widely used.Users＇ requirements are also growing,and downloading GNSS products happened frequently.IGS via File Transfer Protocol service release their products.Artificial download is cumbersome,time-consuming and error-prone.In this paper,a software is designed to download products of IGS by using C#,achieving batch timing and automatic downloading.It helps to reduce the burden of the staff,improve work efficiency,download the file timely and reduce the probability of errors occurring.By successfully downloading files of different types and cycles that released in September 2015,it can be confirmed the feasibility of this software on downloading IGS products.
