卫星应用系统产品归档子系统的研究与实现

The study and implementation of a Satellite Product Archive System

本文介绍了一个卫星应用系统产品归档子系统,包含文件收集器、文件拷贝、任务收集器、元数据提取、产品数据归档以及元数据编目入库六个子模块。本系统采用以数据库为Server端,各个子模块为Client端的C/S结构。各子模块相互独立、松散耦合,通过灵活使用配置文件,实现系统分布式管理,提高了系统的可维护性和可扩展性。本系统已经成功应用于海洋一号卫星遥感数据归档过程中,同时对于同类卫星数据也有很好的适用性。

This paper introduces an automatically product archiving system of satellite application system.The system includes six modules, which are file acquiring module, file copying module, product data acquiring module, metadata extracting module, product data archiving module and metadata catalogue importing module.It implements C/S architecture, which takes database as the server and each module as the client.Those modules are loose-coupling, independent from each other, and could be configured flexibly, which contributes to the distributed management, maintainability, and expansibility of the system.The system has already been applied to the archive of HY-1B satellite remote sensing data.It can also be applied to the data archive of other satellites.
