The Design and Implementation of the HY-1B Product Archive System

摘要

HY-1B satellite, which is followed by HY-1A satellite, is hosted by the National Satellite Ocean Application Service of China. As the center for data management of the Ground Application System of HY-1B (GAS), the Product Archive and Distribution System (PADS)is responsible for improving the efficiency of data management, reducing the complexity of man-made operation, ensuring the whole system's reliable running and enhancing the level of services for the end-user. Product Archive System (PAS), as a background system, is the core part of PADS. This paper describes the seven major components of the PAS (Network Communicator module, File Collector module, File Copy module, Task Collector module, Metadata Extractor module, Product data Archive module, Metadata catalogue import module)and some of the unique features of the system, technical problems encountered and resolved.
