- Abstract
- The meteorological satellite, GEO-KOMPSAT-2A, equipped with Advanced Meteorological Imager (AMI) is going to be prepared for observing weather information of the earth and the space in Korea. GEO-KOMPSAT-2A will collect large amounts of data and transmit them to the ground segment in charge of weather data processing and management. The system configuration and deployment of ground segment have been studied until now and the system requirements of each system have been defined. The system design phase will be started from 2015. The satellite Data Management and Service System discussed in this paper is one of the systems which consists the ground segment for GEO-KOMPSAT-2A. The system will manage all of satellite raw and processed data and serve them to various users who need it. The satellite Data Management and Service System will be located in both primary and backup sites for redundancy. To design the architecture of the Satellite Data Management and Service System, first the amount of data to be stored for whole mission life was assumed and secondly system configuration for reliable data service was considered. Also, the interface with other systems included in ground segment has been defined for the appropriate operations among them. The Satellite Data Management and Service System is composed of the Satellite Data Management Subsystem and the Satellite Data Service Subsystem. The Satellite Data Management Subsystem will be designed considering the archive period, the frequency of use, backup and restore, and so on. The Satellite Data Service Subsystem will provide web services for internal users and for external users, and user customized service providing FTP, Web download and Open API services. In this paper, the architecture of the Satellite Data Management and Service System will be presented and discussed.
