Abstract

In this paper, we have surveyed the existing architectures of the image processing systems for several meteorological satellites and identified issues which are taken into consideration to construct the advanced meteorological satellite image processing system that is being developed by NMSC(National Meteorological Satellite Center). Most of the existing systems provide the functionalities of the image acquisition, the image processing, the data management, and the data dissemination. Those systems have some common problems with respect to system integration and system maintenance. To solve these problems, NOAA, NWS and ESA suggest new system architectures to improve the existing systems. This paper introduces domestic and foreign approaches to build the satellite image processing systems and studies some issues and strategies for developing those systems.

본 논문에서는 기존에 구축되어있는 위성영상처리 시스템의 구축현황을 살펴보고, 향후 국내 기상위성 영상처리 시스템 구축에서 고려해야할 사항에 대해 살펴본다. 기존의 위성영상처리 시스템은 운영 중인 개별 위성에 대한 영상의 수집, 처리, 배포 기능을 구현한 시스템이 대부분이었다. 그러나 향후 지구환경 감시를 위한 다양한 위성들의 개발에 따른 새로운 시스템의 통합, 기존 시스템에 대한 유지보수에 대한 문제점이 지적되고 있다. 미국의 NOAA, NWS, 유럽의 ESA등에서는 이러한 문제점을 해결하기 위해 기존의 시스템에 대한 개선 사업을 진행 중에 있다. 이에 본 논문에서는 현재 국내외에서 개발되는 위성영상처리시스템의 구축 현황을 살펴보고, 개발 이슈 및 개발 전략에 대해 살펴보고자 한다.
