Abstract

The purpose of this study is to propose a mid - range low - orbit water disaster monitoring satellite development plan to revolutionize water disaster management infrastructure through securing an independent and leading observation infrastructure and to secure safety against disaster prepared for climate change. Water and water disaster satellites should be able to detect changes in the surface of the ground and observe hydrological factors during daytime, nighttime, and bad weather. In addition, independent technology development should be possible. To do this, we selected C-band image radar payload considering domestic technology and water resources management, and suggested detailed development plan. In this way, it is reflected in the national next-generation mid-satellite 2-phase project plan to secure the basis for building a disaster monitoring system related to wide-area water.

전 세계적으로 홍수와 가뭄 발생 빈도는 가파르게 증가하고 있고, 태풍 및 가뭄 발생 빈도도 꾸준히 증가하고 있어 광범위한 관측과 정확한 예측, 즉각적 대처 능력 확보를 위한 수자원 관리 기술 확보가 필요하였다. 이를 위해, 본 연구에서는 독립적이고 주도적인 관측인프라 및 분석 기반 확보를 통해 수재해 관리 기반을 획기적으로 혁신하고, 기후변화에 대비한 물안보 및 재해로부터 안전성을 확보하기 위하여 저궤도 수재해 감시 중형급(500kg이하) 위성 개발 방안을 제시하고자 하였다. 수자원 수재해 위성은 주야 및 악천후에도 지표면의 변화탐지 및 수문인자 관측이 가능할 뿐만 아니라, 독자적인 기술 확보기 가능한 C밴드 영상레이더 탑재체 및 시스템을 선정하여 세부적인 개발 방안을 제시하였다. 이를 통해 국가가 추진하는 차세대중형위성 2단계 사업 계획에 반영하여 광역 물 관련 재해 감시 체계 구축을 위한 기반 확보가 가능하게 되었다.
