Abstract

Over the past half century, satellites have continuously expanded their roles in remote sensing applications. As the number of satellites to be launched are expected to continuously increase in coming years, the research on satellite payloads will be in high demands. Earth Observation (EO) satellites are nowadays widely utilized for various purposes. Especially, Agriculture and forestry applications are considered as their major application areas. Since about 85% of domestic land cover is classified as forest or cropland areas, it would be reasonable to suggest that the demand for these satellites should be of high priority. In this paper, a comprehensive analysis is performed on the technical specifications of satellite payloads that may be applicable to agricultural applications. We attempted to build a solid database on payload specifications by collecting relevant information available from various related institutes and academic research works. A number of experts involved in national agricultural research and satellite development programs have been invited to investigate required payload design. Based on the current technology development status and future plan, multiple options for future satellite payload designs have been suggested bearing in mind that the results may be applicable to the future agriculture and forestry satellite payload design. The proposed payload specifications are analyzed in depth through satellite operation simulations under the mission of observing the national agriculture areas. The proposed design scheme and simulation results may be used as technical references to satellite payload design for future space missions.

위성은 지난 반세기 동안 활동영역을 넓혀왔고, 향후에 추가 발사될 것으로 전망됨에 따라 위성 탑재체 개발에 대한 연구는 활발히 증가될 것으로 예측된다. 특히 지구관측 위성은 사용 목적과 수요에 따라 다양한 분야에서 활용되고 있으며 각 활용분야에 따른 적합한 탑재체 제원이 필요하다. 한반도의 경우 국토의 85%가 산림 및 농경지로 분포되어 있어 농림업 분야에서의 활용이 가장 활발할 것으로 예측할 수 있다. 본 논문에서는 향후 농림업분야에서 국내 지형을 효율적으로 관측하기 위한 위성 탑재체 기술을 분석하였다. 이를 위해 국내 사용자들이 농림업분야에 위성영상을 활용한 사례를 조사하여 관측 탑재체의 기술특성에 대해 분석하였다. 또한 국내외에서 농림업분야에 활용되고 있는 지구관측 위성 탑재체의 개발 현황과 향후 국내 지형을 효율적으로 관측하기 위한 기술사양을 분석하였다. 이를 바탕으로 관측폭 조정과 탑재체 관측 운용 형태에 따른 위성 모의 운용실험을 수행하였다. 본 연구 내용은 향후 농림업 위성이 개발에 앞서 기술적 참고 자료로 활용될 수 있을 것으로 기대된다.
