Abstract

Large satellite development programs might take decades to build, launch and operate in space environments at costs in excess of a billion dollars. However, small satellites can reduce the costs not only by using commercial software and sensors, but also by shortening the development period to two years or less. In this paper, we discuss the development status of small satellites, and propose some military applications of small satellites. First, we describe the industrial trends of small satellites in advanced countries such as the United States and Japan. Also, we describe the development status of small satellites in Korea. Military applications are largely classified into education, research, and operational purposes. Small satellites are developing rapidly in commercial markets and they will play an important role in military sector. Therefore, the military should consider small satellites as important strategic assets in future conflicts and provide means to develop them.

대형 위성들은 수십억 달러가 넘는 개발 비용이 사용되고, 우주환경에서 운영하기까지 수십 년이 걸릴 수도 있다. 이에 비해 소형 위성은 상용 소프트웨어, 센서 등을 활용해서 비용을 절감할 수 있으며 개발 기간을 2년 이내로 단축시킬 수 있다. 본 논문에서는 이렇게 많은 이점을 가지고 있는 소형위성의 국내외 개발현황을 살펴보고, 소형위성을 군에서 활용하기 위한 몇 가지 방안을 제안한다. 먼저, 해외 개발현황으로 미국, 일본의 소형위성 개발현황을 소개하고, 국내 소형위성 개발현황을 소개한다. 군사적 활용방안은 크게 교육, 연구, 작전 분야로 분류하여 제안한다. 최근 소형위성은 상업 분야에서 빠르게 발전하고 있으며 향후 군에서도 중요한 역할을 할 것이다. 따라서 향후 스타워즈를 준비하고 있는 군에게 소형위성은 반드시 필요한 자산이며, 연구개발을 통해 지속적으로 발전시켜 나가야 한다.
