본 논문에서는 근지구 우주환경을 관측하기 위해 국내 최초로 4기가 편대비행으로 운용되는 6U 초소형위성 SNIPE(국문명 도요샛; small scale magnetospheric and Ionospheric plasma experiment )의 본체(BUS) 설계 내용과 개발 과정에 대해 기술하였다. SNIPE는 지구 주위 우주환경을 입체적으로 관측하기 위해 4기가 편대비행을 수행하며, 전리권에서 우주 플라즈마 밀도 및 온도, 그리고 태양 자기장과 전자파 등의 시간적 변화를 동시에 관측한다. 임무 기간은 최소 6개월 이상으로 신뢰성을 높이기 위해 시험인증모델(EQM)과 비행모델(flight model, FM)으로 나누어 개발하였다. 현재 총 4기의 비행모델의 개발을 완료하고 우주환경시험을 모두 마친 SNIPE는 2023년 발사 예정이다. 본 논문에서는 발사를 앞둔 SNIPE 위성 본체의 설계 내용과 개발 과정을 소개하며, 향후 국내에서도 본격적인 임무 수행을 위한 6U급 초소형위성 개발에 유용한 참고 자료가 되기를 기대한다.

In this paper, the contents of the design and development process of the 6U micro-satellite Snipe (SNIPE, national name Toyosat; small scale magnetospheric and Ionospheric plasma experiment ), which was developed to observe the near-global space environment through polarization flight for the first time in Korea, were described. Snipe performs transversal flight to observe the Earth's surrounding space environment in three dimensions, and aims to simultaneously observe the space plasma density and temperature in the ionosphere, as well as temporal changes in the solar magnetic field and electromagnetic waves. In this way, it was developed by dividing it into a test certification model (EQM) and a flight model (FM) to perform the actual mission for at least six months, away from developing a cube satellite for short-term space technology verification or manpower training. Currently, Snipe, which has completed the development of a total of four FM and completed all space environment tests, is scheduled to launch 2023. In this paper, we introduce the design contents and development process of the Snipe satellite body ahead of launch, and hope that it will be a useful reference for the development of 6U-class micro-satellite for full-scale mission in Korea.
