Abstract

In this paper, the New Space characteristics and response of micro & small satellite, and space industrialization strategy using domestic technologies are described. Recently, micro & small satellites are developed worldwide, including Starlink, having the characteristics of low-cost, light-weight and satellite constellation. Therefore, it is necessary to prepare for the constellation operation by considering the use of Commercial Off-The-Shelf (COTS) parts, satellite weight, shape and mass production. In particular, it is necessary to develop Multi Input Multi Output (MIMO) technology in consideration of the frequency interference during constellation operation, and to prepare and make efforts to secure frequencies in the government. Among the commercial-grade memories of Samsung Electronics and SK Hynix, the space-grade memory field using radiation tolerant memory and the high reliable packaging and space environment test technology has potential as a space industrialization strategy.

본 논문에서는 (초)소형위성의 뉴스페이스 특징 및 대응방안을 소개하고, 국내기술을 활용한 우리나라의 우주산업화 전략을 제시한다. 최근 스타링크를 포함하여 전세계적으로 개발되는 (초)소형위성들은 저비용 및 경량의 군집위성 특징을 가지고 있으므로, COTS(Commercial Off-The-Shelf) 부품 사용 및 위성 중량, 형상, 대량생산 등을 고려하고 군집운용을 준비해야 한다. 특히 다중위성 운용시 주파수 간섭을 고려하여 MIMO(Multi Input Multi Output) 기술 개발 및 정부 차원의 주파수 확보를 위한 준비와 노력이 필요하다. 삼성전자와 SK하이닉스의 상용급 메모리 중에서 내방사선성이 좋은 메모리와 중소기업의 고신뢰성 패키징 및 우주환경시험 기술을 이용하는 우주급 메모리 분야는 우주산업화 전략으로 가능성이 있다.
