ARIETIS – 내방사선 자이로스코프


ARIETIS ITAR의 제한을 받지 않는 우주급으로 검증된 내방사선 자이로스코프로 Hi-Rel class 1 부품을 사용합니다. 주요 응용분야는 LEO, MEO, GEO (저/중/정지 위성), 통신  및 탐사 위성의 주 자이로스코프 또는 Coarse rate sensor 입니다. ARIETIS는 ESA(European Space Agency) 의  ECSS(European Cooperation for Space Standardisation) 에 따라 개발및 검증되었고 우주 산업분야의 규격에 따라 고품질의 요구사항을 만족합니다.
