Abstract

This paper introduces the case studies of launch environmental test for cube nanosatellites and lessons learned of the design and integration from those. Generally, nanosatellites are launched and deployed in space while being contained in nanosatellite deployers, mechanical loads of launch are transferred through the deployer. This characteristic make nanosatellites under larger loads and higher possibilities of mechanical failure. This study represents guidelines of the design and the integration of the nanosatellites by showing the cases of launch environmental test of nanosatellite system. Moreover, it is suggested that the modern nanosatellite deployer with the capability of fixing the internal nanosatellite be preferable to conventional deployer by comparing the test results with those deployers.

본 논문은 나노급 큐브위성 시스템 및 유닛의 발사환경시험 사례를 통해 얻을 수 있는 설계와 제작의 교훈들을 소개한다. 일반적으로 초소형위성은 발사관에 담겨 발사되므로 발사 시 외부 하중 역시 발사관을 통해 내부의 위성에 전달된다. 이러한 특성으로 인해 초소형위성은 외부 가진에 비해 과도한 하중을 받을 수 있고 기계적 파손의 가능성을 높인다. 여기서는 진동시험 사례를 통해 초소형위성 설계와 제작 시 지켜야 할 여러 지침들을 보여준다. 그리고 내부 위성을 고정하는 현대적인 기능이 적용된 발사관과 전통적인 발사관의 시험 결과를 비교함으로써 발사관 선정에도 하나의 권고를 제시한다.
