초록

극초소형 위성으로 분류되는 큐브위성 STEP Cube Lab.(Cube Laboratory for Space Technology Experimental Project)은 우주기반 핵심기술들의 궤도검증을 주 임무로 2015년 발사를 위해 최종 비행모델의 개발을 완료하였다. 상기 임무를 위해 STEP Cube Lab.은 수동 열제어를 기반으로 최적화된 열제어 설계를 수행하였으며, 수락(acceptance) 수준의 열진공시험을 통해 위성 성능 및 열제어 설계의 검증을 완료하였다. 또한 열평형 시험을 통해 위성 열-수치 모델의 신뢰도 향상을 위한 보정 작업을 수행하였다. 본 논문에서는 STEP Cube Lab. FM의 열진공시험을 통한 일련의 검증 과정에 대해 서술하고자 한다.

The STEP Cube Lab. classified as a pico-class satellite has been successfully developed as a flight model(FM) to be launched in 2015. Its mission objective is to perform the on-orbit verification of fundamental space core-technologies. In this study, a thermal design concept based on the passive method to achieve the mission objective is introduced. The effectiveness of the thermal design and performance of the satellite has been verified through the acceptance level thermal vacuum test. In addition, to improve the reliability of thermal mathematical model, correlation was performed using the results of thermal balance test. This paper describes a series of process for the thermal vacuum test on the STEP Cube Lab. FM.
