Abstract

Units developed for a real satellite should pass space environmental tests and launch environment tests. Thermal Vacuum Test, one of the space environmental test, simulates extreme thermal environment encountered in on-orbit operation of satellite. Many payloads which adapt non-traditional, brand-new technology are developed by developers who is not familiar to space engineering field. There might be some possibility of mistakes which result in serious problem due to lack of experience, especially from planning to performing thermal vacuum test. In this paper, brief overview of thermal environmental test related to a satellite development is summarized in order to prepare and perform the thermal test.

인공위성 내부 유닛들이 위성에 실장 되기 위해서는 각 위성 프로그램에서 요구하는 다양한 환경시험을 반드시 통과해야 한다. 최근 타 분야의 기술이 우주분야로 이전되면서 다양한 인공위성 탑재체들이 개발되고 있다. 하지만, 타분야 개발자의 경우 우주개발에 대한 경험 및 이해부족으로 발사 및 우주환경시험을 수행함에 있어 다양한 문제점을 접하게 된다. 본 기술논문에 위성개발 각 단계에서 수행되는 열시험의 개념을 서술하여 우주분야 기술개발을 처음으로 수행하는 개발자가 열시험을 준비하는데 실제적인 도움을 주고자 한다.
