우주개발프로그램에서의 전기지상지원장비 개발 동향

Once the spacecraft are launched, it is almost impossible to bring back and repair them again. At this point of view, the AIT (Assembly, Integration and Test) on the ground before launch is very important for all of space programs. Usually, it takes several years and more for thorough examinations because it totally depends on the complexity of the space program. In today"s environment, as demands of cost effective and reliable spacecraft increase, there have been a lot of researches supporting it. Removal of duplicated work, design of efficient test procedure and re-use of test equipments can be good examples. This paper is aimed at describing the recent trends and technologies about electrical ground support equipments in several advanced countries.
