  • Korea's space activity is expected more vital in the next decade. 14 Korean government satellites, with 10 satellites more over the last decade, are planned for launch between 2011 and 2020 according to the national space long-term plan. And Korean Space Launch Vehicle 2 has been developing aiming to launch in 2021. Forecasting and supply planning for the Korea Aerospace Research Institute's manpower could be essential to successfully fulfill the Korea's next decadal task in the aerospace field. In this paper, KARI's manpower is forecasted using the relations between KARI's budget and total personnel. KARI is expected to has 1,000~1,400 personnel in 2020 which is at least 400 personnels more than present.

  • 정지궤도 복합위성용 전력조절장치는 위성의 전력버스에 필요한 전력을 조절하고 배터리의 충전과 방전을 제어하고 관리한다. 전력조절장치의 용량은 1kw로 하고 태양 전지의 어레이는 4개의 패널로 구성되며 S3R(Sequential Switching Shunt Regulator)을 이용하여 조절된 버스전압은 완전조절 50Vdc으로 한다. 변환된 전력은 위성부하에 필요한 전력을 분배하는 PDM(Power Distribution Module)에 공급된다. 남은 전력은 BCR(Battery Charge Regulator)를 통해 배터리에 전력을 충전하고 전력이 부족할 때 BDR(Battery Discharge Regulator)를 통해 방전을 하여 버스전압에 전력을 공급한다.
