The NARO is South Korea's first carrier launch vehicle, which made its flights from NARO Space Center on 25 August 2009 and 10 June 2010. LV PACS(Preparation Automated Control System) is a electrical ground support system to monitor and control the integrated launch vehicle during the launch preparation and operation in Launch Complex. As a subsystem of LV PACS, LV PACS-II was developed for launch preparation and operation of the NARO upper stage, and all the functions and requirements were verified successfully through NARO flight tests. In this paper the core technology and characteristics applied to LV PACS-II are described.

This paper describes the operation results of the GPS receiver system for KSLV (Korea Space Launch Vehicle)-I on the launch site at Naro Space Center that is the first spaceport of South Korea located at Goheung. All equipments of KSLV-I including the GPS receiver system should be monitored and controlled through hard-wired interface during KSLV-I is on standby at the launch pad. The GPS receiver for KSLV-I is connected to triple almost omni-directional patch antennas mounted on the cylindrical surface of KSLV-I that should be erected vertically on the launch pad until lift-off. Signal interference and multipath effects observed in the GPS receiver on the launch site are analyzed in this paper based on the GPS signals received from each GPS antenna.

우주발사체의 개발은 대규모 자본이 들어가는 국가적 과제로 그 성공 여부는 물질적 측면을 떠나서 국가의 위상을 나타내고 국민에게 자부심을 부여하는 중요한 과제라 말할 수 있다. 발사체 개발의 성공을 위해서는 전체 시스템과 각 부속 시스템들의 신뢰성 확보가 반드시 필요하다고 말할 수 있다. 발사체 시스템을 구성하고 있는 부속 시스템중 발사 성공에 가장 중요한 역할을 하는 것이 추진기관이다. 따라서 신뢰성 있는 추진기관의 개발이야말로 전체 시스템의 신뢰도를 좌우하며 성공적인 로켓 발사를 이루기 위한 필수 요소라고 말할 수 있다. 본 연구에서는 과거 본 연구원의 과학로켓 개발 경험을 바탕으로 앞으로 진행될 소형위성발사체에 적용할 추진기관의 신뢰도 평가에 대하여 소개하고자 한다.

The flame deflector should be constructed to minimize the induced environmental effects on the launch vehicle and to minimize the exhaust impingement effects on the launch complex structures during the lift-off operation. Therefore, it should be designed to avoid recirculation and reverse flow of rocket exhaust plumes. The circumstance around launch complex and characteristics of launch vehicle should be taken into consideration for the flame deflector design. In this paper, we designed the flame deflector reflecting KSLV-II 1st engine characteristics and analyzed the effect of exhaust plumes related to change geometry by means of computational flow analysis.

To lunch the Korea Space Launch Vehicle-II(KSLV-II), the second launch complex will be constructed on the Naro Space Center and Kerosene Filling System (KFS) will be also installed newly. KFS of KSLV-II launch complex system is being designed based on Naro Launch Complex. But this must supply fuel to fuel tanks of the vehicle with only a supply pump because KSLV-II is a 3-stage launch vehicle unlike Naro Launch Vehicle or Test Launch Vehicle (TLV). A sudden rise of pump output pressure is recognized during fuel filling scenario selection process. This occurs because return flow can not actively deal with a lot of flow change using flow control method of orifice type. To solve this problem, it is verified that fuel can be stably supplied by installation of accumulator and an appropriate adjustment of filling mode change sequence through flow analysis of various cases.
