India and China are capable of developing indigenous space launch vehicles, with the rocket technology transferred from the U.S., Western countries, and the Soviet Union, in the 1950s and 1960s. Barring the early 1990s, both countries are absent in the missile nonproliferation regime, and have no major space cooperation records with the U.S., since the establishment of the Missile Technology Control Regime in 1987. With the advent of the $21^{st}$ century, historic progress has been made in the U.S.-India space cooperation, which includes using Indian launch vehicles to launch U.S.non-commercial satellites. However, the U.S. is skeptical with regards to space cooperation and using Chinese space launch vehicle services. In this paper, we present the U.S. nonproliferation policy applied on launch vehicles of India and China, and different aspects of the policy will be examined to draw implications on Korean space activities.

We report on the design of a three-axis missile autopilot using multi-objective control synthesis via linear matrix inequality techniques. This autopilot design guarantees $H_2/H_{\infty}$ performance criteria for a set of finite linear models. These models are linearized at different aerodynamic roll angle conditions over the flight envelope to capture uncertainties that occur in the high-angle-of-attack regime. Simulation results are presented for different aerodynamic roll angle variations and show that the performance of the controller is very satisfactory.

한 나라의 우주개발은 막대한 예산과 많은 시간이 소요되기 때문에 정부주도로 연구개발사업을 시작하는 것이 대체적인 선례이다. 하지만 때로는 우주개발을 지역사회나 주변 국가들과의 상황에 따라 생존을 위한 방편으로도 활용될 수 있다. 이러한 우려를 불식시키거나 완화하자는 차원에서 국제사회가 다자간 협의체인 미사일기술통제체제(MTCR, Missile Technology Control Regime)을 1987년부터 시작하여 매년 총회 및 회기간 회의를 통하여 국제사회에서 대량파괴무기의 운반체로 미사일이나 무인항공기 등과 관련된 시스템 및 부품 등의 기술이전 등에 관하여 규제를 하고 있는 것이다. 최근 국제사회에서 핵 프로그램 및 미사일 문제로 논쟁의 핵심이 되고 있는 이란에 대하여 우주개발과 미사일기술통제체제의 규제 등의 관점에서 본 논문을 검토하고자 한다.

우리 나라는 90년대에 들어서 향후 2015년까지 세계 10위권의 선진우주국에 진입한다는 우주개발중장기목표를 설정하고 중간 추진단계로서 2005년까지 국내기술에 의한 저궤도위성 및 발사체를 개발한다는 목표를 세우고 있다. 그리고 이를 위한 구체적인 시행 프로그램으로서 KSR-I및 KSR-II사업을 추진하여 성공적으로 완료하였으며, 이제 2002년까지 KSR-III사업으로 3단형 액체추진로켓을 개발 중에 있다. 현재 세계 우주 발사체 시장은 저궤도위성의 수요가 급증함으로서 전 세계적으로 저가의 우주발사체 개발을 서두르고 있으며, 우주선진국들은 경쟁적으로 기술혁신을 추진하고 있다. 그러나 개발도상국가들이 이에 참여하는데 있어서는 G7선진국들이 이미 마련한 MTCR(Missile Technology Control Regime)규제에 의거 기술이전 및 부품수입이 어렵기 때문에 자력에 의한 발사체 개발이 불가피하다. 본 고에서는 우주발사체 주요 선개발국 8개국의 기술혁신 과정과 정책 및 추진체계 등을 분석하고, 국내 발사체 개발에 참여하고 있는 주요 7개 민간기업을 대상으로 실시한 설문조사와 현장 실태조사를 바탕으로 기술혁신을 촉진하는 구체적인 정책대안 및 목표년도에 성공적인 발사를 위한 개선방안을 제시하였다.

The missile technology and its development in south Korea have been restrained to the limit of 180 km by America which instead provided to Korea with security protection. In the same vein, America pressured South Korea to abort its nuclear weapons program so as to prevent another possible military encounter that can easily develop into a war between South and North Korea. This restraint was a bit relaxed when South Korea joined the Missile Technology Control Regime (MTCR) in 2001 whereby the limit was 300 km. The situation of South Korea is in much contrast with its neighbor, North Korea, which has fired Taepo Dong 1 and Taepo Dong 2 to put its alleged satellite respectively into the Earth orbit. The range of this rocket believed to be reaching more than 5,500 km, a range of the intercontinental ballistic missile, without any rein. South Korea that has just geared its full powers for its outer space industry, with the current space projects of putting its satellites into the low Earth orbit, will in future put its satellite into the geostationary orbit, 36,000 km above the Earth. To do so, such restraint had better be resolved. Korean space industry, as it is alike in other countries, started with putting and manufacturing sounding rockets, producing satellites but relying on foreign launching facilities, and learning launching capacities. Experiencing three time launchings of KITSAT, the current satellite projects of Korea are undertaken as follows: - Koreasat - STSAT - Komsat - MBSAT - COMS (Communication, Ocean, and Meteorological Satellite) Koreans waked up to the things of outer space in 2008 with the first Korean astronaut Li So-yeon, a lady bio systems engineer. Although the first Korean made rocket in cooperation with a Russian company to fire last August 2009 was a failure, it should be considered as an inevitable process for future endeavors. There are currently three outer space related laws of Korea: Aerospace Industry Development Promotion Act 1987, Outer Space Development Promotions Act 2005, and Space Damage Compensation Act 2008. The first two stemming from the two different ministries are, however, overlapping in many aspects and have some shortcomings to be improved.
