UN과 우주 강국을 중심으로 위성을 활용한 국제협력이 강화되고 있는 추세임. 특히 미국과 유럽 등 전통적인 해양 강국은 위성의 해양 분야 활용도를 확대하고 있으며 국제 협력도 구체화하고 있음. 'Space Rush'와 'Ocean Rush'에 이은, 우주와 해양의 통합 관리체제를 통한 새로운 해양강국 출현의 시대로 접어들 가능성도 있음다. 이번 논문에서는 우주 강국인 일본이 추진하고 있는 우주와 해양 융 복합 전략을 분석하였음. 이를 위해 일본의 해양과 우주의 행정 협업, 우주기본계획 중 해양분야, 제2차 해양기본계획 중 우주(위성 분야), 해양 분야 인공위성 활용 사례 및 국제 협력 사례 등을 제시하였음. 일본의 해양 분야 위성 활용과 위성을 활용한 국제 해양 협력은 향후에도 지속되고 확대될 것으로 판단됨.

1995년 한국 최초로 VLBI관측이 이루어졌다. 일본 측의 26m 안테나(일본 국토연구원 소재)와 한국 측의 3.6m 안테나(국토지리정보원 소재)로 수행되었으며, 이 때 결정된 관측점의 좌표가 세계 공통으로 사용되는 "세계측지계(ITRF)"에 의거한 새로운 국가기준좌표계의 경위도 원점이다. 그 후 측지VLBI관측국의 설치를 위해, "측지VLBI구축 타당성조사 및 기본계획 수립을 위한 연구(2003년)"와 "측지VLBI구축 실시설계(2006년)"를 수행하였다. 그 결과 국가 차원에서 측지VLBI관측소(22m 안테나)를 건설하기 위해 2008년에 관측소 후보지를 세종시로 확정해서 공사에 들어갔다. 2012년에 준공되었으며, 명칭을 "우주측지관측센터"로 하였다. 그 후 1년 동안의 시험관측의 성공으로 아시아에서 3번째로 정식으로 IVS(International VLBI Service)에 가입하였다. 현재 독일, 일본, 미국 등의 측지VLBI관측국들과 정기적으로 관측을 수행하게 되었으며, 실적을 올리고 있다. IVS사업 뿐 만 아니라, 한국천문연구원의 KVN(천문 VLBI)연구팀과도 공동연구를 수행해서 우리나라의 천문 VLBI 및 측지VLBI관측사업의 활성화에 기여하고 있다. 장차 동남아 각국에 마이크로SAR위성의 관측데이터를 수신하기 위한 지상국(3m급 소형안테나)이 설치되면, 이를 활용해서 측지VLBI관측을 수행할 계획을 수립하고 있다. 이것은 위성용 수신기를 VLBI용 수신기로 교체하면 된다. 한국과 일본이 VLBI관측을 수행했던 것처럼 세종시에 설치된 우주측지관측소가 허브역할을 하면 된다. 즉 동남아 지역에 우주 VLBI관측망을 구축하게 된다.

In 2014, Japan is scheduled to launch GCOM(Global Change Observation Mission)-C for the global change observation mission, where SGLI(Second-generation Global Imager) is planned for optical multi-channel observation ofa radiation budget and a carbon cycle. Depending on the spectral channels, SGLI consists ofS GLI-VNR(Visible Near IR) and SGLI-IRS(IR Scanning). Their main design schemes are mostly based upon those ofthe previous instruments ever developed in Japan, which is intended to reduce the development risk for the advanced performance. Accordingly, for the better understanding ofSG LI, the paper reviews the history oft he Japanese optical payloads from two different views: VNR and IR. Through the review, a comparison among the Japanese optical instruments is made to distinguish the development trend toward SGLI ofGC OM-C.

전파자료처리를 위한 전파분광기는 전파망원경으로 얻어진 우주전파자료를 최종 처리하는 장비이다. 현재, 전파관측에서는 우주의 미세구조를 밝혀내기 위해 관측자료의 대량화와 고속화가 진행되고 있는데, 이러한 초고속 대용량 자료를 처리하기 위해서 FPGA나 ASIC 등으로 구성된 하드웨어 기반의 전파분광기를 주로 사용하고 있다. 그러나, 하드웨어 기반의 전파분광기는 개발에 시일이 많이 소요되고 고가이며 수정 변경이 쉽지 않다. 한편, 관측자료는 더 대량화되고 고속처리가 필요한 추세로 가고 있다. 이러한 한계를 극복할 수 있는 방법 중 하나가 고속 계산 플랫폼을 기반으로 구현되는 소프트웨어 전파분광기이다. 미국, EU, 일본 등은 이러한 전파분광기 개발을 이미 진행하고 있다. 특히, THz 대역에서 관측시스템 개발을 이제 막 시작하는 우리나라로서는 경쟁력을 갖추려면 외국의 기술의존성을 탈피하고 첨단의 초고속 관측자료처리 기술을 확보해야 한다. 이를 위해 국내의 우수한 IT기술을 전파관측기술에 활용하여 단계적으로 기술을 발전시킬 필요가 있다. 본 연구는 고속 계산 플랫폼을 기반으로 구현되는 소프트웨어 광대역 전파분광기의 기술개발에 관한 것으로 전파관측에 적용할 수 있는 x-엔진 개발과 기술 결합에 중점을 두고자 한다. 이에 소프트웨어 광대역 전파분광기의 기본 설계 및 향후 계획을 소개한다.

The purpose of this paper is to research on the contents and improvement of national legislations relating to space development in Korea to make the sustainable progress of space development project in Korea. Korea has launched its first satellite KITST-1 in 1992. The National Space Committee has established "The Space Development Promotion Basic Plan" in 2007. The plan addressed the development of total 13 satellites by 2010 and the space launch vehicle by 2020, and the launch of moon exploration spaceship by 2021. Korea has built the space center at Oinarodo, Goheng Province in June 2009. In Korea the first small launch vehicle KSLV-1 was launched at the Naro Space Center in August 2009, and its second launch was made in June 2010. The United Nations has adopted five treaties relating to the development of outer space as follows : The Outer Space Treaty of 1967, the Rescue and Return Agreement of 1968, the Liability Convention of 1972, the Registration Convention of 1974, and the Moon Treaty of 1979. All five treaties has come into force. Korea has ratified the Outer Space Treaty, the Rescue and Return Agreement, the Liability Convention and the Registration Convention excepting the Moon Treaty. Most of development countries have enacted the national legislation relating to the development of our space as follows : The National Aeronautic and Space Act of 1958 and the Commercial Space Act of 1998 in the United States, Outer Space Act of 1986 in England, Establishment Act of National Space Center of 1961 in France, Canadian Space Agency Act of 1990 in Canada, Space Basic Act of 2008 in Japan, and Law on Space Activity of 1993 in Russia. There are currently three national legislations relating to space development in Korea as follows : Aerospace Industry Development Promotion Act of 1987, Outer Space Development Promotion Act of 2005, Outer Space Damage Compensation Act of 2008. The Ministry of Knowledge Economy of Korea has announced the Full Amendment Draft of Aerospace Industry Development Promotion Act in December 2009, and it's main contents are as follows : (1) Changing the title of Act into Aerospace Industry Promotion Act, (2) Newly regulating the definition of air flight test place, etc., (3) Establishment of aerospace industry basic plan, establishment of aerospace industry committee, (4) Project for promoting aerospace industry, (5) Exploration development, international joint development, (6) Cooperative research development, (7) Mutual benefit project, (8) Project for furthering basis of aerospace industry, (9) Activating cluster of aerospace industry, (10) Designation of air flight test place, etc., (11) Abolishing the designation and assistance of specific enterprise, (12) Abolishing the inspection of performance and quality. The Outer Space Development Promotion Act should be revised with regard to the following matters : (1) Overlapping problem in legal system between the Outer Space Development Promotion Act and the Aerospace industry Development promotion Act, (2) Distribution and adjustment problem of the national research development budget for space development between National Space Committee and National Science Technology Committee, (3) Consideration and preservation of environment in space development, (4) Taking the legal action and maintaining the legal system for policy and regulation relating to space development. The Outer Space Damage Compensation Act should be revised with regard to the following matters : (1) Definition of space damage and indirect damage, (2) Currency unit of limit of compensation liability, (3) Joint liability and compensation claim right of launching person of space object, (4) Establishment of Space Damage Compensation Council. In Korea, it will be possible to make a space tourism in 2013, and it is planned to introduce and operate a manned spaceship in 2013. Therefore, it is necessary to develop the policy relating to the promotion of commercial space transportation industry. Also it is necessary to make the proper maintenance of the current Aviation Law and space development-related laws and regulations for the promotion of space transportation industry in Korea.

Space technology is a core technology which is emerging as the most competitive industry in the 21st century. However, it is said that private enterprises may have some limitations to run the space business independently because the space industry requires not only to enormously spend the amount of investment at the beginning stage of business but also to have lots of difficulties to get the amount of investment in the short period of time. Therefore, the advanced countries of having the space industry such as America, Japan, France and so on have been developing the space technologies through the help of their governments to some level at the beginning stage of business. Korea established the space development promotion law in 2005. Also Korea has been making efforts to correct the national space development middle and long term basic plans. However, while Korea becomes the 8th economic country in the world, Korea does not have a large enterprise which has ability to supply the domestic satellite demands, and to export satellites to foreign countries by developing satellites without having any help from foreign companies. Therefore, this paper described the activating scheme of satellite industry to efficiently carry out the Korea's space development mission, and to enforce the global competitive power.

The Korean government established her first "National Space Program" in 1996, and revised it in 2000 and 2005. As embedded in the National Space Program, Korea aims to become one of the world's top countries in space technology by 2010. All of 13 satellites are planned to be put into orbit as schematized, which include 7 multi-purpose satellites, 4 science satellites and 2 geostationary orbit satellites. The Space Center in Korea is to be built at Woinara-Do, Bongrae-Myon, Koheung-Goon, Junlanam Province on the southern coast of the Korean peninsular. The first phase of the construction of the space center will be finished by 2007 for launch of KSLV-l. This will make Korea be the 13th advanced country in space development having a launching site in the world. The "Space Center" will serve as the infrastructure for the development of space technology and related technology, and plan to launch a low earth orbit satellite in 2007. A second science satellite made in Korea will be launched from the space center by 2007. From 2010, the center will be operated on a commercial basis operating launch facilities for low-to mid-altitude orbit satellites. Since the 'Aircraft Industry Promotion Act' was replaced by the 'Aerospace Industry Development Promotion Acf of 1987, this Act had been amended seven times from 1991 year to 2004. Most of developed countries has been enacted the space law including the public or private items such as an (1)DSA, (2)Russia, (3)the United Kingdom, (4)Germany, (5)France, (6)Canada, (7)Japan, (8)Sweden, (9)Australia, (10)Brazil, (11)Norway, (12)South Africa, (13)Argentina, (14)Chile, (15)Ukrainian etc. As the new Space Exploration Promotion Act was passed by the resolution of the Korean Congress on May 3, 2005, so the Korean government has made the public proclamation the abovementioned Act on May 31, this year. This Act takes effect on December 1, 2005 after elapsing six months from the date of promulgation. The main contents of Space Exploration Promotion Act of 2005 is as the following (1)establishing a basic plan for promoting space exploration, (2)establishment and function of national space committee, (3)procedure and management of domestic and international registration of space objects, (4)licensing of launch by space launch vehicles, (5)lability for damages caused by space accidents and liability insurance, (6) organizing and composition of the space accident investigation committee, (7)Support of non-governmental space exploration project, (8)Requesting Support and Cooperation of Space Exploration, (9)Rescue of Astronauts and Restitution of Space Objects, etc.. In oder to carry out successfully the medium and long basic plan for promoting space exploration and to develope space industry in Korea, I think that it is necessary for us to enlarge and to reorganize the function and manpower of the Space Technology Development Division of the Ministry of Science & Technology and the Korea Aerospace Research Institute. Korea has been carrying out its space program step by step according to the National Space Program. Korea also will continually strengthen the exchange and cooperation with all the countries in the world under the principle of equality, friendship relations and mutual benefits. Together with all other peoples around the globe, Korea will make due contribution towards the peaceful utilization of space resources and promotion of human progress and prosperity.
