Abstract

According to the success of the Nuri Space Launch Vehicle (KSLV-II) and the development goal of the next generation space launch vehicle (KSLV-III), it is expected that the domestic geostationary satellite capability will be increased from (1 to 3.7) ton. Also, it is predicted that substantial ability of about 1 ton can be provided for the space exploration of the Moon, Mars, asteroids, etc. The Goheung space launch site is optimized for sun-synchronous small satellites, and due to the essential precondition that the launch trajectory does not impinge another country's sovereign airspace, it is not satisfactory as a geostationary satellite launching site. Its latitude also requires more energy to shape the rotating orbital plane from the initial injection status. This results in a decreasing factor of economic feasibility, including the operating complexity. Therefore, in parallel with the development of a next generation space launch vehicle, the practical process for acquisition of oversea land or sea space launch site near the Earth's equator and research for the optimization of orbiting methods of geostationary satellite injection must be continued.

누리호의 성공과 차세대 우주발사체의 개발 목표를 통하여 국내 정지궤도위성 발사능력은 1톤에서 3.7톤으로 향상될 것으로 기대되며 화성, 소행성 등의 우주탐사에도 1톤 이상의 실질적인 능력을 제공해 줄 수 있을 것으로 예측된다. 고흥 우주발사장은 태양 동기궤도 소형위성에 최적화되어 있으며 타국의 영공을 침범하지 않아야 된다는 필수적인 전제조건으로 인하여 정지궤도위성 발사장으로는 다소 부족한 면이 존재한다. 초기 궤도 투입상태로부터 궤도면 회전을 위한 에너지의 증가가 필수적이며 운용 측면에서의 복잡성과 함께 경제성의 감소요인이 된다. 그러므로 차세대 우주발사체의 개발과 병행하여 지구 적도부근의 해외 지상발사장 또는 해상발사지점의 획득과 최적화된 정지궤도위성 투입에 관한 궤도 구성에 관한 연구가 계속되어야 한다.
