Abstract

Low cost launch vehicle for next-generation is underway in advanced space countries such as the United States, Europe, Japan and China. This paper surveys the latest technological trends in avionics system, including ground management system. In the case of on-board equipment, to make short the development period and reduce the cost, the equipment is standardized and modularized for each functions to flexibly respond to changes in system requirements. In addition, a network is applied to all inter-equipment interfaces and a powerful self-diagnostic function is included in the equipment to realize automation/simplification of the interface with the ground system, and it is confirmed that an efficient launcher system is realized.

미국, 유럽, 일본, 중국 등 우주 선진국에서 효율성 및 저비용을 목표로 차세대 상업용 발사체를 위한 연구가 활발하게 진행되고 있다. 본 논문은 지상운용시스템을 포함한 발사체 에비오닉스 시스템에 대한 최근 기술동향들을 조사하고 소개하는 것이다. 탑재장치의 경우 개발 기간을 단축하고 비용을 절감하기 위해 기능별로 장치를 표준화하고 시스템 요구조건 변경에 유연하게 대응하도록 모듈화를 진행한다. 또한 모든 장치간 인터페이스에 통신망을 적용하고 강력한 자가진단 기능을 탑재장치에 포함시킴으로써 지상시스템과의 인터페이스에 자동화·단순화를 실현하여 효율적인 발사체계시스템을 구축하고 있음을 확인한다.
