초록

KASS(Korea Augmentation Satellite System)는 국토교통부에서 2014년부터 개발 중인 한국형 위성항법보강시스템이다. KASS는 항공기 안전에 영향을 미칠수 있는 항공용 시스템이기 때문에 KASS의 각 소프트웨어는 안전성 분석을 통해 할당된 DO-178B의 소프트웨어 레벨에 따라 개발이 수행된다. KASS의 하위시스템인 통합운영국의 경우 일부 소프트웨어를 제외하고는 DO-178B 레벨E를 할당 받았으며 DO-178B 레벨E 소프트웨어의 경우 제품 보증을 위해 ECSS-Q-ST-80C 카테고리 D를 준수하여 개발하도록 하고 있다. 본 논문에서는 ECSS-Q-ST-80C를 만족하기 위해 ECSS-E-ST-40C, ECSS-Q-HB-80-04A를 분석하여 KASS 통합운영국 소프트웨어의 제품 보증을 위한 소프트웨어 생명 주기 별 활동 및 소프트웨어 품질 모델, 메트릭을 제안한다.

Korea augmentation satellite system (KASS) is the Korean satellite based augmentation system (SBAS) developed by ministry of land, infrastructure, and transport (MOLIT) since 2014. Since KASS is the safety critical system that can affect to the safety of airplane, the software of KASS is developed according to the DO178B software level induced from safety analysis. In case of KASS control station (KCS), most of the software of KCS get assigned software level E in DO178B. In that case, ECSS-Q-ST-80C category D is assigned as a software product assurance standard. In this paper, the software related standard ECSS-E-ST-40C, ECSS-Q-HB-80-04A are analyzed to satisfy ECSS-Q-ST-80C and as a result the software product assurance activities regarding software life cycle and the software quality model, metric is proposed for the product assurance of the KCS software.
