10.2.2 Architecture Framework for Spacecraft Computer Control Safety System

Abstract

AbstractWe have a strong demand to design computer control safety system because crew stats to stay the international space station continuously, but there is no design framework for spacecraft computer control safety system. In this paper, we propose the architecture framework for spacecraft computer control safety system to guide a safety systems engineer to design computer controlled safety system. This framework is based on the general safety design process and NASA's computer safety requirements. The architecture framework can be proposed in accordance with the coming new IEEE1471 standard. This architecture framework can cover all design processes which are mandatory to be conducted to design system safety architecture. From this result, we suppose that this architecture framework reaches at least mandatory level.
