基于CCSDS-SOIS的航天器数据管理系统体系架构的探讨
Discussion on onboard data management system architecture based on CCSDS-SOIS
摘要
Abstract
The consultative committee for space data systems(CCSDS)established space onboard interface services (SOIS)area and working group in 1 9 9 9,and developed a series of recommended standards for onboard interfaces. According to european space agency(ESA),national aeronautics and space administration(NASA)and chinese acade-my of space technology(CAST)experience,they practiced and built their own architecture for onboard data manage-ment system,named space avionics open interface architecture(SAVOIR),core Flight Executive/core Flight Software(cFE/cFS)and CAST flight software respectively.The study contents of these architectures mainly focus on layered architecture,services,protocols,data organization and tool-chains development.They have many same characteristics and differences.For instance that they have similar layered frames,but different services divided and protocols configured.The reason of this situation is mainly coming from different background and culture of organizations and countries.One of these architectures'goals is to allow components reuse in a system development. The characteristics of reuse include layering,modularization,interface standardization,and modeling.Modeling plays a key role in these features.Based on CCSDS SOIS,electronic data sheet(EDS)and management information base (MIB)concepts have been used to describe different models of components(applications,services and devices)and systems.The relationship between EDS and MIB,their contents and formats,are discussed.Finally,some trends of architecture developing methods are predicted.First,the EDS technology will be the one of core study contents of SOIS,including its method,language,tool-chains development and management method.Second,MIB will be the base for missions and system design due to its modeling feature.And the last is that we should use SOIS architecture and develop our own spacecraft onboard data management architecture according to the special background and environment of our country,such as organization style,culture,rules of space engineering,infrastructure,working habits,and etc..关键词
