基于ECSS标准的航天器姿轨控系统内1553B总线数据协议设计

摘要： 国内外航天器姿轨控系统广泛应用基于1553B内总线的体系结构.针对国内航天器姿轨控系统内部1553B总线数据协议不统一带来的可集成性、可扩展性和通用性差的问题，本文设计了基于ECSS标准的姿轨控系统内1553B数据总线协议，从姿轨控系统内部总线数据业务需求分析出发，提出了四层结构的数据协议体系结构，重点介绍了在应用支持层和链路服务层应用ECSS标准的总线协议设计，并说明了协议的应用情况.应用该国际通用的标准协议，有助于实现国内航天器姿轨控系统内1553B总线数据协议的标准化，进而提升姿轨控系统体系结构的可集成性、可扩展性、以及星载设备(含软件)的通用化.

Design of 1553B Data Bus Protocol Based on ECSS for Spacecraft Attitude and Orbit Control System

Abstract： Configuration based on internal 1553B bus is widely usede in attitude and orbit control system of international spacecraft. Aiming at the problems of poor integration,poor extensibility and poor generality caused by the non uniform bus data protocol of attitude and orbit control system for Chinese spacecraft,internal 1553B Bus data protocol based on ECSS is designed.A four layer data protocol architecture is proposed based on the analysis of the data sevice requirments of the internal bus of attitude and orbit control system.The design of the bus protocol based on ECSS in application support layer and link sevice layeris is mainly introduced and the application of the protocol is explained.The application of this international standard protocol is helpful to standardize the 1553B data protocol in attitude and orbit control system for Chinese spacecraft.The integration and extensibility of the attitude and orbit control system and the generalization of on board equipment(including software) are improved.
