摘　　要：传统的航天器信息交互机制逐渐难以适应具有更高复杂性和动态性的航天器信息网络和应用需求。文章针对航天器内部及之间信息交换关系日益复杂的发展趋势,将空间数据系统咨询委员会(CCSDS)建议的异步消息业务的主要机制和属性与空间信息系统网络化特点相结合开展分析研究工作,研究异步消息业务应用于星内星间一体化网络中的特点和优势,给出基于异步消息业务解决上层应用需求和网络结构动态变化典型问题的方案和示例,阐述了异步消息业务对高动态星间网络的支持效果。研究结果表明,异步消息业务可以解决星内星间一体化网络复杂性和动态性两方面问题。最后对异步消息业务在航天器上的工程应用与实现提出了建议。Traditional onboard information exchange manner can not adapt the new information networks and application requirements with more complexity and dynamics on spacecraft. For the more and complex information exchange in the future inner and interspaceeraft network,this paper analyses the attributes, functions and mechanisms of CCSDS asynchronous message service with the characteristics of the space information system and network. The characteristics and advantages of the asynchronous message service are analyzed, in view of use in the inner and interspaceeraft network. How to deal with the changes from both upper application and the structure of network is provided based on the asynchronous message service, and how can the asynchronous message service support the dynamic interspacecraft network is also given. The research work indicates the asynchronous message service can solve the problems both of the complexity and dynamics of the networks. Some advices on engineering actualization for spacecraft are also suggested.
