摘　　要：针对未来航天器中多元化的用户业务对星载设备中数据的采集、存储、修改等处理以更灵活、高效的方式实现的需求,研究分析了CCSDS制定的存储器访问业务的特点、作用及基本的工作原理。通过分析可知,应用CCSDS存储器访问业务可以有效解决当前星载综合电子系统的局限,满足未来航天器数据处理的更高要求。文章提出了其在航天器综合电子系统中的应用场景、可行性、方法和工作模式,对存储器访问业务在未来综合电子系统中应用的优势进行了初步探索。Due to the multiple user services of future spacecraft, more flexible and efficient approach is needed for on-board data processing including data collection, data storage and data modification. This paper analyses the features, functions and basic working principles of CCSDS Subnetwork Memory Access Service. The analysis shows that CCSDS Subnetwork Memory Access Service can effectively solve the limitation of current on-board system, and satisfy the high demand of future spacecraft data manipulation. The paper proposes the application scenarios, feasibility and working modes, then makes a preliminary probe for the application advantages of CCSDS Subnetwork Memory Access Service in the future spacecraft avionics system.
