摘　　要：随着空间技术的高速发展,任务运营管理系统日益庞大、复杂,管理成本也不断增加。针对这种情况,CCSDS提出了面向服务体系架构的任务运营管理系统参考模型,即MO服务参考模型。MO参考模型意在使任务运营系统成为由多个小型的、标准化的组件组装而成的系统。由于消息抽象层(Message Abstract Layer,MAL)的设计是MO参考模型的核心。文中以我国有效载荷运控系统的需求为出发点,同时依据MO MAL为参考,结合面向对象方法学,设计模式等理念,对MAL进行设计。With the rapid development of space technology,the mission operations system becomes increasingly large,complex,manage- ment costs are also increasing. In view of this situation, CCSDS proposed the mission operations system reference model for service-ori- ented architecture,MO service reference model. The MO reference model is intended to make mission operations system has become the system assembled by a series of small,staodardized components. Design of Message AbstrAction Layer （MAL） is core of the MO refer- ence model. Take needs of payload operation system as the starting point in this article, while based on the MO MAL reference,combined with object-oriented methodology, design patterns and so on, MAL is designed.
