为了解决现有航天器载荷数据处理软件灵活度差、处理效率低的问题,设计了一种基于多级解包预处理策略以及并行处理调度算法的多格式载荷数据处理与管理平台.通过在某卫星的载荷试验数据处理与存储管理任务中的应用,验证了该平台设计的可行性和有效性.研究结果可为航天器多种格式的载荷数据并行处理与统一管理提供参考.

The mistake rate of in-orbit satellite diagnosis reasoning is a problem which is difficult to solve because of the complex technique frame of satellite and the bit errors of telemetry data. This paper proposed a diagnosis reasoning method based on credibility and degree of membership. And the credibility passing algorithm and the membership function prototype were given to support the diagnosis reasoning process. The argumentation indicates that the diagnosis reasoning mistake rate can be reduced with this method.

Based on Pushlet structure, a real-time monitoring and alarming system of browser/ server（B/S） mode for spacecraft in-orbit is proposed, which adopts the ＂publish/subscription＂ mechanism. Firstly, the client subscribes to a subject from the serve; secondly, the server ac- cepts and registers the subscription, and receives and interprets the real-time telemetry data from spacecraft. With the persistent HTTP link, the alarming information of telemetry parameters is published by the server and pushed to clients in time. Testing results show that the system has high real-time, efficiency and stability performances.
