卫星信息的服务过程包含从作战单元发出任务请求直至服务响应的整个环路,Meta图能够全过程描述链路从获取卫星下传信息到最终生成卫星应用产品与服务的信息状态转化规律。提出了基于Meta图的卫星应用信息链建模方法,利用基于关联矩阵的最大Meta路迭代算法求解卫星应用信息链服务路径。拓展了解决卫星应用分析、建模、设计、评价问题的思路,为卫星应用的全过程服务提供决策支持。
The service process of satellite information includes the entire loop from the mission unit issuing the mission request to the service response. The Meta graph can describe the whole process of link state transition from acquiring satellite downlink messages to generating satellite application products and services in the whole process. A meta-graph-based satellite application information chain modeling method is proposed, which uses the largest Meta-way iterative algorithm based on association matrix to solve the satellite service information chain service path. The ideas of solving satellite application analysis, modeling, design and evaluation problems have been expanded to provide decision support for the whole process of satellite applications.
