摘要
针对遥感载荷下行数据流设计不一致问题,提出了一种遥感载荷地面数据处理平台的设计思路和实现方法,对遥感载荷数据流模型描述和任务指令建立等关键技术进行了分析。该方法构建的系统通过配置能够适应不同遥感载荷数据流结构,具备通用性。系统主要处理节点采用刀片服务器完成运算,各个处理节点之间松耦合,实现了插件式部署,可供多节点复杂结构处理系统设计时参考。
Payload data flow scheme may largely vary with the mission of the remote-sensing sat- ellite. How to design and implement a processing platform adjustable to different payload data flow schemes is introduced in this paper. How to create the playload data flow model and con- struct a set of task commands is analyzed. The main processing nodes of the platform are implemented with blade servers, and all the processing nodes are loosely coupled and can be deployed easily. The general idea of the paper can be used to construct a complex and multiplex system with many processing nodes.
