摘要
针对北京三号B卫星高速数据和在轨智能处理需求,设计数据处理与传输分系统。提出标准化、智能化、模块化的设计思路,开发路由、高速存储、通用处理、电源等标准单元的智能处理器,实现数传产品对数据流向灵活可控、功能高集成、在轨可重构的需求。配置高性能FPGA和智能计算芯片,系统实时图像压缩、处理速度达到20 Gbit/s。采用云检测、辐射校正、目标识别、目标提取、目标定位等星上数据智能处理技术,可为在轨图像智能处理建立指标体系提供参考。数据处理与传输分系统通过在轨验证,测试结果满足用户需求。
A data processing and transmission subsystem is introduced for the requirements of high-speed data flow and in-orbit intelligent processing of the BJ-3B satellite.The ideas of standardization,intellectualzation and modularization are put forward.The intelligent processor with standard units of routing,high-speed storage,universal processing and power supply are developed.The requirements of adaptive data flow,high function integration and in-orbit reconfiguration of data transmission product are solved.The subsystem is equipped with high-performance FPGA and intelligent computing chip.The real-time image compression and processing speed of subsystem can reach 20Gbit/s.By adopting cloud detection,radiometric correction,target detection,radiometric correction,target recognition,target extraction,target positioning and so on,the subsystem can provide a reference for the establishment of an index system for in-orbit image intelligent processing.The data processing and transmission subsystem has passed the in-orbit verification,and the test results are acceptable for users.
