Design and implementation of joint processing architecture based on multiplexing frame and payload data package

针对复杂遥感卫星多类海量数据处理效率低下等问题,设计了一种基于数传CCSDS复接帧和多路载荷包联合处理的信息处理架构。该架构融合数传前端系统与载荷前端系统,对数据作二维统筹处理,是多路载荷数据快速恢复的技术基础。基于此架构开发的载荷信息处理系统,经实际应用表明能大幅提高卫星多路数据处理效率,使数据恢复达到高实时性;同时具有通用性,满足多类复杂遥感卫星研制和测试的需要。

A processing architecture based on CCSDS multiplexing frame and payload data package is designed in this paper to solve the low processing efficiency in mass data process system of advanced remote sensing satellites. Two processing dimensions of this architecture,demulitiplexing system and payload data process system,have been joined together in the whole data process sequence,which is the foundation of the rapid payload data recovery. The data process system developed based on this architecture can substantially enhance the process efficiency of satellite-multi-payload data in real use as to meet the demands of high instantaneity of data recovery. The data processing system proves it works well and has good generality in practical applications of satellite development.
