【摘要】 高级在轨系统AOS是空间数据系统咨询委员会CCSDS制定的关于星-星和星-地的数据管理系统。结合AOS系统协议和高分辨率遥感卫星在轨获取的各类载荷数据实际特点,设计了一种适应于高分辨率遥感卫星的空间数据处理系统。该系统把多种载荷产生的不同数据速率、不同字节大小、不同级别传输要求、不同延时要求的数据进行封装,形成统一的虚拟信道数据单元VCDU格式;并把各条虚拟信道上VCDU复接成连续的数据流经星地物理信道传输。仿真试验证明,该系统方案有效地解决了高分辨率遥感卫星多种载荷数据的组织、管理和传输问题,为后续的测绘和遥感处理奠定了可靠的数据基础。更多还原

【Abstract】 Advanced orbit system(AOS) is established to manage the data of satellite-satellite and satellite-ground by Consultative Committee for Space Data Systems(CCSDS).Based on the AOS agreement and the characteristics of the data obtained from the remote sensing satellite on orbit,a space data processing system has been designed to deal with the data with different speed,byte,transmission and time delay requirement to get the uniform virtual channel data unit(VCDU) format and to transmit the data in the form of successive data stream through satellite-ground physical channel.Simulation experiments have been carried out and the results show that the system is effective in organizing,managing and transmitting the remotely sensed data obtained from high resolution remote sensing satellites.A reliable data base for processing in the fields of geomatics and remote sensing has been provided.更多还原
