Problems solved by technology
[0003] During the 13th Five-Year Plan period, there is a large gap in the ground processing requirements of high-resolution satellite data transmission data in my country. The code rate of some digital transmission products can reach 4 channels × 1.5gbps. At present, modulators with a single-channel code rate of up to 2.5gbps have been developed, and the ground processing at the corresponding rate The technology cannot meet the existing data transmission rate, and the ground receiving and processing system of ultra-high-speed satellite remote sensing data has become an urgent problem to be solved in the process of international aerospace development
[0004] At present, no description or report of similar related technologies has been found, and similar materials at home and abroad have not been collected yet.

The invention provides a multi-channel satellite remote sensing data processing and storing system. A data transmission server host is provided with a PCI-E data processing board interface, gigabit Ethernet ports, 10-gigabit optical fiber ports, and an iSCSI data optical fiber transmission interface. A PCI-E data processing board card is embedded into the data transmission server host through the PCI-E data processing board interface. The data transmission server host and the PCI-E data processing board card jointly complete satellite remote sensing data processing. A disk array is connected with the data transmission server host through the iSCSI data optical fiber transmission interface, and is used to store satellite remote sensing data. A 10-gigabit network switch is connected with the data transmission server host through one of the 10-gigabit optical fiber ports. The data transmission server host requests a data transmission baseband for satellite remote sensing data communication through four 10-gigabit optical fiber ports. The invention further provides a test method implemented by the system. The system and the method of the invention effectively meet the demand of ultrahigh-speed satellite remote sensing data storing and processing.
Description
technical field [0001] The present invention relates to satellite ground ultra-high-speed remote sensing data storage and processing system, specifically, what relates to is an ultra-high-speed multi-channel satellite remote sensing data processing and ISCSI storage system and testing method based on 10gbps optical fiber transmission of Ethernet, which is applied to satellite Ground testing of ultra-high-speed remote sensing data storage and processing capabilities. Background technique [0002] With the development of my country's satellite industry in recent years, the amount of domestic remote sensing satellite data has increased sharply, and the data transmission code rate has continued to increase. At present, the known satellite high-speed remote sensing data test system can only support real-time data storage at a code rate of 4 channels*450Mbps. deal with. [0003] During the 13th Five-Year Plan period, there is a large gap in the ground processing requirements of hi...
