The invention relates to a multi-satellite compatible satellite remote sensing ground receiving and processing system and method thereof. In the prior art, different processing systems are adopted for satellites having less load and high rate and satellites having much load and low rate; and hardware switching is necessary to be carried out when different satellite models are processed. According to the multi-satellite compatible satellite remote sensing ground receiving and processing system and method thereof disclosed by the invention, ground receiving and processing for different satellite models are realized by dynamic configuration of an FPGA loading file; aggregation from multiple SRIOx1 interfaces to SRIOx4 interfaces is realized through an FPGA; conversion from an SRIO interface to a 10-gigabit network TCP / IP interface is realized through a POWERPC; the problem that the existing ground single processing system cannot satisfy use of multiple satellites can be solved; therefore, the system is simple to operate; and simultaneously, the cost is reduced.
Description
technical field [0001] The invention relates to the technical field of satellite communication, in particular to a multi-satellite compatible satellite remote sensing ground receiving and processing system and a method thereof. Background technique [0002] With the development of remote sensing satellite technology and the improvement of application requirements, the spatial resolution and time resolution of remote sensing satellites have been greatly improved, and the original image data acquired is very huge. There are more and more satellite types and load modes, and the working modes are ever-changing. Ground baseband data processing equipment for inverse processing of satellite payload data processing must meet the high-performance data processing requirements of various satellites. In the prior art, different processing systems are used for satellites with less payload and high speed and satellites with more payload and low speed, or multiple systems need to be used i...
