Abstract: The development of the high downlink rate of the new type remote sensing satellites, increases the difficulty of the real-time acquiring of the high speed and large quantity remote sensing data of the ground receiving system. The paper introduces the design of a high speed remote sensing satellite data acquiring card based on the PCI bus technology, and the realization of the remote sensing data record system, made up of the sever computer, remote sensing satellite data acquiring cards and Raid, which has the characters of high performance, low cost and simple structure and supports the input rate up to 400Mbps.
