Abstract

Abstract: With the development of satellite remote sensing technology, type and amount of remote sensing data are increasing rapidly. In order to meet the complex needs of multi-type data and high rate remote sensing data transmission, a top-level design of the data transmission stream was presented, and both remote sensing/data transmission system data interface and data transmission frame format were defined, then a classified calculation of transmission rate required for remote sensing data transmission was put forward to provide a prerequisite for the design of a fixed down-link data transmission rate. Then a data transmission stream design was proposed based on the virtual channel dynamic scheduling with subgroup priority to ensure that the transmission of different types of remote sensing data meet the requirements of different applications, in which the high-speed remote sensing data was processed with small cache capacity requirements while the low speed one was done to satisfy the real-time transmission demand. Dynamic simulation results demonstrate the correctness of the proposed scheme. The suggested approaches have a reference for design of the follow-up new generation remote sensing satellite data transmission system.
