The Architecture of Pico-Satellite Nodes in Satellite Formation Network Based on Reconfigurable Distributed Computing

The development situation of communication system of small satellites in formation in China and aboard is first introduced. With the development of small satellites at present and the needs of small satellites for space flying mission, the fundamental technologies of hardware structure supporting reconfigurable computing based on FPGA and the distributed computing technology are analyzed in this paper. The application of these two technologies in formation-flying pico-satellites communication is demonstrated, and it is verified through an experiment of distributed compressing images that the distribution technology can be implemented in such a reconfigurable hardware structure. The combination of these two technologies can make good use of software and hardware sources of pico-satellite. A design scheme of pico-satellite based on these two technologies is presented at last.
