Simulation research of direct spread spectrum communication system for micro-satellite formation-flying constellation

The content of this paper is a subtask of Nation-863 High Tech Item. Two micro-satellites perform formation-flying and inter-satellites communication demonstration test in a circular orbit. The optimizing design method of space circular formation order based on mend heredity algorithmic is given; the method can ensure formation order steadily for a long time under various absorb impetus. The inter-satellite direct spread spectrum communication system based on IEEE 802.11 wireless protocol is put up, and the simulation demonstration is performed
