Abstract The method of space circular formation order optimized design was given by using the reformed heredity algorithm based on three micro-satellites flying in formation on a same orbit and by performing the three dimensional solid mapping for terra.The method could ensure steady formation order for a long time under various perturbations.The calculated formula of the inter-satellite links of LEO formation-flying satellite was derived according to the special requirements of inter-satellite links of the formation-flying micro-satellite,and the transmitting power was also confirmed through the simulation.The inter-satellite direct spread spectrum communication system was set up,and the simulation demonstration was performed.The input waveform and the output waveform match well.The simulation results provide a good theoretical basis for the formation flight and for the inter-satellite communication demonstration experiment.
