Since in the 1950s of the 20th century, continuous development of space technology, spacecraft under application are different, the development of the formation of communications, meteorological, navigation, resources and environment, and military surveillance series of scientific research and high performance, highly integrated development. A number of small - sized spacecraft through cooperative work to realize the function of a large - scale space vehicle, will be more economical, flexibility, reliability, and you can implement more powerful function of advantages. therefore, the spacecraft formation flying in recent years has become one of the hot spots of space research. On the relative motion of two aircraft in the air of abstraction modeling, first of all from the most basic concepts of formation flying, advantages and development at home and abroad in the fields such as understanding, which involves abstract model simulation, so it is necessary to understand the basic knowledge of simulation. secondly, on the kinematics of modeling involved in the process, dynamics and the attitude description method of knowledge addressed, according to the reference literature, to some extend deduction. In several common attitude description, clear advantages and disadvantages of the various methods and their constraints. finally, the establishm

ent of a model is relative motion between the two aircraft, export six - degree - of - freedom equations of motion of universal. Simulation of Simulink in Matlab software module for simulation platform, set the relative motion of scenario, after completing simulation analysis to Simulation results, determine the applicability and use of model equation constraints.
