The coupling between spacecraft attitude and orbit movement in an integrated model based on the spiral theory was analyzed. The method parameters analysis method was used, which changed the coupling parameters successively, to get the curves and the laws of coupling terms. The validity of theoretical analysis was proved. To verify the coupling impact on the control effect, the control law was designed. The result shows that the coupling seriously affects the attitude and the orbit of relative motion, and the attitude influences the orbit motion a lot, and can converge easily, while the orbit has little effect on the attitude.

To unify the description of relative position and attitude of the formation flying satellites, a boating algorithm based on dual quaternion was proposed. Using the dual-quaternion method, the kinematics model of formation flying satellites was established and its physical meanings were analyzed. This algorithm combined the solutions for relative position and attitude calculating. Simulation results indicate that the algorithm can effectively describe the relative position and attitude of formation flying satellites in a scientific and rational way. [ABSTRACT FROM AUTHOR]
