Abstract :
It is very difficulty to obtain continuous time solution from relative motion equation between two spacecrafts with ellipse trajectory. Therefore, we have to assume that the target spacecraft motions along a circular or nigh-circular trajectory, but we not have to assume the external force to be zero. This paper will give an accurate analysis solution of the relative motion equation of rendezvous and docking without any assumption of external force, and generalize analysis solution of the Hill equations from zero external force case to any case.
