Abstract: The method of hovering at any selected position to spacecraft target was studied.For the present open-loop method was sensitive to external disturbance and initial error,a close-loop hovering method was proposed based on the Hill equation.The simulation was performed and the method was validated.It shows that the fuel consumption of two control methods are approximate but the performance of the close-loop control is better,which can realize hovering at any selected position to spacecraft target in spite of the initial velocity error.
