The figure of the relative kinematical track of the formation flying will change which is in an ellipse because of the disturbing force from which the satellitessuffer. A simple way of control is developed that saves the fuel, that is, in Hill orbital coordinates, through themeasurement of x-axis and z-axis, the control of the small jet engine will eliminate the phase excursion of the center of the ellipse and the non-coplanarity of the orbit of satellites.
