A new impulsive feedback control law is developed for the elliptical relative motion based on relative orbit elements (ROE). The control of the in-plane and out-of-plane relative motions can be completely decoupled using the new method, which are suitable for both elliptical and circular reference orbits. The ROE-based control method needs four thrusts to achieve the elliptical relative motion control. Two different impulsive in-plane control methods are proposed. Different typical orbit maneuvers, including formation establishment, reconfiguration, long-distance maneuver and formation keeping are simulated to demonstrate the performance of the proposed ROE-based control laws.
