Abstract: The problems of control method and fuel consumption in random relative stationkeeping in close range to a space debris were investigated. Based on CW equations, control model was established in closerange stationkeeping on a random relative fixed point. The statefeedback controller was designed. The controllability and thrust requirement was studied. Results show that two orthogonal constant forces relating to position of the fixed point, and three orthogonal forces along three axes of the orbital frame to counteract to the perturbation, are required in closerange stationkeeping. Then the basic configuration scheme of satellite subsystem for stationkeeping control was proposed and discussed. The analytical models for fuel consumption and fuelconsumption rate were established. Finally, the minimum fuel consumption model was analyzed in closerange hovering with safedistance demand and relativeorientation demand being satisfied.
