Hall thrusters are commonly used in the propulsion system of geosynchronous earth orbit satellites. Since the small output thrust, the hall thruster can effectively improve the orbit position keeping accuracy. For geosynchronous earth orbit satellites with large angle maneuver requirements, the fuel will be consumed in a large amount in a short time during the execution of the mission, resulting in the satellite center of mass deviation, causing the thrust vector of the propeller to deviate from the center of mass, thus generating interference torque and causing the flywheel to saturate. To ensure the overall stability of the satellite, it is necessary to continuously consume fuel to eliminate the influence of interference torque and unload the flywheel. Based on the above background, this paper presents an estimation method for thruster burnup of satellite attitude control systems under the disturbance torque of the electric thruster. First, the saturation of the flywheel is judged according to the analytical formula of flywheel angular momentum. Second, the theoretical fuel consumption of jet unloading is calculated according to the value of flywheel angular momentum in the saturated state. Finally, three feasible electric thruster layout schemes are simulated and analyzed. The simulation results show that the proposed method can quickly estimate the attitude control burnup caused by the disturbance force of the electric thruster., and the layout of two thrusters is better than that of four thrusters.
