【Abstract】 Aiming at the problem of residual torque and residual angular momentum generated by active loads on a spacecraft, a method for measuring and calibrating the residual torque and residual angular momentum of a spacecraft on the ground based on a three-axis air float table is presented, and the system composition and work are given. The principle and the design scheme of the integrated control system above and below the stage, analyze the identification method of the rotary inertia of the air floating platform, demonstrate the measurement algorithm of the residual moment and residual angular momentum, and give the test steps. Finally, the effectiveness of the proposed method is verified by mathematical simulation. The results show that the residual moment identification accuracy is better than 5%.更多还原
