N2 - This paper proposes a spacecraft dynamics full-physical simulator based on air bearing technology, which can effectively simulate the micro-damping dynamic environment of spacecraft in outer space. This paper gives the kinematics model and dynamic equations of the simulator, and analyzes the similarity of the attitude dynamics between the simulator and the real spacecraft. Referring to the real on-orbit spacecraft, the simulator selects the reaction flywheel and the gas injection system as the actuators, designs a control switching algorithm, and uses data fusion technology to switch the mode of the attitude measurement system. Finally, an attitude control simulation test is carried out. The test results verify the correctness and feasibility of the simulator. Using the full- physical simulator proposed in this paper, we not only can carry out spacecraft dynamics experiments on the ground, but also can verify various algorithms, which has important engineering application value.
