  • Free-falling body verification device for drag-free spacecraft
    Patent number: 10202211
    Abstract: A free-falling body verification device for a drag-free spacecraft comprises a spacecraft simulation device (1), used for carrying out free-falling body motion on the ground; an inertial sensor or accelerometer (2), used for measuring the residual disturbance acceleration of the spacecraft simulation device (1); an attitude sensor (3), used for measuring attitude parameters of the spacecraft simulation device (1); a drag-free controller (4), used for processing the residual disturbance acceleration and the attitude parameters so as to obtain a feedback control signal; and a propeller (5), used for generating thrust action applied on the spacecraft simulation device (1) under the control of the feedback control signal, so as to enable the spacecraft simulation device (1) to overcome the residual disturbance of the external environment and maintain the attitude.
