  • Spacecraft control using residual dipole
    Patent number: 11124320
    Abstract: A method for desaturating reaction wheels of a spacecraft having a magnetic dipole is provided. The method includes orienting the spacecraft relative to an external magnetic field to apply a torque to the spacecraft via the magnetic dipole in a direction opposing momentum stored in the reaction wheels; and using the applied torque to unload at least some of the momentum stored in the reaction wheels. A corresponding spacecraft and non-transitory computer-readable medium are also provided.
    Type: Grant
    Filed: February 12, 2019
    Date of Patent: September 21, 2021
