  • Publication number: 20150168440
    Abstract: The present invention relates to a method of measuring the rotating speed of a sphere for controlling the posture of a satellite. The method includes: an accelerometer installing operation in which a pair of accelerometers is installed at each accelerometer coordinate axis, the accelerometers being located in the sphere; an accelerometer coordinate axis alignment operation in which the accelerometer coordinate axes are aligned to allow the accelerometer coordinate axes to be in line with system coordinate axes, respectively; an acceleration measuring operation in which a current is applied to an electromagnet to rotate the sphere and sequentially measure the acceleration; an acceleration calculating operation in which only the acceleration generated by the rotation of the sphere is calculated; and a rotating speed calculating operation in which the rotating speed of the sphere with respect to each coordinate axis is calculated using the acceleration.

  • Patent number: 8346410
    Abstract: Provided are an attitude control system and method of a spacecraft of an artificial satellite that may enhance a maneuverability and a controllability by simultaneously applying a reaction wheel and a thruster among drive units used to maneuver an attitude of the spacecraft of the artificial satellite. The attitude control system may include: a thruster-based attitude controller which control firing time of thrusters mounted on the spacecraft; and a reaction wheel-based attitude controller controlling driving of a reaction wheel mounted on the spacecraft. The spacecraft may include a plurality of reaction wheels. When a defect occurs in the spacecraft due to a partial malfunction of the reaction wheels, an attitude maneuverability of the spacecraft may be corrected by simultaneously applying the thruster-based attitude controller and the reaction wheel-based attitude controller.

  • Publication number: 20090159753
    Abstract: A reaction wheel momentum management method using a null space vector is provided. In accordance with this method, when any one of at least four reaction wheels used for triaxial control is made unavailable or degraded, a degraded wheel is used as long as possible for improving the mobility of the behavior of a satellite. The method provides momentum management for an N-number of reaction wheels W1, W2, . . .
