Claims

[Scope of utility model registration request]

When a disturbance torque acts on an artificial satellite and the certain side of the artificial satellite changes so that it no longer faces the earth,
An attitude sensor that detects changes in the satellite's attitude and outputs an attitude signal proportional to the change in attitude, and a rotating wheel driver that transmits a rotating wheel drive signal proportional to the change in attitude signal to the magnetically supported rotating wheel. a detector that detects the rotational speed of the magnetically levitation supported rotary wheel and transmits a rotational speed signal proportional to the rotational speed to the controller; and a detector that outputs a magnetic coil control signal proportional to the rotational speed signal to the magnetic coil. The control torque generated by the controller and the interference between the generated magnetism generated by the magnetic coil and the earth's magnetism in proportion to the magnetic coil control signal,
satellite dynamics that is output as an input torque by subtracting it from the disturbance torque and transmitted to the magnetic levitation supported rotating wheel, while at the ground station the rotational speed of the magnetic levitation supported rotating wheel reaches saturation. It has a logic operation circuit that sends a magnetic control command to the satellite in response only to the rotation speed signal corresponding to the time, and the logic operation circuit sends the magnetic command to an auxiliary controller on the satellite, and the auxiliary controller outputs a magnetic coil control signal proportional to the magnetic control command, inputs the auxiliary magnetic coil control signal to an auxiliary magnetic coil also provided on the satellite to generate auxiliary generated magnetism, and generates auxiliary generated magnetism. An artificial satellite characterized in that, in addition to the generated magnetism, the attitude of the artificial satellite is controlled so that one bottom surface of the artificial satellite always faces the earth by acting on the earth's magnetism together with the generated magnetism. Magnetic attitude control device.
