Claims

[Scope of utility model registration request]

When a disturbance torque acts on the satellite and a certain plane of the satellite changes so that it no longer faces the earth, an attitude sensor detects the change in the attitude of the satellite and outputs an attitude signal proportional to the change in attitude. , a wheel driver that transmits a wheel drive signal proportional to a change in the attitude signal calyx to the flywheel; a detector that detects the rotation speed of the flywheel and transmits a rotation speed signal proportional to the rotation speed to a controller; A controller that outputs a magnetic coil control signal proportional to the rotational speed signal to the magnetic coil, and a control device that is caused by interfering with the earth's magnetism and the generated magnetism generated by the magnetic coil in proportion to the magnetic coil control signal. The satellite guinamics outputs the input torque as an input torque by subtracting the disturbance torque from the disturbance torque and transmits it to the flywheel. When generated in the station's logical operation circuit. In addition to an auxiliary controller that is mounted on the satellite and outputs an auxiliary magnetic coil control signal proportional to the Ouki erasure signal, the auxiliary magnetic coil control signal is taken out, and the auxiliary magnetic coil control signal is By outputting a proportional auxiliary generated magnetism with an auxiliary magnetic coil and having the auxiliary generated magnetism act on the earth's magnetism together with the generated magnetism, the attitude of the artificial satellite is adjusted so that a certain side of the artificial satellite always faces the earth. A magnetic attitude control device for an artificial satellite.
