Title: Free gyroscope device
Inventor: MATSUDA YOSHIHISA
IPC: G01C19/02
Filed: 1984-04-19
Abstract: PURPOSE:To offset the torque disturbance, which is yielded by the oscillating angle of the rotor of a gyroscope, by applying the torque whose amount is the same as that of the torque disturbance and direction is opposite to the torque disturbance, to the rotor of the gyroscope. CONSTITUTION:An angle detector 11 detects an oscillating angle thetay around the (y) axis. Torque Td, whose amount is the same as that of torque disturbance, which is generated with respect to said angle and direction is opposite to the torque disturbance, is generated by a rotor control device 12 and applied to a gyroscope rotor 1. Thus the torque disturbance Td is offset. In this way, the torque disturbance due to the oscillating angle thetay around the (y) axis 3 of the spin axis of the gyroscope rotor can be offset. The defects of decrease in space stability and accuracy due to the torque disturbance caused by the oscillation of the gyroscope rotor in a conventional free gyroscope can be improved.
