Abstract
A two-axis gyroscope in which precession may be effected by application of a DC current to the stationary precession windings. The rotor assembly has a pair of ring-shaped permanent magnets with their magnetic vectors aligned parallel with the gyro spin axis. This structure presents a magnetic field to the precession windings which does not change as the rotor assembly rotates. Thus the gyroscope may be precessed by application of a DC current to the precession windings. The precession windings are located along two orthogonal axes to allow precession of the gyro in two orthogonal directions.
