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.

A two-axis gyroscope comprising: a current directing assembly for producing controllable magnetic fields; a source means for providing plural currents to said current directing assembly; a single rotor assembly of unitary structure rotatable about a spin axis, said rotor assembly comprising: first means for providing a first magnetic field characterized by a magnetic vector oriented parallel to said spin axis such that said field remains constant with respect to said current directing assembly as said rotor assembly rotates; second means, fixed for rotation with said first means, for providing a plurality of second magnetic fields, each characterized by a magnetic vector orthogonal to said spin axis such that the magnetic field produced by said second means varies with respect to said current directing assembly as said rotor assembly rotates; third means, fixed for rotation with said first means, for providing a third magnetic field characterized by a magnetic vector parallel to said spin axis such that said field remains constant with respect to said current directing assembly as said rotor assembly rotates; and said second means is located axially between said first and third means, with its central axis coincident with said spin axis; said rotor assembly being mounted proximate said current directing assembly, whereby interaction of some of said controllable magnetic fields with said second magnetic fields causes said rotor assembly to rotate about the spin axis and the interaction of others of said controllable magnetic fields with said first magnetic field and said third magnetic field causes said rotor assembly to precess.
