Method of improving the north seeking result

A vehicle is disclosed which carries a vehicle orientation system FOA together with a north-seeking system operating independently therefrom for orienting its equipment. According to the invention, the two systems are bidirectionally linked together and results determined in the individual systems are transmitted to the respectively other system so as to increase its accuracy and for other corrections.

Vehicle having an on-board navigation system

A gyrocompass including a first gimbal, a gyro motor mounted in the first gimbal and including a gyro rotor mounted to rotate about a horizontally alignable spin axis, a pendulous body in which the first gimbal is mounted to be rotatable about a vertically alignable axis of rotation, a housing in which the body is rotatably suspended, a verticality device associated with the body for allowing the body to assume an orientation in the housing in which the axis of rotation is vertical, and a follow-up device including a pickup mounted for sensing the angular position, about the axis of rotation, of the gimbal relative to the body and a drive connected for rotating the body relative to the housing about the axis of rotation in dependence on the position sensed by the pickup. The drive can be constituted by a stepping motor constructed to rotate in highly uniform steps and simultaneously serving to provide an indication of the angular position of the body relative to the housing about the axis of rotation. Alternatively, the drive can be constituted by a stepping motor constructed to rotate in highly uniform steps, the follow-up device can include a restraining circuit and a torquer connected between the pickup and the first gimbal for restraining the first gimbal at a defined angular position, about the axis of rotation, relative to the body, the restraining circuit providing a signal representative of the angular velocity of the first gimbal about the axis of rotation, and the gyrocompass can further include a unit for determining the direction to true north from signals representative of the angular velocity.

Gyrocompass

A magnetic bearing assembly for a rotor, including at least two actively regulated magnetic bearings for stabilizing the rotor in directions oriented substantially perpendicularly to one another and to the axis of rotation. The magnetic bearings define a bearing plane oriented perpendicularly to the axis. The rotor has a center of gravity situated at an axial distance from the bearing plane whereby tilting motions of the rotor about tilt-axes perpendicular to the axis of rotation can be sensed and counteracted.
