<p>A gyroscope unit for a vehicle has a vertically supported navigation gyroscope with a north-seeking gyroscope enabling correction of the navigation gyroscope indication when the vehicle is at rest. The navigation gyroscope is rotated about its vertical axis (7) by resetting devices engaging the horizontally mounted frame. The north reference is transferred to the navigation gyroscope without gimbal errors even when the vehicle has an inclined attitude. This is achieved economically and without addition time. Measurement instruments (10) determine the deviation from 90 degrees of the angle between the planes of both gyroscope frames (2,4). The reset devices are controlled to correct the navigation gyroscope indication using the north-seeking gyroscope and according to the measured angular deviation. The deviation is nulled and the new navigation gyroscope direction determined by the north-seeking gyroscope.</p> |
