GYROCOMPASS Russian patent published in 2014 - IPC G01C19/38 

FIELD: physics.

SUBSTANCE: gyrocompass has a housing 1 configured to rotate about its axis 2, which is mounted on a thrust bearing 3 and fixed in a vertical hollow shaft 4 of a worm gear 5, the input shaft 6 of which is linked to an actuating stepper motor 7. The housing 1 is linked to an external frame 8 which is configured to rock on the bearings 9, fixed in the housing 1. The external frame 8 is in turn linked to an internal frame 10, which is configured to rock in a perpendicular direction on the bearings 11, fixed in the external frame 8. On the internal frame 10 on the rocking axis, there is a first vertical post 12 on which a single-axis angular velocity metre is mounted, said metre being a fibre-optic gyroscope 13 with a closed feedback loop. On the housing 1 there is a second vertical post 14 on which there is a linear stepper motor 15, the drive screw 16 of which is connected through a shaft 17 with a nut 18 to the external frame 8. On the external frame 8 there is a third vertical post 9 on which there is a similar linear stepper motor 15, the drive screw 16 of which is connected through a shaft 17 with a nut 18 to the internal frame 10. A first accelerometer 20 is mounted on the outer part of the first post 12, which is rigidly connected to the internal frame 10. A second accelerometer 22 is mounted on a supporting arm 21 located below the outer frame 8, perpendicular to the first accelerometer 20. The whole structure is mounted on a plate 23.

EFFECT: high accuracy, reduced size of the measuring device designed for use in different engineering fields to measure and monitor angular velocity and angular position in inertial space.
