 Hello, In China, we call norh seeking gyro North Finder.

It is widely used by Inertial Navigation.

 You can make a simple zero axis gyroscope into a basic north finding gyroscope by placing the gyro at the bottom of a sealable glass jar and suspending the jar by a fine thread so that the axis of the gyro is horizontal to the surface of the earth and the force of gravity is always acting upon the gyro to attempt to keep the axis horizontal. You want to seal the gyro in a container so the air current it creates does not act like a fan to disturb the gyro. The gyro will then oscillate back and forth around the torsion free (neutral) position of your thread and will travel further towards north or south. You will see there is more travel away from the torsion free location when it seeks a pole. You then experiment by rotating the thread at the top support of the thread in the direction the gyro wants to move towards so that eventually there is an equal amount of oscillation each side of the torsion free position. The torsion free position (in the middle of the oscillation) is now pointing towards a pole. Commercial devices dampen the oscillation by computer and adjust the torsion free position either manually using a fine rectangular shaped wire or automatically. For a basic device you are going to have to power down the gyro move the torsion free location and make a note of it and power up again and observe the oscillation and keep repeating this cycle till eventually the oscillation is exactly either side of the torsion free position.
