The core principle of a gyrocompass, including the CMZ 900, is the use of a fast-spinning rotor that is suspended with virtually no friction. This rotor is influenced by gravity and the Earth's rotation, causing its axis to align with the true north, irrespective of the ship's magnetic field. Consequently, the device provides an accurate and stable heading reference, essential for navigation and steering control systems.
