The Fiber Optic Gyroscope (FOG) North Finder is a precision instrument used to determine true north quickly and accurately without relying on GPS or magnetic fields. It measures the Earth’s rotation angular velocity through high-precision fiber optic gyroscopes and calculates azimuth information for navigation and orientation applications. Suitable for land vehicles, ships, and defense systems requiring reliable north-seeking performance.
