Compact FOG-Based True-North Finder for Navigation System
The Fiber Optic Gyroscope (FOG) North Finder is a state-of-the-art navigation instrument designed for rapid and autonomous determination of true north. Utilizing advanced fiber optic gyroscope technology, it accurately measures the Earth's rotation angular velocity, resolves the rotational signals, and calculates the precise angle between the gyroscope's main axis and true north, providing reliable azimuth information for a wide range of platforms and carriers.
This electromechanical integrated system combines a fiber optic gyroscope, high-precision accelerometer, mechanical rotation control unit, and an embedded computer, ensuring fast alignment, stable performance, and accurate north-seeking capability even in GPS-denied or magnetic interference environments.
Ideal for applications in military navigation, surveying and mapping, mobile platforms, industrial positioning, and oilfield drilling orientation, the FOG north finder is the ultimate solution for precise, reliable, and autonomous azimuth determination.
