Fiber Optic Gyrocompass (FOG) – Marine Precision
A Fiber Optic Gyrocompass (FOG) is a state-of-the-art maritime navigation tool that detects true north and heading using light and the Sagnac effect, rather than spinning rotors. Unlike mechanical systems, FOGs employ coils of optical fibers to sense angular velocity. This leads to superior performance in rough seas, fast vessel maneuvers, or magnetic interference zones. FOG systems are found in naval, commercial, and offshore vessels where real-time, precise heading is critical. They require minimal maintenance, deliver quick start-up, and offer high reliability—ensuring enhanced navigational safety and performance.
