Engineered for defense, surveying, and autonomous navigation, the Fiber Optic Gyroscope North Finder provides rapid, high-accuracy true-north determination. The system derives the Earth’s rotation angular rate using an advanced FOG sensor, ensuring excellent azimuth accuracy and stability.
With a compact structure (115 × 90 × 110 mm) integrating a gyroscope, accelerometer, rotation control unit, and embedded computer, it offers ≤3 min alignment and ≤0.3° accuracy.
Its rugged design withstands -40 °C to +70 °C, operates on DC 12–24 V, and delivers data through RS-422. Suitable for geodesy, mapping, and tactical navigation, this north finder is optimized for precision performance in demanding field conditions.
