RS422 Output North Seeker Fiber Optic Gyroscope Sensor for Tunnel Mining
The NF701 Fiber Optic North Finder delivers fast, accurate true-north orientation for navigation and targeting systems. Using a high-performance fiber optic gyroscope to detect the Earth's rotation, it computes azimuth and attitude angles automatically within 3 minutes.
Compact (115 * 90 * 110 mm) and lightweight (≤2 kg), the system integrates a FOG, accelerometer, rotation control device, and embedded computing unit. With north-seeking accuracy up to 0.3° (1σ) and power consumption of only 15 W, it's ideal for UAVs, land vehicles, and shipborne systems requiring magnetic-free north finding.
