FOG North Finder with 0.3°Accuracy True Finder with RS422 Interface
The Fiber Optic Gyroscope North Finder provides precise true-north orientation for navigation, mapping, and weapon guidance systems. This all-in-one device automatically detects the Earth's rotational rate and computes accurate azimuth and attitude data within 3 minutes.
The system integrates a high-accuracy FOG, accelerometer, motorized turntable, and embedded computer. With ≤0.3° north-seeking accuracy and ≤0.05° horizontal accuracy, it delivers stable, repeatable performance for UAVs, armored vehicles, and surveying equipment.
