Fiber Optic Gyro North Finder with 0.01° Azimuth Accuracy 3-Minute Alignment and GPS-Independent Operation

Fiber Optic Gyro North Finder Module FOG-NF1-09

The FOG-NF1-09 is a self-contained north finding module that achieves 0.01° azimuth accuracy with a rapid 3 minute alignment time. Using precision FOG and quartz accelerometer technology, this system autonomously determines true north without GPS, magnetic compass, or any external reference.

Key Features

• High Azimuth Accuracy: 0.01° (1 sigma) accuracy from 0° to 60° latitude, maintaining performance in both northern and southern hemispheres.
• Fast 3-Minute Alignment: Four-position indexing scheme completes the north-seeking process in 3 minutes typical, with optional extended averaging for higher precision.
• GPS-Independent: Fully autonomous operation using Earth rotation sensing — no RF emissions, no signal vulnerability, and no magnetic interference.
• Wide Latitude Coverage: Operates from 0° to 75° latitude (North and South) with automatic latitude compensation.
• IP65 Enclosure: Weather-resistant construction for field deployment in adverse conditions.
• Field Proven Algorithm: Proprietary filtering and error modeling reduce the effects of vibration, temperature drift, and seismic noise.
