Fast North Finding FOG North Finder
Detailed Images
1.1 Product Usage
Fiber optic gyroscope (FOG) north finder is mainly used to determine the true north direction rapidly and independently. It uses the two basic characteristics of gyroscope, i.e. precession and axis-fixing, to realize the autonomous North finder. The angular rate of the earth's rotation is obtained by high precision FOG tracking. The angular rate signal of the earth's rotation is calculated, and the angle between the main axis of the gyro and the true north direction of the earth is calculated to provide azimuth information for the carrier.
