FOG north finder effect

Fiber optic gyro north finder is a kind of independent instructions found bearing high precision inertial instruments. It can not enter the latitude values, carrier and true north direction angle which is given.

Use of fiber optic gyroscope measured rate of the earth from the Angle of value and the measured gyroscope and accelerometer horizontal plane Angle, through computer calculating carrier of baseline and the true north direction Angle, carrier to get the value of the azimuth is placed on the baseline of the accelerometer to measure found north finder attitude Angle.

Fiber optic gyro north finder found the fiber optic gyro is used by fiber optic ring, semiconductor laser, Y waveguide devices, they are solid state devices, there are no moving parts, the equipment can impact resistance, resistance to vibration. Other types of the optical fiber gyro can’t do it.
