Aiming at the non-stationary character of signal noise of fiber optic gyro (FOG) in the stabilized platform, the signal model of FOG and some methods of noise reduction are analyzed and discussed.
A larger high-frequency noise in the output signal of fiber optic gyro lowers the calculation accuracy of fiber optic gyro attitude system.
