With the upgrading of navigation speed and accuracy requirements, optical sensor has already become inertial navigation system component of a new generation. Fiber optic gyro with small size, light weight, low-vibration, easy maintenance, good performance and good price ratio become the first choice components high precision inertial navigation system. But fiber optic gyro operation still has lots noise interference. Among FOG operation the biggest impact on the accuracy of the drift error. Analyses of dynamical drift error of fiber optical gyro with kalman filter in the thesis. Experimental results show that kalman filter can lower allan variance of system effectively and improve accuracy of fiber optical gyro.
