摘要：
At present the Fiber Optic Gyroscope (FOG) is usually used in INS (Inertial Navigation System) as an inertial component, its error is the important factor that effect navigation precision of system, however, the precision of FOG is lower that it is necessary to analyze the performance and give the error parameters to raise the precision. In this paper, the test data of FOG are analyzed, and using the AR (2) model to estimate the parameter of state equation, and receive the statistic characteristic of noise from observation information. And then, we use Kalman filter technique to wipe off the noise from the gathered data. At last, the simulation result of the fiber optic gyroscope testing data is given. And Matlab is used in programming the simulation program, and the testing curve is given.
