Abstract :
In the self aim of the inertial navigation system, utilizing the original aim of two positions, the output signal of the fiber gyro is filter with wavelet analysis, the original direction of the cosine matrix is confirmed, and the inertial element is demarcated. It is more suited for the cluster-sampling system of the fiber gyro, when it is no method to compensate the excursion with the modeling method. It may be seen from the simulation examination that the analysis of wavelet and the method of two positions which are used in the cluster-sampling system of the fiber gyro acquire the content outcome. To the cluster-sampling system of the fiber gyro, the analyzing method making use of the wavelet may effectively remove the noise and distill the useful signal of the original aim, this method is simple and the result removing the noise is ideal
