| Zusammenfassung: | The invention belongs to the field of inertial navigation, and discloses a mechanically dithered laser gyroscope sensing axis dynamic offset error parameter estimating and compensating method. The method comprises the following steps: 1, establishing the kinetic equation of the dynamic offset deformation angle of a mechanically dithered laser gyroscope sensing axis; 2, simplifying the kinetic equation of the dynamic offset deformation angle of the mechanically dithered laser gyroscope sensing axis; 3, establishing the dynamic offset error model of the mechanically dithered laser gyroscope sensing axis; 4, establishing the parameter of the dynamic offset error model of the mechanically dithered laser gyroscope sensing axis; and 5, compensating the dynamic offset error of the mechanically dithered laser gyroscope sensing axis to realize compensation of the dynamic offset error of the mechanically dithered laser gyroscope sensing axis under a vibrating condition. The method solves the problem of influences of th |
