Inertial navigation system based on atomic interference gyroscope and optical gyroscope combined sensing

The invention relates to an inertial navigation system based on atomic interference gyroscope and optical gyroscope combined sensing. The inertial navigation system comprises an atomic interference gyroscope, an optical gyroscope, a carrier and a navigation and electrical control cabinet, the atomic interference gyroscope and the optical gyroscope are arranged on the carrier and are fixedly connected with each other, and sensitive axes of the atomic interference gyroscope and the optical gyroscope are in the same direction; the navigation and electrical control cabinet tracks the zero offset drift of the optical gyroscope and corrects the zero offset of the optical gyroscope by controlling the rotating speed of the carrier and utilizing the output correlation of the atomic interference gyroscope and the optical gyroscope; and then navigation calculation information is obtained based on the output of the optical gyroscope after zero offset correction, high-precision and high-stability absolute rotating speed m
