Strapdown inertial navigation system (SINS) is widely used in aerospace field. Complex motion, such as maneuver, will lead to additional errors in the SINS attitude algorithm. Accordingly an improved coning correction form is proposed to design efficient coning algorithms for SINS with rate gyro. This new correction form contains only one vector cross product, and is constructed by changing the traditional uncompressed angular rate-based form with a given definite relationship. The given relationship is derived, and is used for designing the improved coning algorithm. By analysis and simulation, it shows that the improved coning algorithm compared with the uncompressed rate-based coning algorithm has an equivalent maneuver accuracy which is significantly higher than that of the compressed rate-based algorithm, and a much lower algorithm computation load.
