| Abstract: | In this paper,a deep research is made on the algorithm of high precision strapdown inertial navigation system (SINS) under highly dynamic situation and a new threeloop algorithm for SINS is proposed. This algorithm includes the attitude coning compensation and the velocity sculling as well as the rotation compensation. The mathematical models of updating the earth fixed coordinate frame,the navigation coordinate frame and the body coordinate frame are given in this paper,and the mathematical models of the above three effects are also given.The computer simulation for this algorithm is taken and the result is shown in the end. |
