Abstract：In the navigation and positioning of ships,speed updating is an important part,and the sculling error compensation is needed in the speed calculation,so the high-precision sculling error compensation algorithm is a hotspot of navigation and posi-tioning research.Under the condition of classical paddling motion,the error optimization coefficients are derived in detail,and an improved paddling error compensation algorithm based on the velocity increment and angle increment of the previous period is pro-posed.Compared with the traditional algorithm,the accuracy of the optimization algorithm is improved,and it has certain practical value.
