摘　　要：为了提高舰船在机动转弯情况下的定位精度和舰船定位的稳定性、可靠性,进行了滤波模型和滤波定位算法的研究,在此基础上分析了当前滤波模型和滤波定位算法中存在的一些问题,提出了基于船舶操控模型的滤波模型和改进后的UKF滤波算法,给出了滤波系统的方案。通过实验证明,滤波系统的方案不仅能够有效的提高舰船在机动转弯情况下的定位精度,还能够作为测量ASF修正数据有效方法,对定位算法的研究有重大的参考价值和较大的现实意义。For improving the positioning accuracy and reliability of ship on the condition of turning,the issue of current filtering model and filtering algorithm are analyzed, the filtering model and improving filtering algorithm are researched. A filtering model is given which ba- ses on ship control model and improved UKF filtering algorithm Designing a scheme for filtering system, the experimental result indicated that the scheme for filtering system algorithm has a good effect on positioning accuracy on the condition of ship turning, but also offering a method for measuring ASF data.
