摘　　要：舰船采用内水平阻尼工作状态导航时,因受到舰船机动的影响,系统会产生较大的动态误差,影响系统的导航精度。为提高系统的导航性能,在研究舰船机动对惯导系统影响的基础上,提出引入外速度补偿阻尼惯导系统的方法,以减小系统的动态误差。经仿真结果表明,该方法能有效克服舰船机动的影响,提高惯导系统的精度。When the inertial navigation of the ship works under the condition of interior level damp, the system will be influenced by the ship maneuver,which will make the system＇s dynamic error great and influence the system＇s navigation precision. In order to improve the navigation property of the system, this paper proposed the method of incoming the speed compensates the damping inertial navigation to reduce the system＇s dynamic error on the bias of the research to the inertial navigation system influenced by ship maneuver. The simulation result shows the method proposed by this paper can overcome the influence of ship maneuver effectively and improves the system＇s navigation precision.
