无卫导条件下多舰船联合导航方法研究

Combined Navigation Method for Multi-warship Without Satellite Navigation

为解决多舰船在无卫星导航条件下面临的导航保障能力下降的问题,提出采用多舰联合导航的方法,以安装惯导系统的舰船为母舰,仅安装平台罗经的舰船为子舰,建立多舰联合导航体系,母舰通过测算获得子舰相关信息,并将其发送给子舰,以提高子舰的导航信息的可靠性和有效性,进而保障舰船编队的导航信息准确和连续。通过实例进行验证,建立多舰联合导航体系并进行导航信息有效性仿真实验,实验结果表明:采用编队联合导航方法后,单舰的定位误差有明显的下降,为保障舰船编队航行提供理论参考。

To solve the problem of the navigation supportability of the vessel formation without satellite navigation,a combined navigation method for multi-warship is proposed.The ship with inertial navigation system is a motheship,and the ship only established platform compass is a subship,and the combined navigation system was established by a motheship and a subship.The mothership measures the related information of a subship and sends it to the subship to improve the reliability and effectiveness of the subship's navigation information,ensuring the accuracy and continuity of the navigation information.Finally,the combined navigation system simulation experiment is also carried out and the result shows that the position accuracy of single subship has been improved obviously with the joint navigation method,which provides a theoretical reference for ensuring ship formation navigation.
