摘　　要：要实现水下精确导航,采用单一导航方法,其精度、可靠性无法满足需要.将多种导航技术适当融合,可以取长补短提高导航精度.以捷联惯性导航系统作为组合导航系统的主导航设备,GPS导航、多普勒导航等为辅助导航设备,利用联邦Ka lman滤波技术对水下组合导航系统进行信息融合,充分融合多导航传感器信息,提高远程自主水下航行器的导航精度.It is difficult to realize precise underwater navigation by using single navigation method. The integration of a variety of navigation technologies can improve the preciseness of navigation . This paper presents a combination of navigation aids which takes SINS as the main navigation equipment, GPS and DVL as assistant navigation. Fusing the information from multiple sensors by Federal Kalman filter technology can provide precise navigation for underwater vehicle.
