摘　　要：利用三个陀螺仪和一个里程计提出一种新型GPS/DR组合导航系统。首先推导了这种组合导航系统的状态方程,然后给出了松组合方式的滤波方程。最后用实测算例对这种新型组合导航系统进行了验证,结果表明,相比于SINS系统、传统的DR系统,这种DR系统在车载系统应用中具有更好的优势;而且这种组合导航系统能够很好地提高单一导航系统的导航精度。In this paper,a new GPS/DR integrated navigation system consisting of three gyros and one odometer is presen-ted. The state equation of this integrated navigation system is deduced. The filtering equation of the loose integration mode of this new GPS/DR system is given. The new GPS/DR integrated navigation system was verified by actual calculation. The result shows that the new DR system has more superior than SINS system and traditional DR system,and this new GPS/DR integrated navigation system can improve the navigation accuracy the simplex navigation system.
