野外自主车陆地组合导航系统研究

INTEGRATED LAND NAVIGATION SYSTEM OF AUTOMOBILES

在分析了各种导航系统特点的基础上，本文提出了一种新的组合导航系统─—由陆地惯性导航系统和全球定位系统构成的陆地组合导航系统。在建立组合导航系统数学模型的基础上详细讨论了组合滤波器设计，系统校正方式等设计问题。分析了系统非线性和斜坡等对导航系统性能的影响。

This paper proposes a new navigation system for automobiles the integrated land navigation sys-tem consisting of the land inertial navigation system and Global Positioning System(GPS). The principle ofthe integrated land navigation system is described and some important aspects such as integrated filters,openor closed loop feedback mode are discussed.The simulation result shows that the integrated land navigationsystem proposed in this paper exhibits the nice performance.
