In recent years, with the development of the micro-electronics technique, the price of GPS receiver have been greatly falling , and as a result of the United States closing SA to stop limiting the public position accuracy of GPS , the GPS positioning accuracy have improved greatly in public field. All this consumedly promote the development of GPS in public field, and especially in the vehicle navigation field , GPS shows its superiorly navigation performance.

近年来随着微电子技术的发展使得GPS接收机的价格大幅度下降，同时美国提前关闭SA停止对民间用户精度的限制使得GPS民用定位精度有了很大的提高，这大大促进了GPS在民用领域的发展，尤其是在车辆导航领域，GPS系统充分展示了它那优越的导航性能。

Firstly,subgoal choosing is optimized by using heuristic function according to the window's information,it is local environment's information,which is obtained by camera.Then navigation behavior is divided into GO TO TARGET behavior and OBSTACLE AVOIDANCE behavior,their behaviorial states and behaviorial modes dynamics models are established,and then one autonomous local path planning online is implemented using navigation behavior dynamics model in a single window.Connecting a series of local paths according to continuity,the robot accomplishes one global planning ultimately.

首先根据所获得的窗口信息，采用启发式函数进行局部子目标优化选择；然后将路径规划问题即导航行为分解为趋于目标行为和避障行为，并对这两种行为分别建立了行为状态和行为模式动力学模型；在此基础上，以窗口为单位，利用导航行为动力学模型进行在线自主路径规划；将一系列窗口中的规划轨迹按照连续性条件首尾相接，最终完成了一条全局规划任务。

The report has presented detailed research on concerned instances of integrated navigation and compared it with the system of the subsonic vehicle. The research has shown that the scheme composed of Changhe Ⅱ loran, Beidou satellite navigation system and GNSS for such subsonic vehicles is feasible and technically realizable.

本文对有关组合导航的实例进行了详细研究，与亚音速飞行器组合导航系统进行了比较研究，表明亚音速飞行器采用"长河二号"无线电导航系统、"北斗"卫星导航系统和全球卫星导航系统进行组合导航是切实可行的，在技术上是完全可以实现的。

With the fast development of the world trade and the technology of navigation, a vessel is becoming larger in size, higher in speed, more specialized in use and automatic in manoeuver; the seamen are much more multinational, and some sea areas are undergoing a heavier transportation pressure. All of these make the navigation environment worse and svessels manipulating ability lower, especially in those narrow channels.

但是，随着现代世界贸易和航海技术的飞速发展，船舶向大型化、高速化、专用化、自动化发展，船上配员向多国籍化发展，局部地区交通运输日益繁忙，尤其是在狭水道操纵安全，使得船舶航行环境变的恶劣和船舶运动性能也有所降低。

Through our analyzing the traditional navigation research methods of autonomous robot, the hybrid navigation method is put forward as masterstroke.

通过对国内外自主机器人导航方法的分析，提出了利用混合导航方法作为本文的研究的主线。

"Yes, now you can give yourself airs," she said, you have got what you wanted.

"对了，您现在高兴了，"她说道，这是您所期待的。

Then the LORD said to me: Rebel Israel is inwardly more just than traitorous Judah.
