导航

GPS has been widely adapted as the main positioning tool nowadays after development for more than 20 years with a new generation updating. The applications of areas and prospects dimension of GPS have exceeded its original purpose. It has become a very important technical method and solution way in almost every field of transportation, communication, metrology, aerologic and so on.

全球定位系统GPS作为新一代的卫星导航定位系统，经过二十多年的发展，已发展成为一种被广泛采用的系统，它的应用领域和应用前景已远远超出了该系统设计者当初的设想，目前，它在航空、航天、军事、交通、运输、源勘探、通信、气象等几乎所有的领域中，都被作为一项非常重要的技术手段和方法，用来进行导航、定时、定位、地球物理参数测定和大气物理参数测定等。

In an INS ,the stability of the output of the accelerometer is affinitive with the temperature,and the tempera- ture stability directly determines whether INS can work immediately and stably or not.

在惯性导航系统工作过程中。加速度计输出的稳定性与温度有很大的关系，温度的稳定性直接影响着惯性导航系统能否快速启动并稳定工作。

After learning SEO, the first my station is to make station of special subject of a novel, also be actually temporarily actuation, registered a domain name, immediately analytic, made a single page immediately, seemed to see a love in those days of navigation navigation optimize case, want to imitate the way of grave old, want babyishly to use a single page to accomplish that novel the first go.

学了SEO后，我的第一个站是做一个小说专题站，其实也是一时冲动，注册了一个域名，马上解析，马上做了一个单页面上去，那时好像看了一个爱吧导航导航的优化案例，想模仿丘老大的做法，幼稚的想用一个单页面把那个小说做到第一去。

Based on the different features of HModulated gyro monitor inertial navigation system,electric navigation chart and bathometer,this paper presents an integrated HMGMINS/ENC/BM navigation system.

This paper mainly narrates the design and study of vehicle navigation function. And it studies the realization and idea of several key techniques in the system, includes map circumrotation, navigation position calculation etc.

随后论文提出了车载导航系统中基本功能的设计思想，并研究了几种关键技术的实现方法，其中包括：地图的旋转，导航推位，内存绘图等。

So, the study in this dissertation focuses on some key points in theuncertainty treatment of mobile robot localization as follows: Combined with the multiple proprioceptive and exteroceptive sensors ofmobile robot MORCS-1, aimed at the drift error of fiber optic gyro as theproprioceptive sensor, the neural network using genetic algorithm as optimaltool is proposed to accomplish the modeling and calibration for temperaturedrift of fiber optic gyro, which can reduce the drift error to the standard outputat constant temperature; and aimed at the noisy disturbance of ranging datafrom the exteroceptive sensor laser scanner, a dynamic adaptive filter isintroduced through the analysis of neighboring ranging data in time and spatialcorrelation to realize the real-time and dynamic filter, which can validly filter the noisy disturbance to meet the requirement of the accurately real-timeobstacle detection in mobile robot navigation.

总结全文，在移动机器人定位的不确定性处理研究中，提出了一些具有一定创新性的方法：结合自行研制的移动机器人MORCS-1系统的多种内外部定位传感器，针对内部本体感受传感器光纤陀螺仪的漂移误差，提出采用基于遗传算法优化的神经网络来对光纤陀螺仪的温漂建模及校准，能够将其温漂变化控制在恒温条件下标准测试输出附近；针对外部环境感知传感器激光雷达测距数据中包含的噪声干扰，考虑移动机器人导航中激光雷达测距数据的时空关联性，提出采用动态自适应滤波技术进行预处理，从而可以有效滤除噪声干扰满足导航中障碍实时精确检测的要求。

Etc. In the third part of this paper, we chooses some Webs with typical form of network information organization appropriate and analyzes these Webs from three angles. The three angles are four parts of Information Architecture"s sustainable effectiveness in practice of findability、the user"s cognitive psychology and Personal Navigation、the users social psychology and Computer Supported Cooperative Work and Social Navigation.
