Based on the foundation of anatomizing the structure of robot, taking full advantage of parallel move performance of the double triangle boom of the rock-drilling robot ac-cording to the condition of the diversification of the boomend location brought by the change of each joint, integrating the knowledge of robot kinematics, an expert system is established to adopt the personate means, that is" the first toorientate the end, then to orientate the location "to realize the speediness orientation.

作者在分析凿岩机器人钻臂结构的基础上，利用钻臂的双三角支架的空间平移性能，根据各关节变化所引起的钻臂端部位姿的变化，综合机器人学中运动学知识，建立一个专家系统，采用拟人化的方案———"先定点，再定位姿"，解决凿岩臂的快速定位问题，以实现描述各关节位置的变量的快速逆运算。

At last, the analysis of uboot in MPC813, which is the main controller of the system is presented, especially the remap and relocation in stage 1 in the framework of PowerPC.

文章的最后针对了OLT端的主控芯片MPC8313的Uboot进行了分析，结合PowerPC的架构着重研究了Uboot中stage1的两次重要重定位过程，第一个重定位是在系统要加入对SDRAM映射时发生的，对MPC8313内存空间的重新设定。

GPS surveying based on GPS reference station network can improve the reliability and veracity, eliminate and weaken the infection of atmosphere error and orbit error which is relative to time and space in the observation of GPS surveying, which makes the rapid static pointing and RTK dynamic pointing of medium and long distance into reality, and has virtues of acquirable WGS84 coordinate directly.

采用基于GPS基准网的GPS测量可以提高GPS测量的可靠性和准确性，可以消除和减小GPS测量观测值中与时间和空间相关的大气误差和轨道误差的影响，使中、长距离快速静态定位和RTK动态定位成为现实，还具有可直接得到WGS84Z坐标等优点。

Passive locating methods have the merits of far distance,concealable receiving and low probability to be detected,compared to active locating methods.

Prospect future, super voice the wave spread the feeling machine conduct and actions a kind of new count for much and useful tool and will have very big development space in everyone's noodles, it wears the dynasty more high to position the direction development of the high accuracy to develop increasingly by satisfy of social need is basic such as the development trend of the sonar is:Develop to have higher fixed position accuracy of passive measure to be apart from sonar to carry out the demand of whole concealment attacks by satisfying weapon in water;Continue to develop the submarine of the adoption low frequency line table examination to drag the line array sonar, carry out super long range of passive probe into and identify;Develop the submarine sonar of the more suitable for neritic work, resolve the target in the neritic water to identify a problem especially;Lower a submarine strongly from the bad voice, the work environment of the improvement submarine sonar.

展望未来，超声波传感器作为一种新型的非常重要有用的工具在各方面都将有很大的发展空间，它将朝着更加高定位高精度的方向发展，以满足日益发展的社会需求，如声纳的发展趋势基本为：研制具有更高定位精度的被动测距声纳，以满足水中武器实施全隐蔽攻击的需要；继续发展采用低频线谱检测的潜艇拖曳线列阵声纳，实现超远程的被动探测和识别；研制更适合于浅海工作的潜艇声纳，特别是解决浅海水中目标识别问题；大力降低潜艇自噪声，改善潜艇声纳的工作环境。

The location sensing system is an underlying component for location-aware computing in Smart Space, which not only demands the location sensing system to locate multiple objects with desirable precision, but also superimposes the requirements, such as directional characteristic and portability etc, on it.

定位系统是智能空间位置感知计算的基础部件，它不仅要能较精确定位多目标，而且在方向性、可携带性等方面也要满足要求。

First,a landmark model is designed to give position information;second,color segmentation,invariance of cross-ratio and the self-adaptive window are used to detect the artificial landmark,so the position information is got;finally,in order to locate the mobile robot accurately,the binocular stereo vision is used by combining with the position information of artificial landmark.

首先设计了一种可扩展的彩色人工路标，并给出路标的编码方法；然后利用色彩空间变换，直线交比不变性以及自适应窗口实现路标检测与识别；最后在分析双目立体视觉模型的基础上建立起基于路标的双目立体视觉定位模型，实现移动机器人的准确定位。

Also, it presents the 0/D charging system for taxies based on mobile localization information technology. In the new charging system, the trip charge is determined by the information of origin and the destination.
