导航技术

Timing, modern communication, navigation and position, and computer auto-control all depend on precision time scale and accurate time synchronization.

精密计时、现代通信、导航定位和计算机自动控制等都离不开精密时间尺度和时间频率测量技术。

Sytematic introduction of GPS theory and its three sub-systems, with focus on GPS's role in transportation which includes road engineer, auto navigation, traffic supervision and etc, has been presented in this paper. Thanks to its ability to provide continuous high-precision 3-dimensional coordinate all day round, technical parameter of 3-dimensional speed and time information, GPS has been widely used in public transport system in recent 2 years.

本文系统介绍了GPS的原理和其三大子系统，着重介绍了GPS系统在交通运输中的应用，包括在道路工程、汽车导航和交通管理中的应用以及其他应用， GPS全球队定位系统在公交系统中的应用，在最近两年得到了迅速的推广，这主要依赖于GPS系统可以向全球任何全天候地连续提供高精度的三维坐标、三维速度和时间信息等技术参数。

Purchase of Retired HMAS Melbourne: The aircraft carrier research programme was boosted when a Chinese ship breaker purchased the retired 15,000t aircraft carrier HMAS Melbourne from Australia.

向澳大利亚购买其退役的HMAS&墨尔本&号航母：该计划最终成行。（1985年2月）当中国在澳大利亚购买了其已退役的15000吨级HMAS&墨尔本&号轻型航母（&墨尔本&号原为英国海军&尊贵&号轻型航母，舷号R77）后，中国的造船工程师获得了一个研究航母设计建造思路、流程的绝好机会，中国的航母研究被大大推进了（作为西方阵营的一员，澳大利亚是不会轻易让中国得到航母技术的，在交船之前，澳方已经把关键的蒸汽弹射器、导航雷达等设备拆除。

in modern container terminal operations, the global positioning systemis applied to navigating the rubber-tired gantry craneto eliminate operation mistake, and the gps can be integrated into a container terminal operation system such as cosmos.

在现代化的集装箱码头堆场作业中使用gps卫星定位技术为轮胎吊导航定位，以减少消除移箱错误，提高作业效率。gps定位系统又是可以被有机地集成到现有的集装箱码头堆场作业系统如cosmos之中，形成定位加作业的二合一的新系统。

PBiz is based on the super-proximity routing algorithm proposed in this dissertation, and it also extends the P2P routing algorithm to support exact-match lookup and fuzzy search. Using XML technology, PBiz provides the user with effective navigating service, which enhances the advantage of eCommerce.

与此同时，PBiz并扩展了现有的结构化对等网络路由算法，扩展后的路由算法能同时支持精确查找与模糊查找，同时，结合XML技术，提供给用户实时有效的信息导航服务，进一步提高了电子商务的优势。

The success of modern UAVs such as the Predator is not due to a single technological breakthrough, but to the combination of innovations in several areas—faster computers, fly-by-wire controls, satellite navigation, miniaturisation of sensors and fast data-transmission—into a workable and affordable whole.

现代无人机的成功并不是单一科技成果的突破而带来的，而是几种不同科技领域的创新的综合——更快捷的计算机、远程驾驶控制、卫星导航、传感器的微型化以及快速的数据传输技术——遮掩就形成了一个有利工作并能承受的整体。
