  摘 要

  在大年夜范围停止初等级公路建立的同时,人们清晰地看法到勘测质量的短长直接影响着全部工程的质量。但遗憾的是,公路勘测设计依然没有解脱传统的勘测设计形式和方法,严重地制约了初等级公路树登时开展。若何有效地加快勘测速度,优化设计计划是设计人员面对的主要义务。

  随着计算机技巧、遥感技巧、丈量技巧及其相干技巧不时开展,GPS已不单单是个概念,它不时影响着传统的丈量方法。GPS线路控制末尾提出并逐渐成抱负。

  GPS作为新一代的卫星导航和定位系统,不只具有全球性、全天候、延续性、及时性的精细三维导航与定位才华,而且具有优胜的抗搅扰性和保密性。相干于经典丈量学说,GPS定位技巧具有不美观测点之间无需通视、定位精度高、不美观测时间短、供给三维坐标、操作轻便和全天候作业等主要特色。给公路测设事业注入了新的生机。

  Abstract

  In the large-scale proceeding high grade road that people clearly be aware that surveying quantity directly affect the quantity of whole engineering. But it is regret that the highway survey design still did not get away from the traditional surveying design mode and method, which seriously limit the development of high grade road. How to increase surveying speed and the design project is an important mission that design people must to face.

  Along with the high-speed development of computer, remote sensing, survey technique and correlative techniques, GPS already is not only a concept, it continuously affecting traditional survey method. The circuit with GPS controlled bringing up and come true.

  GPS is a new satellite navigates position system, it not only have global, all-weather, consecution, timely three dimension navigate with the fixed position ability, but also have the interference of good anti- with keep secret. Opposite to classic survey theory, GPS have no to need to see each other and have many advantages such as high position accuracy, short prognosticate time, offering three dimension, easy operation and all-weather working. Three advantages gave road surveying new vitality.
