GPS在公路測(cè)量中的應(yīng)用

GPS測(cè)量具有高精度、高效率的優(yōu)點(diǎn), 在控制測(cè)量領(lǐng)域得到了廣泛的應(yīng)用. 隨著GPS接
收機(jī)性能和數(shù)據(jù)處理技術(shù)逐漸完善, GPS應(yīng)用領(lǐng)域也不斷拓寬, 實(shí)時(shí)GPS測(cè)量在公路工程中
將得到更廣泛的應(yīng)用。本文簡(jiǎn)述了GPS 測(cè)量技術(shù)的發(fā)展?fàn)顟B(tài), 特點(diǎn)以及利用其進(jìn)行公路選
線、中線測(cè)量、縱橫斷面測(cè)量的方法.結(jié)合GPS 測(cè)量技術(shù)在公路測(cè)量實(shí)際中的應(yīng)用,重點(diǎn)介紹了靜態(tài)GPS 測(cè)量技術(shù)和RTK技術(shù)在公路測(cè)量中的應(yīng)用,最后對(duì)GPS 測(cè)量作出了總結(jié)及體會(huì)。

Abstract: GPS measure has the virtue of high precision and high efficiency, it has been applied widely at control measure domain. With GPS receiver and data processing technique’s gradually consummation, GPS appliance area is been widen ceaselessly, real time GPS measure will be applied widely at road project. The assay depicts simply GPS measure technique’s development state, point and the way of calzada fix line、midline measure and transect measure. With GPS measure technique’s appliance at road measure fact, it produces mainly static state GPS measure technique and RTK technique’s appliance at road measure, at the end it summarizes and give the taste at GPS measure.
Keywords: GPS,RTK technique, road measure
