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.
