Abstract: Aiming at the requirement of point accuracy in highway measurement，a GPS data process method is introduced based on a carrier phase linear composing and GAMIT software．The result shows that thiS method could get more accuracy for GPS positioning．The base-line accuracy comes to 2 em when the base-line in several kilometers，which meets the demand of highway control measurement．
Key words: high accuracy, GPS measurement, GAMIT software, data process
摘要： 针对目前高等级公路测量对点位精度要求的提高，提出了对不同载波的GPS相位观测量进行线性组合后，再 利用GAMIT软件数据进行处理的方法，试验结果表明，此方法可以在公路控制测量中获得较高GPS定位精度，即在 几公里的距离范围，基线精度可达到2 em，满足公路控制测量的要求．
