摘要
GPS静态定位技术用于公路控制测量 ,观测时间短 ,测量精度高。但在定线放样中其应用受到局限 ,GPS实时动态定位技术克服了这一局限性。论述了 GPS实时动态动位技术的定位原理及其在公路定线中的应用方法 ,并结合工程实例对其应用效果进行精度分析 ,提出工程应用中应注意解决的问题。
GPS static positioning technique was widely used in highway control survey because of its fast speeding and high accuracy in survey, but it was limited in location survey, and RTK(real time kinematics) technique was beyond the shortcoming. This paper discussed the positionning principle and application methods of GPS RTK technique in highway location survey. Combined with the engineering examples, the positionning accuracy of GPS RTK and the solution of main problems in application were put forward.
