| 摘 要： | 通过实验对实时动态RTK技术定位精度进行了研究，并提出了结合投影已知点和利用载体速度、路段起始点坐标两种确定载体位置的方法进行最优估计的方法，其结果作为实时动态RTK的最终定位位置。公式推导表明，最优估计的可靠性要高于单独使用一种方法的可靠性。

| Abstract: | This paper studies the accuracy of real-time kinematic RTK through an experiment,and gives the best estimation by combining two methods of matching vehicle position: One is to project the known points and the other is to employ velocity of the vehicle and the coordinate of starting and terminal points.The result is regarded as the vehicle location located by real-time kinematic RTK.It is verified by formula that the stability of the best estimation is higher than by the single method. |

| Keywords: | real-time kinematical RTK positioning accuracy the best estimation |
