摘要
介绍了全球定位系统实时动态测量(GPSRTK)高程的理论方法和数学模型,基于工程实例和实验数据研究了起算点的空间分布、起算点数量和拟合方法对高程拟合精度的影响,提出了提高水准拟合精度的有效措施。
The application of GPS RTK basic principles and mathematic model in channel control survey are introduced.At the same time,based on an example of project and experiment data,this paper shows what extent height simulation precision is affected by spatial distribution ,quantity of original points and simulation methods.Moreover,this paper proposes some effective means which can enhance simulation precision.
