摘要(Abstract)：

针对多路径误差的空间分布特征,该文提出采用克里金插值法构建多路径误差的空间插值模型。通过采用ArcGIS中克里金插值工具构建的多路径误差的空间插值模型,较好地展现出多路径误差与测站位置、反射源距离等因素的空间分布特征。实验结果表明:对比泛克里金插值法、普通克里金插值法、简单克里金插值法3种方法构建的多路径误差插值模型,普通克里金插值法的效果最好。研究成果直观反映出在林区、多层建筑物等环境下多路径误差影响较大,还预测出未采样区域的多路径误差影响范围,该研究成果可应用于GPS观测站选址、GPS测量技术设计等领域。该文从空间分布特征的角度提出了一种新的研究多路径误差特性的思路,实现了对指定测区内的多路径误差的空间分布特征的探究。
