摘　　要：在网络RTK应用中,当基准站和流动站之间的高差较大时,流动站定位精度会降低,甚至会导致流动站模糊度无法固定,此种情况对于在我国地形起伏明显区域内的网络RTK经常发生。针对此问题,本文提出基于高差的综合误差内插模型,用此模型对误差进行内插,并和平面内插法、三维内插进行了对比。In the Network RTK applications,when the height difference between the base and rover is large,the rover positioning accuracy will be reduced,and even lead to ambiguity of the roving stations can＇t be fixed,resulting in unable to position.This situation happened frequently in our topography areas within the region of RTK system.To solve this problem,the error interpolation model based on the height difference is proposed in this paper,and the Plane,3D interpolation are compared.
