网络RTK内插模型抗差性分析

Robustness Analysis of Network RTK Interpolation Models

空间相关误差精确建模是网络RTK技术的关键,定量分析内插模型抗差性对网络RTK内插模型的选择和优化具有重要意义。以现有内插模型为研究对象,根据误差传播定律提出误差影响因子以评价内插模型的抗差性,通过理论结合实验的方法探究不同内插模型抗差性的空间分布特征。结果表明:不同内插模型抗差性空间分布有较大差异,三角形解算单元内,不同内插模型的抗差性均满足要求。

Modelling the spatial correlation error Accurately is the key of network RTK technology.Quantitative analysis of the interpolation models＇ robustness is very important for the selection and optimization of network RTK interpolation models.The robustness of the interpolation model reflectingIn this paper,the existing interpolation models were studied,based on the law of error propagation,the concept of error impact factor is proposed to evaluate the robustness of the interpolation models.The theoretical and experimental methods were used to explore the spatial distribution characteristics of interpolation models＇ robustness.The experimental results indicate that there is a great difference in the robustness of different interpolation models in spatial distribution,and inside the triangular cell,different interpolation models both meet the robustness requirements.
