Analysis on Ionosphere Interpolation Models
摘要
Abstract
Common ionosphere delay interpolation models include linear combination model,distance based linear interpolation model,linear interpolation model and low-order surface model,et al.The basic principle and method of these kinds of models were introduced in detail.The measured data of Hebei CORS were analyzed,and the comparison of interpolation accuracy between different models was conducted.The results showed that the interpolation accuracy of LSM model was a little higher than the other three kinds of models whether the rover in network or outside the network,and the interpolation accuracy of the other three kinds of models was appropriate.Whether the rover in network or outside the network,the change of the accuracy of LSM model was the smallest,that of LIM was the second,and that of LCM was the biggest.关键词
