| 摘 要： | 针对电离层延迟误差对定位精度的影响，本文将泰勒级数展开应用于电离层延迟的求解过程中，提出了一种基于泰勒级数展开的电离层改正模型（TSE模型）。将该模型与传统的Klobuchar模型和NeQuick模型在VTEC的求解精度和定位精度上进行了对比分析，用IGS网站提供的测量数据，通过仿真试验验证，得出了TSE模型在提高定位精度上具有较好的可行性与时间适应性的结论。

| Abstract: | Aiming at the effect of ionospheric delay error on the positioning accuracy, a Taylor series expansion model ( TSE model) based on Taylor series expansion is proposed in this paper.And we compare this model with the traditional Klobuchar model and NeQuick model in the accuracy of VTEC and positioning accuracy.Using the measurement data provided by IGS website, the simulation results show that the TSE model can improve the accuracy of positioning and have better time adaptability. |
