doi:10.13474/j.cnki.11-2246.2018.0022

Abstract

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.

Key words: ionospheric delay, Klobuchar model, NeQuick model, TSE model, positioning accuracy
