    Abstract
  • Ionospheric delay is one of the major error sources for navigation signal in its propagation path.Therefore,the understanding of the GNSS ionosphere model correction accuracy has a practical significance.In this paper,ionosphere correction models are introduced.With high precision global ionospheric maps as a benchmark and the ionospheric correction parameters in 2014,the correction accuracy of the three systems ionospheric delay is evaluation and analyzed.It is found that the correction rates of several current GNSS ionospheric correction model have reached about 65% to 75%.Through comparison of the second edition NeQuick model and the first edition NeQuick model which Galileo system used,it is found that there is no significant improvement in accuracy.GPS Klobuchar eight parameters model has a high precision at 25°-45°N in the northern hemisphere midlatitudes,but it has a poor distribution and lower accuracy in other regions of the world.However,NeQuick model global correction rate distributions are more even and smooth than those of the other models.
