Abstract

The ionospheric delay for GNSS is an effect difficult to predict and thus difficult to model. The Klobuchar model which is the standard correction model for single frequency GPS receiver has its limitation: it can only correct 50% of the global ionosphere error. The NeQuick model is a good candidate to be the standard ionospheric model for single frequency Galileo receivers. Thanks to the concept of IPRE developed in [1], it is possible to predict the performances of the NeQuick model using different configurations, in the case the ionosphere error is the dominant one and in the case it is not the dominant one. This paper describs the results by presenting a comparison using the first two statistical moments: the mean and the variance. The time series are providing interesting results especially when looking at some seasonal effects which in the case of NeQuick tends to be reduced and tend to center the distribution of the ionosphere residual error.
