This paper presents an analysis of the capability of NeQuick 2 model to reproduce the slant TEC values measured at stations worldwide distributed. The data used cover complete years of high (2000) and moderate solar activity (2004). A comparison with GPS Ionospheric Correction Algorithm (ICA), ...
NeQuick2 model did not respond to the effects associated with geomagnetic storm. There is need to include storm related parameters in the prediction of vTEC using NeQuick2 model. Introduction The ionosphere is a region of the earth’s atmosphere in the altitude between 60 and 1000 km (Langley,...
In this paper, we focus on the evaluation of the IRI-2016 and NeQuick-2 topside electron content specification by a comparison with the multiple ground-based and space-based GPS observations. The multilevel EC data deriving concurrently from the ground-based GPS, the COSMIC GPS RO soundings and...
NeQuick-G is the emerging model developed for Galileo, it over-performs Klobuchar model, in the both measurement and position domains. These improvements are compensated by a higher computational load which is fundamental, for mass market devices. The main goal of this work is to identify a ...
