Broadcast Ionospheric Correction Algorithms (ICA) are used in Global
Navigation Satellite System (GNSS) single frequency receivers positioning to
compute the satellite signal delay due to the propagation through ionosphere. In
this paper two ionospheric models are considered: Klobuchar model used by the
U.S. Global Positioning System (GPS) and NeQuick model adopted by the 
European Galileo system.
The goal of this paper is to investigate the validity and efficiency of the
examined models by analyzing their performances in single frequency GNSS
