A simple and autonomous ionospheric correction estimation method in SPP allows independence from external products delivering information on the ionospheric delay. The elaborated mathematical model improves navigation solutions in reference to the SPP approach with the Klobuchar algorithm and ensures results on a similar level compared to the IGS TEC map. The numerical experiment was carried out utilizing real GNSS code data and a MATLAB environment.
