Abstract: A method performs a correction of an ionospheric error affecting pseudo-ranges measurements in a GNSS receiver receiving a plurality of satellite signals from a plurality of satellites of a constellation of satellites. The method is part of a navigation processing procedure performed at the GNSS receiver. The method utilizes pseudo range measurements previously calculated by the GNSS receiver, obtained from a plurality of carrier signals in the satellite signals. The method includes performing a correction procedure of the pseudo-range measurements, by calculating ionospheric error correction values for the pseudo-range measurements.
