Abstract: A method corrects an ionospheric error affecting pseudo-range measurements in a GNSS receiver receiving a plurality of satellite signals from a plurality of satellites of the constellation of satellites. The method is performed in a navigation processing procedure performed at a GNSS receiver, receiving pseudo-range measurements previously calculated by the GNSS receiver obtained from a first carrier signal and a second carrier signal in the satellite signals, in particular in GPS bands L1 and L5. The method includes performing a correction procedure of the pseudo-range measurements including applying to the pseudo-range measurements corrections for predictable errors obtaining corrected pseudo-ranges and applying to the corrected pseudo-range measurements a further ionospheric error correction calculation to obtain further ionospheric error correction values.
