The ionospheric delay is one of the main errors for the Global Navigation Satellite System (GNSS), which can range from meters to tens of meters and be corrected by dual-frequency or multifrequency combination due to the dispersive nature of the ionosphere (Hernández-Pajares et al., 1999; Hernández-Pajares et al., 2011; …
