Abstract Aiming at the defect of singlefrequency GPS receiver affected by ionospheric, the effect of ionospheric delay correction with four kinds of different ionospheric models (i.e. Klobuchar, NeQuick, IRI and IGGSH) have been analyzed by use of some GPS data as the example. The spatialtemporal characteristics of each ionospheric model is analyzed statistically.The calculation results show that IGGSH model is better than the other three ionospheric delay correction models.
