| Abstract: | Aiming at the defect of single-frequency 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 spatial-temporal 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. |
| Keywords: | single-frequency GPS ionospheric delay model total electron contain(TEC) single layer model spatial-temporal characteristics |
