| Abstract: | Ionospheric error is one of the main errors impacting precision of Global Navigation Satellite System(GNSS) when it is used in precision navigaton and orientation.So it is very important for us to study ionospheric models.In this paper,ionospheric models are divided into classic model and modernistic models.At the same time,classic models are compared by each other.In addition,hot topics,existing problems and development direction about current ionospherec models is introduced especially. |
