| Abstract: | An emphasis is laid on the discussion about single band receiver delay and correction in ionosphere. The general situation and impact on GPS signal in ionosphere, and the physical conditions in ionosphere are presented. GPS signal spread and influence in ionosphere are further studied. Several ionosphere delaying and correcting model are summried. The construction of Klobuchar model and its calculation are finally expounded, and the prospect for the developrent of ionosphere delaying and correcting model is made. |
