摘要
讨论了单频接收机的电离层延迟的改正和有关电离层的概况及对GPS信号的影响 .对电离层的物理概况作了归纳 ,并就GPS信号在电离层的传播及其影响进行了探讨 ,总结了几种电离层延迟改正模型 .最后集中讨论了克罗布歇的模型构建及其解算 ,对模型的优缺点进行了总结 。
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.
