| 摘 要： | 基于一定的大气折射率剖面模型和搜索方法，可以由GPS天顶延迟反演大气折射率剖面。利用上海气象站的探空数据和上海IGS站的GPS数据，对基于单站地基GPS天顶延迟的大气折射率剖面反演方法进行了验证。结果表明，根据目前处理得到的天顶延迟，反演剖面与实际剖面吻合较好。 |
| 关 键 词： | 地基单站GPS 天顶延迟 大气折射率剖面 Hopfield模型 指数模型 |

| Abstract: | Given the model of atmospheric profile and searching algorithm,the atmospheric refractivity profiles can be retrieved from zenith total delay(ZTD) of GPS receiver.Based on the radiosonde data of Shanghai weather station and GPS data of Shanghai IGS station,the method has been verified to retrieve atmospheric refractivity profile based on ZTD of singular ground-based GPS receiver.The comparison shows that the inversion profiles have good agreement with radiosonde profiles. |
| Keywords: | Singular ground-based GPS zenith total delay atmospheric refractivity profile Hopfield model exponential model |
