| 摘 要： | 比较了Saastamoinen模型、UNB3模型和改进的Hopfield模型受纬度、高程和时间影响的不同特性。采用SuomiNet提供的数据进行计算验证,给出适合水汽反演的对流层延迟模型。依据估计的对流层天顶湿延迟反演大气综合水汽含量,通过与网解值对比,验证非差精密单点定位技术反演的大气综合水汽含量,能够达到双差网解方式的精度。

| Abstract: | In this article, different characteristics affected by the factors of elevation, time and latitude among three tropospheric refraction models of Saastamoinen, UNB3 and modified hopfield were compared. Based on the experiment results, the most appropriate model was chosen for atmospheric water vapor determination. The estimated water vapor was compared to the results provided by SuomiNet, and a good agreement was showed, which validated the accuracy of PPP-inferred IWV. It demonstrated that GPS water vapor detected by using PPP technique can reach the precision of network solution. |
