First, wetdelay for the current model of low precision and made use of external inversion of wet weather data in near real time delay.
首先,针对目前湿延迟模型精度偏低,提出使用外部气象数据近实时反演湿延迟。

After the examples are analyzed, there are problems which need to be solved such as ambiguity, real-time clock bias error and the estimate method of zenith wetdelay.
通过对算例的分析,提出需要解决的问题:整周模糊度、实时钟差和天顶湿延迟的估计方法。

The dual-frequency carrier phase observation equation is built and ionosphere-free predigested, the estimate formula of zenith wetdelay is deduced with least square method.
