| 摘 要： | 首先简要介绍实时水汽探测技术的原理,然后采用详细的推算过程将求水汽量转化为求宽巷模糊度的问题,并利用双频P码求出宽巷模糊度。运用实例模拟分析双频P码求宽巷模糊度的精度,解释宽巷模糊度的精度随卫星高度角变化的原因。

| Abstract: | The theory of real-time GPS water vapor detecting is briefly showed.Then the problem how to get water vapor can translate into how to get the ambiguity of wide lane,and the ambiguity of wide-lane can be got by double P code.With examples,the precision of the ambiguity of wide-lane is analyzed,and the reason why the precision of the ambiguity of wide-lane varies with the elevation is explained. |

| Keywords: | water vapor the ambiguity of wide-lane double P code |
