基于全球定位系统（GPS）的可吸入水汽（PWV）估计已被广泛研究并用于气象应用。然而，使用新兴的北斗导航卫星系统（BDS）的PWV估计是非常有限的。本文介绍了利用精密单点定位（PPP）方法进行地面BDS观测的PWV估计策略和结果评估。2013年期间分布在亚太和西印度洋区域的10个台站的北斗系统和全球定位系统数据使用PANDA（定位和导航数据分析）软件包进行处理。BDS-PWV和GPS-PWV分别来自仅BDS和仅GPS观测。仅BDS和仅GPS之间的PPP定位差异显示标准偏差（STD）
Precipitable water vapor (PWV) estimation from Global Positioning System (GPS) has been extensively studied and used for meteorological applications. However PWV estimation using the emerging BeiDou Navigation Satellite System (BDS) is very limited. In this paper the PWV estimation strategy and the evaluation of the results inferred from ground-based BDS observations using Precise Point Positioning (PPP) method are presented. BDS and GPS data from 10 stations distributed in the Asia Pacific and West Indian Ocean regions during the year 2013 are processed using the PANDA (Position and Navigation Data Analyst) software package. The BDS-PWV and GPS-PWV are derived from the BDS-only and GPS-only observations, respectively. The PPP positioning differences between BDS-only and GPS-only show a standard deviation (STD)
