With the improvement of Beidou navigation satellite system (BDS), real-time monitoring of atmospheric water vapor content based on BDS has become a research hotspot. BDS and GPS observation data of seven MGEX CORS stations were processed using GAMIT10.71 software and the atmospheric precipitable water vapor (PWV) was estimated. The PWV/BDS using Beidou final precise ephemeris and ultra-rapid precise ephemeris was respectively compared with PWV/GPS using IGS final precise ephemeris. The experiment results showed that the PWV/BDS is in good agreement with the PWV/GPS. The standard deviation (Std) of the PWV/BDS based on Beidou final precise ephemeris and ultra-rapid precise ephemeris are respectively 2.91mm and 3.97mm. And the RMSE of the PWV/BDS based on Beidou final precise ephemeris and ultra-rapid precise ephemeris are respectively 3.97mm and 3.85mm with the PWV/GPS as the reference value.
