| Abstract: | A combined GPS/GLONASS precise point positioning (PPP) approach is used to obtain the three-dimensional distribution of atmospheric water vapor. To verify the effectiveness of the combined GPS/GLONASS PPP, and GPS, datasets at 12 stations on 6 d were collected at the time when COSMIC RO events occurred in or around Hong Kong. The test results indicate that the number of the voxels from GPS/GLONASS PPP that are passed by the satellite rays increased by 18%, and the water vapor accuracy from GPS/GLONASS PPP is 10% higher than with the GPS PPP method. |
