Analysis of Three-Dimensional Water Vapor Tomography Using Integrated GPS/GLONASS Observations
Abstract Based on data collected for six days at fifteen stations of Hong Kong satellite positioning reference station network (SatRef) in 2014, we combine GPS and GLONASS to perform a three-dimensional water vapor tomography experiment. The results show that the integrated GPS/GLONASS system can significantly increase the number of voxels which are passed through by the signals. The system improves the accuracy of distribution of water vapor by an average improvement rate of 36% in comparison with a GPS-only system.
