doi:10.11947/j.AGCS.2016.20140648

Abstract

Abstract: Currently, the GNSS network of Yangtze River delta has being applied to monitor the water vapor above this region and research water vapor tomography. Studies have shown that the dictances between stations are large and inhomogeneous, that will make it difficult to get the high tomography precision. Therefore, a simulation test of multi GNSS observations on tomography is introduced. The multi GNSS observations are more homogeneous in spatial distribution than a single positioning system, which can reduce the space rate of the grid, especially increase the number of the grid with information at middle and high layers. The multi GNSS observation can provide more and better water vapor information which can patch up deficiency of a single positioning system. A simulated water vapor tomography is carried out, and the result shows that the multi GNSS observations could improve the accuracy of tomography, especially above the 5 km height layer of the atmosphere.

Key words: multi GNSS, slant delay, water vapor tomography, temporal and spatial distribution
