Abstract: Atmospheric water vapor is a kind of potential water resource. It has important strategic significance for the realization of the sustainable use of freshwater resources. Ground-based GPS atmospheric water vapor tomographic technology provides quantitative basis for the study of atmospheric water vapor resources three-dimensional distribution. The technology is also important for the rational development and utilization of water vapor resources. This paper introduces the basic principle of ground-based GPS atmospheric water vapor tomographic technology; and division of ground-based GPS tomographic network is one of the critical issues for the technology. The paper discusses the methods of dividing ground-based GPS tomographic network home and abroad. It also summarizes the three main algorithms of the technology used commonly. Finally, the paper gives the existing questions of the technology and suggestions of future development.

Key words: ground-based GPS, water vapor tomographic, method of tomographic network, atmospheric water vapor resource
