Abstract

Abstract: In order to enhance the ability of geodesy to serve human social activities, building an Earth system including the earth's gravity field and maximizing the benefits of Earth system simulation and prediction will greatly promote the development of Earth system science and enhance the service capabilities of the discipline. The earth hexagonal grid system is widely used in the earth system, and it has advantages in the realization of earth gravity field modeling, data processing, multi-source data fusion, etc. This paper summarizes the limitations of traditional geographic grids and the advantages and potential of spherical hexagonal grids in the applications of the earth's gravity field. The study of the earth's gravity field under the hexagonal grid system will play an important role in improving the efficiency and accuracy of the earth's gravity field solution and in the unification of multiple earth system models.

Key words: hexagonal grid system, Earth system, Earth's gravity field
