Review on the Domestic Applications of GRACE Gravity Satellite Data

In order to improve the structure of the deep earth and track the change of the surface quality of the earth,combined with the advantage of GRACE gravity satellite in the observation of high-accuracy earth gravity field,the corresponding research have been made based on the GRACE gravity satellite data.This paper summarized the application status of GRACE satellite and its data products through several aspects like the polar alpine glaciers,earthquakes,earth gravity field inversion and hydrology etc.o,the error sources affecting the inversion accuracy of GRACE data are summarized and the corresponding processing method and advises are given.Finally,the problem of the further application of GRACE gravity satellite data are discussed and summarized,which has a certain reference value for the follow-up research.
