| Abstract: | This paper deals with three gravity satellites,namely CHAMP,GRACE and GOCE.Satellite gravity data are widely used in such fields as the recovery of the earth’s gravity field,the land water storage,the study of the geoid change,the elastic thickness,the crustal thickness,the gravity variance before and after earthquake and the crustal movement.Lots of successful and valuable research results were obtained.It is considered that the satellite gravity survey technology is by for superior to traditional gravity survey and will surely have larger application space. |
