| Abstract: | Satellite gravity gradiometry is a new domain of studying the detection of gravity gradients in space and their applications, in particular, suitable for detecting the short wavelength characteristics of the earth's gravity field At present it is still at the stage of developing the ultra-sensitive tensor gradiometer and carrying out the pre-research of applications. This paper studies the importance and advantages of satellite gradiometry. The particular role of gravity gradiometry in inertial navigation and the refinement of the earth's gravity field model have been expounded. And many uses of satellite gradiometry in gravity survey, geodyna-mics and earthquake, prediction research have been investigated. In the meantime, the great significance of it in monitoring the microgravity environment, examining the gravity field continuation theory, and improving the analysis subjected orbital vehicle to gravitational force have been discussed. |
