Jiao Mengmei1 Zhang Jingfa1 Jiang Wenliang1 Yan Rui1,2(1.Institute of Crustal Dynamics,CEA,Beijing,100085)(2.Institute of engineering mechanics,CEA,Ha'erbin,150080)  
The satellite gravity has advantages of high precision and high resolution in determining the global earth gravity field and its temporal variation;therefore,it provides a new approach in geodesy and geophysics science.In this paper,we briefly introduce the development of satellite gravity,analyze the four kinds of satellite gravity measurement techniques,and discuss their advantages and disadvantages according to the implementation of gravity satellites.Finally,the application of satellite gravity in earth science is simply discussed.
