Abstract
In recent times, one of the primary scientific objectives of physical geodesy is to determine the geoid with centimeter level and to develop the ultra high global earth’s gravity field model，and for this purpose satellite gravity gradiometry is one of the most promising techniques. This paper first comments on the main progress of satellite gravity gradiometry, and then discusses some theories and methods for refining the earth´s gravity field using satellite gravity gradiometry data.
Keywords
satellite gravity gradiometry ; satellite gravity gradiometry boundary value problem ; earth's gravity field model ; geoid
