| Abstract: | This paper analyzed the complementary nature of the GOCE and GRACE and satellites data on the spec- trum,pointed out the need for integration of multi-source satellites gravity data, and summarized the research pro- gress and results of muhi source satellites gravity data combination,especially the GOCO and EIGEN model series. Furthermore,the problems of multi source satellites gravity data combination were studied, such as topographic effects processing, the relationship between field coefficients and data, and data weight distribution. Finally, some suggestions for multi-source satellites gravity data combination are offered. |
