The Slepian localized spectral analysis method is introduced and its mathematical characteristics are analyzed.Grünbaum operator is introduced to improve the computational efficiency and stability.Then,the formulas of Slepian method for recovering the gravity field with satellite gravity gradiometry data are educed and numerical analysis are done.The results show that,Slepian function is orthogonal in both the sphere and the belt,and its spectral energy distribution characteristic is in accord with the orbit characteristic.Also,the accuracy of low order coefficients in Slepian domain is less influenced by polar gaps than that in spherical harmonic domain.However,the direct contribution of Slepian method to the improvement of geoid is limited.
