Calculation gravity or related parameter’s to gravity on the earth’s surface is the important parameters in the geodesy. Once method of calculating gravity on the earth’s surface, using data and or other words using space mission’s gravity. That this article using spherical harmonic coefficients obtained goce satellites (up to degree and order 250) we calculation gravity anomaly, and in the finally, with calculation of normal gravity field (on the ellipsoids); that change normal gravity is function of latitude, we can calculation gravity on the earth surface.
