## The use of second neumann method for modelling the Earth's gravity field based on satellite gradientometry data

The project of European Space Agency and a recent achievement in satellite geodesy, the GOCE satellite mission (Gravity of Field and Steady-State of Ocean Circulation Explorer) exploits a method of satellite gradientometry. Gravitational field of the Earth is usually represented as a finite series of spherical harmonic functions, the model containing a finite number of coefficients, Cnm, Snm. The coefficients Cnm, Snm are derived in our work, based on the second method of Neumann and the Gauss-Legandre quadrature decomposition.
