The determination of gravity field Earth parameters by gradiometry observations

The paper presents the goals and objectives of the GOCE mission, the used measurement information and data processing strategy in determining the parameters of the gravitational field of the Earth, as well as products obtained as a result of mathematical processing of data at various levels. In addition, the coordinate systems used in the processing of measuring information are considered, the equation of observables of gradiometric measurements is analyzed and an algorithm for calculating the coefficients and free terms of the equation of observable is developed in the case of using the direct approach in determining the parameters of the gravitational field of the Earth.
