Construction of normal equations mission for processing data GOCE

With the advent of satellite technology significantly increased amounts of measurement data. In this regard, there is a need in the selection algorithm to work with so many information.
In this article discusses an algorithm for constructing the matrix of normal equations by Satellite gradiometry (vertical gradient) to further define the harmonic coefficients of the gravitational field of the Earth. Formation matrix is using the method of partial sums of Gauss, the accumulation of elements of the normal equations.
