Lopushansky O. Construction of the models of Earth's gravity field from satellites data

From 2000 to 2009 years were launched satellites CHAMP, GRACE and GOCE, which are classified as satellites LEO (Low Earth Orbit), the height of the orbit is lower than 500 km. The choice of algorithm, which allows the determination of harmonic coefficients geopotential from gravity gradient tensor components, which is measured as part of the modern approach satellite mission GOCE gradientometry, became significant task for improving long and mean components of the gravitational field via data processing. As a result, in this thesis two version of the corresponding harmonic coefficients Cnm, Snm (gravity field models GOCE-LP01s and GOCE-LP02s up to degree/order 250) were derived based on the second Neumann method including the construction of the corresponding Gauss grid.
