Název v původním jazyce

Combination of heterogenous geodetic data in detailed gravity field modelling

Popis výsledku v původním jazyce

In this study a detailed gravity field is represented by the disturbing gravity potential and its first and higher order derivatives. These characteristics play an important role in geodesy providing a link between geometric and gravity space, but, undercertain conditions, they can also contribute to structural interpretations of geodynamic phenomena. Their estimates are based on a combination of different observables coming from high degree/order harmonic expansion of the EGM08 earth gravitational model (2160/2160), from a large number of directly observed astronomical coordinates, GNSS/levelling based height anomaliesas well as from an extremely detailed anomalous gravity field description by point gravity anomalies. Computations are performed for two test areas located in central Moravia, the Czech Republic. Accuracy assessment and investigations towards contributions of the terrestrial gravity data are accomplished by reflections about an optimal distribution of observables.
