Sažetak

High-resolution global gravity field models play a fundamental role in geodesy and Earth sciences, ranging from practical purposes, like precise orbit determination, to scientific applications, like investigation of the density structure of the Earth’s interior. Nowadays, global gravity field models, mainly derived from satellite measurements, become more and more detailed and accurate. An important task
of geodesy is to make the gravity field functionals available to other geosciences. It is necessary to calculate the corresponding functionals
as accurately as possible from a given global gravity field models and, if required, with simultaneous consideration of the topography
models determined by modern satellite methods independently from the gravity field. This paper is based on seminar papers which were
made within the subject “Determination of the Earth’s shape” in academic year 2013/2014 (Master Studies, Department of Geomatics at the Faculty of Geodesy, Chair for State Survey). Comparisons of geoid undulations and free air gravity anomalies between geopotential
models of 2006, 2008, 2011, 2012, 2013 and 2014 are presented.
