Hypothesis of the Earth’s Body Expansion and Global Plate Motions from the Point of View of Contemporary Geodetic Reference Frames

Abstract

Based on contemporary observation technologies of space geodesy, annually renewed geocentric reference frames are created. These frames are defined by the co-ordinates of the sites and their time (annual) changes. Using the field of time changes the hypothesis of the Earth’s body expansion is checked. Also the model of global tectonic plate movements NUVEL1 is modified and the residual changes at the region of European continent are discussed.
