Opis

Since the Czech edition was published four years ago, the authors have revised the original text tobring it up to date. During these four years, thanks to satellite altimetry the accuracy of the global descrip tion of the gravity field (model GEM-T2), of the fundamental astro geodetic constants, of the principal moments of inertia of the Earth and, in particular, of their differences, of the precession constant, and of a number of other dynamical parameters of the Earth have been improved. The authors have included most of these improvements in the revised English edition. They have, of course, also made factual, formal and other corrections and have modified some of the figures. Additions to the index and references have also been made. Praha, Czech Republic M. BuRSA and K.

O autorze

The applications of Satellite geodesy include the observation and measurement of the latest changes on the Earth and extend to the reconstruction of inhomogeneities in the Earth's interior and related dynamic processes. The last aspect is the subject of the book, which combines for the first time space geodesy, geodynamics and physics of the Earth's interior.
