Original Abstract
New height precise Earth Geopotential Model EGM08 made possible to developed the value of the geoidal geopotential W0. This value is independent on Earths tides and others disturbances, therefore it can by used as basic quantity for many applications. Value W0 represents mean sea surface. W0 was developed from data of satellite altimetry which monitores actual oceans surface. This value is the one of four fundamental geodetic constants. This value has been accepted worldwide and is included to the IERS Conventions 2003, 2007. This value defines in principle parameters of level ellipsoid E0 (a,alfa) which best fit to the surface defined by W0. The body this level ellipsoid produces normal gravity. We developed then other important parameters for determination of the density deviations (VTT technology), i.e. values of normal gravity ge at the equator and gp at the pole on the elipsoid E0 and from many other parameters the value of parameter beta. All parameters above was used for development of VTT technology are supplied by GPS/leveling data, that enable to create so-called density deviation maps at any place in the World. In comparison with gravity anomalies the density deviations represent more precise density anomalous places in the Earths crust. A using and construction of the density deviation map is applied at two from geologically different regions – the Western Carpathians and the Central African Rifts.
