New height precise Earth
Geopotential Model EGM08 made it possible to develop the value of the geoidal geopotential W0.
This value is independent on Earth’s tides and others disturbances, therefore
it can be used as basic
quantity for many applications. Value W0 represents mean sea
surface. W0 was developed from data of satellite altimetry
which monitores actual ocean’s surface. This value is one of the four
fundamental geodetic constants. This value has been accepted worldwide and is included to
the International Earth Rotation and Reference Systems Service Conventions
(IERS Conventions) 2003, 2007. This value defines in principle parameters of
level ellipsoid which best fit to the surface defined by W0.
The body of this
level ellipsoid produces normal gravity. We developed other important
parameters for determination of the density deviations (VTT technology), i.e. values of normal gravity geat the equator and gpat the pole on the elipsoid E0 and the value of parameter β. All
parameters above 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 Earth’s crust. A construction of
density deviation map is applied at two from geologically different regions—the Western Carpathians and the Central African Rifts.
