Kronstadt Height Datum on the Territories of the Czech and Slovak Republics and its Connection to a Global Vertical Reference Frame

Kronstadt Height Datum on the Territories of the Czech and Slovak Republics and its Connection to a Global Vertical Reference Frame

Paper in proceedings (conference paper)

ABSTRACT: The development of Global Vertical Reference Frame (GVRF) is an actual topic to be solved by the IAG (International Association of Geodesy). In the past was developed methodology for determining the vertical shift of Local Vertical Datums over areas covered by GNSS/levelling sites. This methodology was applied to the Kronstadt Height Datum (KHD) on the territory of the Czech and Slovak Republics. Using the gravity field models EGM2008 and EIGEN-6C4 and the four primary constants (GM – geocentric gravitational constants, ω – nominal value of the angular velocity of the Earth´s rotation, J2 - the second zonal Stokes geopotential harmonic coefficient, W0 – geoidal potential), the vertical shift of KHD to actual geopotential value W0= 62 636 856.0 m2s-2 and 62 636 854.0 m2s-2 has been determined. For solution above there is necessary to define the mean Earth´s level ellipsoid parameters.
