Preliminary unification of Kronsztadt86 local vertical datum with global vertical datum

Adam Łyszkowicz, Joanna Kuczyńska-Siehień, Monika Biryło


The study concerns computation of the gravity potential difference between the Kronsztadt86 datum and the global vertical datum. This method is based on the use of ellipsoidal heights from satellite observations, normal heights obtained from the conducted leveling campaign and quasigeoid/ellipsoid separations computed based on the EGM2008 model. The obtained results indicate that there are substantial differences in the estimated value of the parameter DW, computed from three different satellite networks: POLREF, EUVN-DA and ASG-EUPOS. The parameter was determined with sufficient accuracy and the applied systematic error model has low efficiency. The computations reveal that the best value of DW for the territory of Poland is 0.43 m2s-2.
