Description:
The UQG2007 quasi-geoid model is a hybrid solution for the Ukraine and Moldova. It was derived
from the same gravity dataset used for the computation of the UQG2006 gravimetric model with the
addition of about 3000 GPS-levelling quasi-geoid heights. The reference global geopotential model
was again EIGEN-CG01C up to degree and order 360, but the terrain reductions were based on the 3"x3" digital
terrain model SRTM3 having over one order better accuracy than the 1'x1' DTM GEBCO. Like UQG2006, the solution
is based on the application of the collocation method with regularization in the framework of a remore-restore
procedure. The final model, with a grid resolution of 2'x3', represents the geoidal heights above the GRS80
ellipsoid in the Baltic 1977 system. The comparison of the UQG2007 model with independent GPS/levelling control
points shows a good agreement with an error rms smaller than 4 cm.
