Abstract
At present, the information on the deflection of the vertical (DOV) is obtained by means of modern geopotential models. The authors have obtained the DOV model values in the Western Siberia Region; the results of their components comparison are analyzed in the paper. The said components have been calculated on the basis of global geopotential model EIGEN-6C4, as well as of the results of astrogeodetic measurements taken in the Western Siberia Region. The survey results showed that in plane areas standard deviations of model DOV from the on-ground values obtained by traditional astrogeodetic method, do not exceed 1 arc sec.
