摘要
At present, information on deflections of the vertical (DOV) is obtained by means of modern global geopotential models. The authors have derived DOV model values in the Western Siberia region. The results of the comparison of the DOV model values calculated with the use of the global geopotential model EIGEN-6C4 and the astrogeodetic measurements taken in the Western Siberia region are analyzed. The study has shown that in plains, standard deviations of DOV model values from the terrestrial data obtained by traditional astrogeodetic method do not exceed 1 arcsec. © 2018, Pleiades Publishing, Ltd.
