This paper presents the determination of the vertical deflection components using the Global Geopotential Model EGM2008. The components are defined in two groups of points: 4083 points are relatively correctly distributed across the territory of Serbia and 46 Laplas and geoid points defined in Serbia in the past century, from the set of institutions. All presented determinations in this paper are related to the Geodetic Reference System 1980 (GRS80), with the coordinates of all the points used to refer to the International Terrestrial Frame 1996 (ITRF96). Analysis of the results of the determination showed that the EGM2008 can be used to approximate the astrogeodetic determination with the agreement of several arc seconds.
