Modelling the effects of topographic masses which bear local changes of the gravity field is exceptionally important in the contemporary scientific and practical implementations. The topography effect in this paper is analysed by the digital terrain model of the Republic of Serbia, developed on the basis of the topographic map at the scale of 1:25 000 and by the hypothesis on the equal density of surface layers of the Earth crust. The shortwave characteristic as an impact of the local topography was analysed in parts with different topography for the region of Belgrade and Paraćin. The gravity field parameters were determined in points of the reference GPS network of the Republic of Serbia and points of the Paraćin basis, with the purpose of comparing gravimetric vertical deflections with astro-geodetic vertical deflections.

Modeliranje utjecaja topografskih masa, koje nose lokalne promjene gravitacijskog polja, od izuzetne je važnosti u suvremenoj znanstvenoj i praktičnoj primjeni. U ovome radu utjecaj topografije analizira se digitalnim modelom terena Republike Srbije koji je razvijen na osnovi topografske karte mjerila 1:25 000 te uz pretpostavku jednake gustoće površinskih slojeva Zemljine kore. Kratkovalna karakteristika, kao utjecaj lokalne topografije, analizirana je u dijelovima s različitom topografijom za područje Beograda i Paraćina. Parametri gravitacijskog polja određeni su u točkama referentne GPS-mreže Republike Srbije te u točkama baze u Paraćinu, u svrhu usporedbe gravimetrijskih otklona vertikale s astro-geodetskim otklonima vertikale.
