This paper presents the evaluation and comparison test of a series of global geopotential models (GGM) using available terrestrial data over the territory of Montenegro. Using the model of Gravity Observation Combination 02S and 03S (G00002S and GOCO03S) with three different approaches (space-wise approach, time-wise approach, and direct approach) as well as the model of the Earth Gravitational Model 2008 (EGM08) and Earth Gravitational Model 1996 (EGM96) the anomalies of free air at 1293 points of gravimetric survey of Montenegro were determined; as well as the height anomalies at 46 points for which the discreet values of height anomalies are known. The discreet values of height anomalies were calculated as differences between orthometric heights, determined by high precision levelling and the ellipsoidal heights determined by the global positioning system (GPS/dh); and at the points of gravimetric survey of Montenegro, the free air anomalies related to the Geodetic Reference System ...1980 (GRS80) and to the International Gravity Standardization Net 1971 (IGSN71) were determined. The data used in this paper are the data of gravimetric survey of former Socialistic Federative Republic of Yugoslavia, and the data of the height anomalies discreet values are data collected in March 2015 for further scientific research, particularly for geoid/quasigeoid determination for Montenegro.
