Abstract

Within this paper, we evaluated the quality of three Global Geopotential Models entitled: EGM96,
EGM2008, and GOCO05c. The models were evaluated by using 1001 terrestrial discrete values of
height anomalies determined by Global Navigation Satellite Systems and normal heights, which we
considered to be true values within this research. In addition to the quality evaluation, we tailored
the models by using more than 80000 free air anomalies. The results obtained from the evaluation
and tailoring indicate that by using the GOCO05c it is possible to determine a set of anomaly heights
across Serbia, which are in agreement with terrestrial values with an average value of -7 cm, the
standard deviation of ±9 cm and with the range of 44 cm.
