This paperwork is dedicated to the research of the quality of height anomalies derived from the Global Geopotential Models GOCO over the Serbia territory. Three different types of approaches for the same model were considered: time wise, space wise and direct approach. The quality of the mentioned models is determined by comparison with terrestrial data of height anomalies, that are relate to the second high precision leveling network of the Republic of Serbia (the period of realization of tide gauges observations for determining the vertical position of the reference surface of the height reference system of the Republic of Serbia is 1971.0 years) and European Terrestrial Reference System 1989, realization ETRF2000, epoch 2010.63. By direct comparison, it was established that all models give almost identical data on the territory of Serbia and that with the application of the model one can approximate height anomalies at the territory of Serbia with a mean value of maximum 7 cm and with a standard deviation of 20 cm. Besides of this, models are compared in their spectral domains, with each other and with the model EGM2008, by comparison their degree and error degree variances.
