In the given article the different modern models of the gravity field of Earth for determination of exactness of interpolation of height of geoid / quasigeoid for space on the territory of Ukraine are examined. With that purpose the comparison of model of geoid and gravity field of Earth for information satellite leveling of 44 points 1 and to 2 classes of geodesic network of Ukraine are executed.The results of researches rotined that a model EGMO8 is the most perfect than all existent models of geopotential for territory of Ukraine. Exactness of height of quasigeoid is characterized at the level of ± 10 sm.
