The current determination of quasigeoid is largely based on gravimetric observations, which in general do not cover areas equally. That causes decreasing in quality of quasigeoid determination in those areas that are sparsely covered (surveyed) by gravimetric measurements. This situation was occurred on territory of the Slovak Republic in the Tatra Mountains area where gravimetric observations were performed only in some valleys and crests and from Polish side were only applied average values of Bouguer gravity anomalies with a 5' x 7.5' grid spacing (10 km x 10 km) which were transformed to average free-air gravity anomalies. To testing precision of the determined gravimetric quasigeoid it's desirable to use independent method such as astronomical method. Essentially is concerned with comparison astronomical and gravimetric of vertical deflections in the given region and with modelling of the differences between astronomical and gravimetric vertical deflections.
