quasigeoid surfaces obtained from several Global Geopotential
Models (GGM) relative to the official quasigeoid solution
of Serbia (SQM2011) and GNSS/dh observations for the
territory of Serbia. Therefore, validation and comparison of
the derived surfaces from the three GGM’s were made based
on comparisons of height anomaly derived from GGM’s,
SQM2011, and the GNSS/dh observations at the points
of the high-precision leveling network. The selected publicly
available GGM’s in this study are GOCO05c, SGGUGM-2, and XGM2019e. Primarily, at 1001 points of
the high-precision leveling network, the differences between
GGM and GNSS/dh height anomaly were calculated. The
final translation parameters were calculated in the iteration
procedure, which was then used to calculate the final values
of the estimated height anomaly for all GGM’s at 143207
points of the regular grid of spatial resolution 0.5' × 0.5'
on the entire territory of Serbia. From the estimated height
anomaly, three GGM-derived surfaces were modeled relative
to the SQM2011. According to the results of the calculations,
SGG-UGM-2 provides the best approximation of the quasigeoid SQM2011, where the remaining differences have a
mean value of 0.01 m, a standard deviation of 0.06 m, and
a span of 0.67 m",
