Anotācija The article describes the method and computation results of Ulaanbaatar region quasi-geoid model, UBQGEOID2018, based on global gravity field model EGM2008, GNSS and levelling points in Baltic Height system 1977 and derived deflections of vertical data. The DFHRS (Digital Finite-element Height Reference Surface) software v.4.4 [2] has been used for this purpose, which allow the direct conversion of ellipsoidal heights to normal heights and based on parametric modelling of the HRS. The principle of vertical deflections measurements by digital zenith camera is included in this paper based on rotation matrices: the rotation matrix between local astronomical vertical system and local geodetic vertical system is introduced. The next stage of the development version 5.x and related research is also described and the conceptual formulas are introduced.
