Rezumat

The project of modeling a gravimetric quasigeoid for Romania is carried out in stages, based on the gravimetric measurements in the area of each county, in the gravimetric points of the 0, 1st and 2nd order gravimetric network, in the checkpoints (with GNSS/levelling data) and also in the new designed points.
The remove-compute-restore technique was used to remove the long-wavelength component from Global Geopotential Model (GGM) and effect of the short-wavelength signal by applying terrain corrections, to compute residual geoid heights, and to restore the effect of the GGM and topography.
In this article are presented the main activities that took place in the period 2016-2021 for creating the projects in the counties of Romania and the results obtained till now as well as the perspective for the next years.
