A method of the improvement of the total station observations 3D adjustment by
using precise geoid model is presented. The novel concept of using the plumb line direction
obtained from the precise geoid model in combined GPS/total station data adjustment is
applied. It is concluded that results of the adjustment can be improved if data on plumb line
direction is used. Theoretical background shown in the paper was proved with an experiment
based on the total station and GPS measurements referred to GRS80 geocentric reference
system and with the use of GUGIK2001 geoid model for Poland.
