Abstract: It is well known that the reference points’ stability is a very important issue in the geodetic methods of determining the displacements. The methodology of the geodetic deformation analysis requires to conduct the research of determining a stable reference datum, before the deformation indicators will be determined. However, the methods of determining the reliable values of the monitored point displacements, despite the instability of the reference points, can be considered as a supplement to the classical deformation analysis strategies. In this paper, we present application of method of the estimation of parameters in a split functional model to determine the vertical indicators of leveling network deformation, in which reference datum was unstable. The computations were realized on the geodetic control network designed in the area of the Old and Main City of Gdansk.
