Abstract: The paper presents monitoring of the geodetic displacements using the Msplit(q) estimation method. Generally, the approach is based on a multi split functional model of geodetic observations. A typical property of Msplit(q) estimation is that the estimates of the controlled point coordinates are determined by using one observation set in all measurement campaigns. In this paper the authors point out that this method may be particularly useful for adjustment of the surveying network with a low level of the mutual control observations. The precise geometric leveling measurements were used as a dataset for verification of the proposed method efficacy. As a test object the Olsztyn Castle in Poland was taken. The results of the study were compared to the classical method of the least squares estimation. Experiment results showed the important advantages of method of the estimation parameters in a split functional model of geodetic observations.
