Introduction. The article is dedicated to the choice of reference (source) points as a basis for geodynamic monitoring. Monitoring can be both regional, of the Ural region, for instance, and local, covering a group of deposits and an enclosing massif.
Relevance. As soon as a massif has got a hierarchical and blocky structure and constant mobility, caused by the total effect from natural and technogenic factors, the choice of reference points, which are free from the effect of strains, is a relevant problem.
The idea of the research. For actual estimate of the spatial-temporal stability of the reference points, it is proposed to establish a geodetic tie to the IGS global network with further analysis of velocities and directions of their proper movements relative to the neighboring points.
Methodology. Based on the obtained data, the most stable reference points are detected; their velocities and directions of spatial displacements are compared with the model ones in ITRF2014 system, the background being eliminated.
Results. Actual displacement vectors have been determined for a range of IGS and FAGS stations and the base point of temporary accommodation facilities. According to the outcome of a series of earthquakes in the neighborhood of the town of Katav-Ivanovsk, the stress-strain state of the massif has been examined.
