Abstract:

The authors study the approaches to selecting the type of state reference system, the fundamental features, and the advantages of using their different kinds. A scheme is presented for implementing conversion from various coordinate systems to the state one, the GSK-2011, in which the latter acts as dynamic. The software implementation of the data transformation, taking into account the movement of the Earth`s crust and including its model constructed for the territory of the Russian Federation is described. Developed by the authors it is used to calculate the coordinates of points in the GSK-2011 system for different observation epochs. The results of the software verification are presented, and their comparison with various services and catalogs is carried out. The analysis of the results for points belonging to different lithospheric plates shows the greatest differences in the determined coordinates for Okhotsk (the Okhotsk Sea) lithospheric plate

Keywords:

coordinate transformation, dynamic reference frame, Earth's crust movements, geodynamics, lithospheric plates, semi-dynamic reference frame

The Research was carried out within the framework of the component of a research project "GEOTECH-QUANT-3" with the aim of improving the accuracy of coordinate-time determinations in the territory of the Russian Federation
