To the problem of elimination of invariance loss effects in the evaluation of deformation fields of the earth using GNSS-data
Aim. Solving the problem associated in using GNSS monitoring data in the ITRS to evaluate deformation of fields of the Earth in terms of elimination of invariance loss errors. Methodology and results. The problem is considered in the context of the geophysical nature of the ITRS in conjunction with the global deformation field of the Earth. The attention is focused on the consequences of deformation of the ITRS system, which manifests itself as invariance loss effects in the interpretation of deformation fields.
