Nonrigid-Earth Rotation Solution

Abstract

The accuracy of the rigid-Earth solution SMART97 is 2 microarcseconds over the time interval 1968-2023. To obtain a nonrigid-Earth solution, the authors use the transfer function of Mathews (1999). The perturbations of the third component of the angular velocity vector are taken into account.
