The Hamiltonian theory of Earth rotation, known as the Kinoshita-Souchay theory, operates with nonosculating Andoyer elements. This situation parallels a similar phenomenon that often happens (but seldom gets noticed) in orbital dynamics, when the st

In recent years several sets of potential corrections to the current precession and nutation models IAU2006 and IAU2000 have been obtained by different teams, in whose derivation have participated a number of members of the IAU/IAG JWG on Improving t

At present, the most precise method for obtaining reliable observations of Celestial Pole Offsets (CPO) is through the use of Very Long Baseline Interferometry (VLBI). The CPO data includes a variety of components, such as the free core nutation (FCN

The positions of the radio sources in the ICRF3 catalog, representing the newest realization of the Celestial Reference Frame (CRF), are given as a time invariant coordinate pair. However, systematic changes of source positions at different spacial a
