Motion of the Earth's centre of mass. Physical principles
It has been found that the residual (Chandler) motion of the Earth’s rotation pole results from the forced translational motion of the Earth’s rotation axis relative to the geographic axis. The Earth’s rotation axis moves parallel to itself without changing the angle of inclination to the ecliptic p...
