Earth Rotation From Lunar Distances.

Abstract

A mathematical description of the orientation of the Earth's surface in space is conventionally broken into several distinct components: the precession and nutation of the Earth's angular momentum vector in inertial space, the motion of the instantaneous rotation axis of the crust relative to the angular momentum vector, the motion of the Earth's crust relative to the instantaneous rotation axis (or as one more commonly describes the polar motion, the motion of the axis with respect to the crust), and the instantaneous speed of rotation of the crust.
