Transformation between celestial and terrestrial reference systems: definition of Earth orientation parameters (EOP), determination of EOP by means of space geodetic techniques; Theoretical background: rotation of a rigid Earth, rotation of a deformable Earth, polar motion, changes of the rotation speed, precession-nutation. Modeling of geophysical effects: angular momentum approach, torque approach, excitation functions.
