Abstract:

The present report is a continuation and conclusion of two previous OSU-DGSS reports AD-A108 999 and AD-A099 015. It treats the solution of Sasao, Okubo and Saito 1980, which is the simplest and most straight forward solution of Molodenskys liquid core problem Part A. In Part B, a relatively little known variational principle of Poincare is derived and applied to a unified deduction of the equations of Sasao et al. Part C provides explicit expression for lunisolar nutation and polar motion for the principal terrestrial axes the rotation axis, the figure axis, the mean Tisserand axis, the angular momentum axis, and the axis associated with the Celestial Ephemeris Pole as adopted by the IAU in 1979, taking into account liquid core effects.
