Abstract
The Earth’s principal axes and principal moments of inertia, was estimated from the least-squares adjustment of gravitationalharmonic coefficients of second degree of recent global Earth gravity models including EIGEN-1S solution and thedynamical ellipticity derived from the precession constant through VLBI. The estimation was made for the time-independentcomponents (at epoch) of the Earth’s inertial tensor and the time-dependent components of the tensor of inertia, based ongiven information on the secular and periodic variations of harmonic coefficients of second degree.
