【Abstract】 The Earth’s principal moments of inertia are the geodetic and astronomical fundamental Earth parameters. The paper is devoted to the Earth’s principal moments of inertia and the related issues. Section 1 formulates the Earth’s principal moments of inertia and the Earth’s flattening; Section 2 deals with the computation of the second-degree harmonic coefficients in the principal axes coordinate system; Section 3 studies the directions of the Earth’s principal axes of inertia, and Section 4 presen... 更多还原
