Origin of the International Terrestrial Reference Frame

Journal of Geophysical Research: Solid Earth, 2003
With recent improvements in space geodesy, the Earth's center of mass (CM) and center of figure (CF) are no longer indistinguishable. The current origin of the International Terrestrial Reference Frame (ITRF) is defined as the CM, which shows measured seasonal variations of several millimeters to 1 cm with respect to true CM.

A sequential estimation approach to terrestrial reference frame determination

Advances in Space Research, 2020
Abstract We review the main concepts underlying the determination of terrestrial reference frames (TRFs) through a recursive algorithm based on Kalman Filtering and Rauch-Tung-Striebel (RTS) smoothing which is currently adopted at Jet Propulsion Laboratory (JPL) to compute sub-secular frame products (JTRFs).
