The Hipparcos Catalogue is used to form a homogeneous reference frame in which a new series of the Earth Orientation Parameters (EOP) is described. Being now linked to the extragalactic objects that define the new International Celestial Reference Frame (ICRF), it provides a new possibility of referring the long series of astrometric observations to the same reference frame that is used by the modern space techniques, such as Very Long-Baseline Interferometry. The observations of latitude and universal time variations (made in 1899.7-1992.0 and 1956.0-1992.0, respectively) at thirty observatories all over the world are used to determine the EOP in ICRF at five-day intervals. The results, covering almost one century, can further be used to study such fundamental phenomena as, e.g. precession-nutation, or interactions of the rotating Earth with geophysical excitations. In addition, certain improvement of some of the Hipparcos proper motions can also be obtained from our solution.
