Abstract

Present day space geodetic techniques (VLBI, SLR, GPS) lead to the definition of
terrestrial reference systems with greater precision than classical techniques which
were employed in the definition of the conventional international origin (CIO). The
importance of the CIO is justified by its adoption not only for the successive
alignments of several ITRFs, through the BIH pole, but also for the definition of the
global geodetic reference system of 1980 (GRS 80). This is the motivation for
defining a new conventional international reference origin (CIRO) and for the need
to adopt a new global geodetic reference system, based on space geodetic
techniques, by the appropriate international organizations.
