The Hipparcos (H) reference system will contain 100 000 stars whose positions and proper motions will be known with an accuracy of 0″.002 and 0″.002/yr respectively. Because a residual rotation of the H system may exist and because a VLBI extragalactic frame is being constructed one must (i) determine an eventual rotation of the H rigid frame, (ii) link the H system to the VLBI extragalactic frame. VLBI observations at JPL (Fanselow et al., 1981) have provided a catalogue of about 100 quasars with internal accuracy of' ~ 0″.001.
