Abstract

Analyzing the Hipparcos proper-motion system compared the FK5 and SPM 2.0 systems, the inertiality of the Hipparcos system has been studied and a large remaining rotation of its proper-motion system has been hinted.

Key words	astrometry － reference system － catalogue － proper-motion system
