Systematic errors of the catalog obtained with the observation of Photoelectic Astrolabe Mark I (PHA I) of Shaanxi Astronomical Observatory, mounted at Irkutsk, Russia, are analyzed with reference to the Hipparcos catalog. It is shown that the systematic errors of the astrolabe catalog can be removed effectively using the Hipparcos Catalog as reference and that a star position system with high precision can be obtained.

Key words: astrometry -- reference system
