The Photoelectric Astrolabe Mark I (PHA I) has been revised with a new combined
prism which could work as an almucantar with zenith distance of ,to measure continuous declinations at the latitude of Irkutsk, Russia
(
). The
PHA I has been working at the astronomical base of VS NIIFTRI in Irkutsk since
Nov. 1995 based on an international cooperation agreement of near 4 years for
star catalogue and EOP measurements. The first observing program was ended in
June 1997, giving corrections in both right ascension and declination to 200
stars with no blind zone in declination determination, which most astrolabe
catalogues in the world usually would have
.
Key words: astrolabe -- star catalogue
