Scientific paper

The new polyvalent astrolabe of the Paris Observatory is described. After some optical modifications this new instrument is able to observe the stars, some planets, and the sun with an internal error less than 0.4 arcsec in the last case. Some new modifications are in progress to obtain better results and stability in the solar observations. This instrument will be able to give a valuable contribution in the solar system studies and in the comparisons of some celestial reference systems, particularly durint the Hipparcos satellite mission.
