Abstract
We propose a cooperative observational project of using the photo-electric astrolabe Mark I of Shaanxi Observatory in Irkutsk. As the instrument will be equipped with a Z = 45° angle prism, it will have no blind zone when used at latitude ( φ = 52°. Important contribution can be expected to the establishing of fundamental reference system and the maintenance of the Hipparcos Catalogue system.
