At the Engelhardt Astronomical Observatory (EAO), we observed photographic positions of 113 Galactic Radio Sources (GRS) in the system PPM catalogue (Rizvanov & Dautov, 1998, Kinematics and physics celestial bodies, 5, 457). Analysis of their accuracy is made by comparison with the Hipparcos catalogue (Perryman et al., 1997, Vat. ) and astrometric catalogue of radio stars in the radio window from the article of Walter et al. (1990A&AS...86..357W).
