Abstract. The Astronomical Observatory in Belgrade possessed the three classical instruments for fundamental astrometry with which the positions of stars and other celestial bodies were determined. From 1960, when the instruments were mounted to be followed by the first examinations and test observations afterwards, till 1995, when the observations ceased, eight observational star catalogues were finished, regular measurements for the Sun and internal planets followed the star observations and based on these observational catalogues two general catalogues of star positions were compiled. In this the most numerous and most valuable results were obtained with the Belgrade Meridian Circle.
