Catalog of 1385 astrometric positions of the Saturn’s moons (S2-S9) was obtained with Tycho-2 as reference frame on the basis of photographic observations carried out in MAO NAS of Ukraine during 1961-1990. The digitizing of photographic negatives was done using Epson Expression 10000XL (ЕЕ) commercial scanner in a gray scale 16 bits with the resolution 1200 dpi. The reduction was carried out in the LINUX-MIDAS-ROMAFOT software supplemented with additional modules. The internal positional accuracy of the reduction is 0.09…0.23 arcsec for both coordinates, the photometric one is 0.27…0.37 mag for photographic magnitudes of Tycho-2 catalog. The calculated topocentric positions of moons were compared with the ephemeris data DE405+ TASS1,7 from IMCCE in on-line mode. For the most moons, the differential coordinates “satellite minus satellite” were derived from the comparison with theoretical data (http://lnfm1.sai.msu.ru/neb/nss/nssep hmr.htm).
