Abstract: Astrometric positions of Saturn's satellites were obtained during 1981 and 1982 as part of a program of observations at the Bordeaux Observatory, France. Approximately 170 plate exposures were taken with the 38-cm refracting telescope which has a focal length of about 7 m and a plate scale of 30.120 arcsec/mm. The observational results were reduced by means of the AGK3 and SAO reference stars. The positions of Saturn's satellites are presented in the astrometric topocentric coordinate system and in intersatellite relative coordinates. Intersatellite relative positions were computed on the basis of the theoretical results of Rapaport (1977) and are compared with the observed positions. The comparison revealed a r.m.s. error for the computed intersatellite relative positions of 0.20 arcsec. The complete observational data for the satellite positions are given in a table.
