In this paper, we publish 1206 measurements of positions of the major satellites of Saturn made in 1990, 1991, 1993 and 1994 using CCD detectors attached to the 1-metre Jacobus Kapteyn Telescope on the island of La Palma. Analysis of the data as inter-satellite positions shows that the observations of Tethys, Dione, Rhea and Titan have root-mean-square residuals of 0.″08, corresponding to 500 km at the distance of Saturn.
Key words: satellites of saturn / astrometry
