In this paper, we publish measurements of 1514 positions of the major satellites
of Saturn made in 1995 and 1997 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 in 1995 and
in 1997.
Key words: satellites of Saturn / astrometry
