Astronomers who study the dynamics of the satellites of Saturn benefit greatly from the catalogue of historical observations compiled by [Str90] which contains almost all astrometric observations of the eight major satellites made between 1874 and 1989. However, it cannot be emphasised strongly enough that new observations must be made at every available opportunity in order to maintain the ability of current orbital models (both analytical theories and numerical integrations) to predict the positions of the satellites accurately. The need for accurate predictions has been highlighted by the forthcoming NASA/ESA mission "Casini-Huyghens".
With this need in mind, we have embarked on a long-term programme of astrometry of the major satellites using a CCD detector on the 1-metre Jacobus Kapteyn telescope (JKT) on the island of La Palma (Canaries). At the present time, we have undertaken three observing campaigns, at the oppositions of 1991, 1993 and 1994. On each occasion, we were allocated seven consecutive nights during "bright time" i.e. around the time of the full moon closest to the date of opposition of Saturn.
