139 CCD images of the Uranian satellite system taken with the Jacobus Kapteyn Telescope in 1990 and 1991 have been calibrated astrometrically with two WFC photographic plates taken on the same telescope in 1996. The numbers of images are: I Ariel 139; II Umbriel 132; III Titania 137; IV Oberon 128; V Miranda 117; total 653. The root-mean-square (rms) fits of the inter-satellite positions to the numerical integration by Taylor (1998) lie between and , depending on which two satellites are compared.
