Astrometric positions of the five largest Uranian satellites from
750 CCD frames taken at the oppositions of 1995 through 1998 are
presented. The images were obtained over 35 nights. Observed positions are
compared with the calculated positions from GUST86. The standard deviations
are better than 
for the four largest satellites and
for Miranda.
