Positions of Uranian satellites from 333 photographic plates obtained at the Cassegrain focus of a 1.6 m reflector are given for the oppositions of 1983 through 1988. These positions were reduced using photometric methods and compared with those calculated theoretically calculated from GUST86. The observed minus calculated residuals referred to Oberon, have standard deviations of the order of 0".04 for the four greatest Uranian satellites and 0".09 for Miranda. These residuals for the four satellites are better than the most precise found in the literature.
