Abstract:

Astrometric positions of the first eight Saturnian satellites obtained from 138 photographic plates taken in 30 nights in the years 1982 to 1988 are presented. All positions are compared with those calculated by the theory TASS1.7 (Vienne & Duriez 1998). The observed minus calculated residuals give rise to standard deviations smaller than 0$.\!\!^{\prime\prime}$3.

Key words: astrometry -- planets and satellites -- Saturn
