Astrometric positions of the first eight largest Saturnian
satellites and the Lagrangian satellites Helene, Telesto
and Calypso are presented from 493 CCD frames taken at
the oppositions in 1995 through 1999. The images were
obtained over 27 nights. Observed positions are compared
with the calculated ones from Vienne and Duriez TASS 1.7
for the large satellites and from JPL positions for the
Lagrangian satellites. The rms is about 0
12 for the
former but 020 for Iapetus and 028 for Hyperion.
For the Lagrangian satellites it is about 021 for
Helene, 202 for Telesto and 060 for Calypso.
Key words: planets and satellites: individual: Saturn / astrometry
