In this paper, we present astrometric results derived from reduction of 65 lightcurves made in 1995-1996 during the PHESAT95 campaign of observation of Saturnian satellites mutual events. These results have an accuracy of about 20-30 mas and are compared to those obtained by Emelianov et al. (1997) for the 3 events observed in Crimea and Kazakhstan. We also discuss the reliability of the method used for reducing the lightcurves from the mutual events of 1980.
