6 Conclusions

For the first time the major satellites of Saturn were observed by observatories in Russia and Kazakhstan within a framework of a coordinated observing campaign. This has been for us the first work of this type. Wide experience has been gained in performing such observations and reduction of their results. The main results of this work are a number of photometry sets of three mutual events of Saturnian satellites. Preliminary reduction of these observations [12, (Emel'yanov et al. 1997]) showed that they can be used to infer relative astrometric coordinates of satellites with an accuracy from $0\hbox{$.\!\!^{\prime\prime}$}002$ to $0\hbox{$.\!\!^{\prime\prime}$}03$.Photoelectric and CCD photometry yielded positional data of approximately the same accuracy.

Another result of the observing campaign are CCD measurements of positions of the major Saturnian satellites. A total of more than 1500 relative coordinates of satellites were obtained. The accuracy of position observations, as inferred from repeatability of measurements, varies from $0\hbox{$.\!\!^{\prime\prime}$}05$ to $0\hbox{$.\!\!^{\prime\prime}$}3$. We also performed photographic observations to determine a total of 237 relative positions of Saturnian satellites.
