摘要：We have re-measured control points and re-computed a control point network for Saturn's satellite Dione. Our networkis based on16 images (obtained by the narrow-angle cameras of Voyager I and II), 135 control points, and 741 pointmeasurements. We obtained mean point accuracies of 1.8 km, 2.9 km, and 1.2 km for X, Y, and Z, respectively. Theradius of Dione was re-determined to be 562.5 km +/- 0.2 km with a RMS deviation of 3 km, consistent with 560 km(RMS: 5 km) found by Davies et al. 1983. Subsequently, we generated a sequence of controlled digital base mosaicsfor the five (among the largest) satellites Mimas, Enceladus, Tethys, Dione, and Rhea. The images are reprojected inMercator and Polar Stereographic projections using satellite shape parameters, as recommended by IAU. On the basisof these mosaics, maps in printable format have been produced. Our data products update previous control pointnetworks and maps of these satellites, released by the RAND Corporation and the USGS (United States GeologicalSurvey), respectively, between 1982 and 1992. Our maps constitute an important basis for the planning of the Cassinimission, which will begin its orbital tour through the Saturnian system in June 2004 (http://saturn.jpl.nasa.gov
