<abstract>
<p>A new global control point network was derived for Enceladus, based on Cassini and Voyager-2 image data. Cassini images were
taken from 2005 to 2014, for Voyager we have only one flyby in the middle of 1981. We have derived 3D Cartesian coordinates for
1128 control points as well as improved pointing data for 12 Voyager and 193 Cassini images in the Enceladus-fixed coordinate
system. The point accuracies vary from 55 m to 2900 m (average point accuracy &amp;ndash; 221 m). From tracking of the control points we
detect a librational motion described by a model which includes 3 different periods and amplitudes (Rambaux et al., 2011). We
determine the amplitudes for each term. Our new control point network has a higher number of point measurements and a higher
accuracy than previous data (Giese et al., 2014).</p>
