First results on the development of the coordinate systems and control networks of the Galilean satellites of Jupiter. Pictures of the four satellites were taken as the two Voyager spacecraft approached Jupiter during March and July 1979, and nearly full coverage of the satellites was obtained by each flyby as the satellites rotated in front of the cameras. High-resolution mosaics of the satellite surfaces were obtained during closest encounter. Control nets of the Galilean satellites have been computed photogrammetrically and mean radii measured. The pictures in the control nets are identified, the coordinates of the control points are given, and identifications of some of the control points are shown on figures. Improved results will emerge as more data are incorporated in the computations.
