Coordinates of features on the Galilean satellites

Merton E. Davies, Frank Y. Katayama

Published 1980

Control nets of the four Galilean satellites have been established photogrammetrically from pictures taken by the two Voyager spacecraft during their flybys of Jupiter in 1979. Coordinates of 504 points on Io, 112 points on Europa, 1,547 points on Ganymede, and 439 points on Callisto are listed. Selected points are identified on USGS maps of the satellites. Measurements of these points were made on 234 pictures of Io, 115 pictures of Europa, 282 pictures of Ganymede, and 200 pictures of Callisto. The systems of longitude were defined by craters on Europa, Ganymede, and Callisto. Preliminary solutions have been found for the directions of the axes of rotation of the Galilean satellites. New mean radii have been determined as 1,815 plus or minus 5 km for Io, 1,569 plus or minus 10 km for Europa, 2,631 plus or minus 10 km for Ganymede, and 2,400 plus or minus 10 km for Callisto.
