Abstract:
Simulated radio tracking data from one flyby of Europa, two flybys of Ganymede, and two flybys of Callisto by the Galileo Orbiter yield estimates of the standard errors in the gravitational coefficient J*** of 44, 8.5, and 12 (in units of 10***) for Europa, Ganymede, and Callisto, respectively; errors in C***(in units of 10***) are 12, 1.7 and 2.1.
