The key to the understanding of our Solar System, how it originated and evolved, lies with the exploration of the miniature system of its largest planet, Jupiter. To this end, a number of space missions have been dedi- cated to probing the planet itself and its satellites, aiming at studying and comprehending the physical phenomena taking place within the system. In this context, a fundamental role is played by the determination of the gravity field of the bodies forming the system, by means of onboard radio science experiments. The main purpose of my research is to assess the accuracies attainable with the gravity measurements performed by NASA’s Juno and ESA’s JUICE missions, that will influence the comprehension of the interior structure and dynamics of the Jovian system bodies. In the frame of this dissertation I show how the precise reconstruction of the gravitational potential of Jupiter and its largest moons have the potential of improving our knowledge of the geodesy of the whole system
