The latest estimation of Jupiter's gravitational field was obtained by processing the Doppler data from two gravity orbits of NASA's Juno mission, using the Jet Propulsion Laboratory software MONTE. In this work, we present the results of the analysis of the same measurements employing the orbit determination software ORBIT14, developed at the University of Pisa, used here for the first time with real data. We found that the estimated values of Jupiter's spherical harmonic coefficients from the two solutions are consistent within the formal uncertainty. The analysis is complemented with a discussion on the results obtained with alternative set-ups.

Abstract
The latest estimation of Jupiter's gravitational field was obtained by processing the Doppler data from two gravity orbits of NASA's Juno mission, using the Jet Propulsion Laboratory software MONTE. In this work, we present the results of the analysis of the same measurements employing the orbit determination software ORBIT14, developed at the University of Pisa, used here for the first time with real data. We found that the estimated values of Jupiter's spherical harmonic coefficients from the two solutions are consistent within the formal uncertainty. The analysis is complemented with a discussion on the results obtained with alternative set-ups.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
