The gravity science experiment on Dawn (also known as the Radio Science experiment) used the communications system in concert with the optical imaging system to accurately track the spacecraft's motions as it orbits the asteroids and use these motions to map the gravity field. The objectives of the Dawn gravity science experiment were to determine the masses, global gravity fields to the 12th harmonic degree and order, the principal axes, the rotational axis, and the moments of inertia of Ceres and Vesta.

This bundle contains raw radio data that can be used to determine the position
              and velocity of the DAWN spacecraft during its encounter with 1 Ceres.  
              The bundle also contains the calibration data for the effects of Earth's ionosphere
              and troposphere, meteorological conditions at stations of the NASA Deep Space
              Network, thruster activity, spacecraft mass history, and changes in spacecraft 
              antenna selection. The data were used to determine the gravity field and shape of
              1 Ceres. Documents describing these data are also included in the bundle.
              The bundle is a migration of data from the original PDS3 archive.
