The Galileo spacecraft began its orbital tour of the Jovian system in December of 1995 and completed its eleven orbit prime mission in November of 1997 having had seventeen close encounters with the Galilean satellites. Earlier papers discussed the determination of the spacecraft orbit in support of mission operations from arrival at Jupiter through the first twelve orbits. In this paper we report on the reconstruction of the spacecraft trajectory for the entire prime mission, the development of a consistent set of ephemerides for the Galilean satellites, the improvement of the ephemeris of Jupiter, the determination of the gravity field of the Jovian system, and the determination of the orientation of the pole of Jupiter.
