Satellite ephemerides played an important role in the navigation of the Voyager 1 and 2 Saturn encounters. They were used in the models of the gravitational forces acting on the spacecraft and of the onboard optical navigation measurements. They also were used in predicting the pointing directions of the onboard instruments for satellite scientific observations. This paper describes the form of the Voyager Saturn satellite ephemerides and gives the values of the parameters used in the ephemeris generation. The update of those parameters as part of the optical navigation process is also discussed, and the best Voyager ephemerides are presented and compared to those based on earlier Saturn satellite theories.
