JPL ephemerides are discussed, with emphasis on what they represent and which aspects are well-determined. The determination of planetary ephemerides using spacecraft ranging data, radar ranging data, lunar laser ranging data, and optical transit data, is examined. Numerical estimates are presented, expected progress in the future is briefly considered, and possible uses for the ephemerides are discussed.
