# NAIF reconstructed trajectories (SPK kernels) for flyby spacecraft

Reconstructed trajectories are fitted solutions, not tracking data; they include whatever the navigators modelled and cannot by themselves show an anomaly. The Galileo SPKs begin in 1995 and miss both Earth flybys. Useful for geometry (declinations, perigee latitude) and for checking the published parameters.
