Trajectory record

Time-dependent navigation trajectory

Source states place the model at the selected time. Reconstructed flight, estimates, predictions and historical mission plans are identified by interval; gaps remain visible.

Source records and sampling assumptions are retained with the repository data. Model attitude and surface appearance are illustrative.
