CelesTrak publishes two-line orbital elements for the ISS and thousands of satellites, from which passes over an observer can be computed by SGP4 propagation. The source and pipeline are modelled here as architecture-ready; neither the live feed nor the propagation is wired, and no pass time is fabricated.
