Loading contentCelesTrak 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.
Modelled from CelesTrak Orbital Elements. No live fetch has occurred in this build; the integration is planned.
Architecture-ready: the TLE source and an SGP4 propagation pipeline are modelled, but neither the live TLE feed nor the propagation is wired in this build. Satellite passes require a real TLE and an SGP4 implementation with clear licensing; until then, no pass time is shown or fabricated.

Two-line orbital elements (TLEs) for satellites including the ISS, used with a propagator to predict passes.
