CelesTrak Orbital Elements
CelesTrak publishes two-line orbital elements for thousands of satellites, from which passes over an observer can be computed by SGP4 propagation. Evaluated for Program CL and NOT connected: the host refused automated connections. The ISS is tracked instead from NASA's own operational ephemeris, which is a separate provider.

This is CelesTrak Orbital Elements's catalogue entry. The integration is planned: no fetch has been made, so no value, timestamp or provider response is shown — and none is invented.
What it provides
- ISS orbital elements (TLE)
- Satellite passes (via SGP4 propagation)
Limitations
Evaluated on 2026-08-29 and not connected: after a handful of requests the host began refusing connections at the TCP level, so no integration could be established and its terms could not be verified from this environment. That is the operator's prerogative; what it means here is that AsteriaStar makes no claim to CelesTrak data and does not scrape it. Tracking any satellite OTHER than the ISS waits on a licence-clear, reachable source of orbital elements; until there is one, no pass time for any other satellite is shown or fabricated.
