Terms
Terms of use
Short, because the situation is simple: this is a free informational reference built from public catalogs, offered without warranty.
1
Informational platform
Positions are propagated with SGP4 from published element sets and degrade with the age of those elements; statuses, owners and launch data follow the upstream catalogs with their own latency; classifications such as orbit class, mission type and constellation membership are derived by documented rules and can be wrong for individual objects. Freshness and provenance are displayed on every page so you can judge each value yourself.
2
No warranty, limitation of liability
The site and its API are provided as is and as available, without warranty of any kind, express or implied, including accuracy, completeness, fitness for a particular purpose or uninterrupted availability. To the fullest extent permitted by law, Simon-Pierre Boucher accepts no liability for any loss or damage arising from the use of, or reliance on, the information published here.
3
Sources and attribution
SatelliteIndex aggregates public and licensed orbital, governmental, scientific, and operator data from multiple sources. Orbital data courtesy of CelesTrak. Derived classifications (constellation membership, orbit class, mission type) follow the published methodology.
Upstream data remains subject to the terms of its publishers, listed with each source on /sources. If you reuse data obtained from SatelliteIndex, keep those attributions — in particular “Orbital data courtesy of CelesTrak” — and link back to this site for derived values.
4
Acceptable use of the API
The public API is free during the MVP phase and rate-limited per client (limits on /developers). Do not attempt to bypass rate limits, scrape the HTML pages in bulk when the API provides the same data, or access the private /admin area. Abusive clients may be blocked without notice.
5
Changes and contact
These terms may change as the platform evolves (for example when API keys or paid tiers are introduced); the current version is always the one published at this address. Questions: contact@spboucher.ai. See also the privacy page.
