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.
SatelliteIndex.io is an informational platform. Orbital positions, predictions, conjunction information, reentry predictions, and derived metrics may contain delays or uncertainty and must not be used as the sole source for safety-critical, navigation, mission-control, military, or operational decisions.
