The newest general perturbations (SGP4) element set for every object in Earth orbit that the US Space Force publishes, as CCSDS Orbit Mean-Elements Message fields, with period, semi-major axis, perigee and apogee derived from them. Catalog numbers are full integers, so objects numbered 100000 and up are included.

Every launch in GCAT's launch list, one row per launch since 1942: orbital and deep-space launches with their international designation, plus missiles, sounding rockets and other suborbital flights. Each row has the date and time at the precision GCAT knows it, the vehicle, launch site, agency and outcome.

Every artificial object GCAT catalogs, one record per object since Sputnik in 1957: payloads, rocket stages, components and debris, including those that reentered, left for deep space or failed to reach orbit. Each record has the GCAT id, the US catalog number (six digits and up since the 2026 rollover), the international designator, owner, state, launch and decay dates, mass, status and the latest orbit with its class.
