Saved queries into the catalog.
Each showcase runs against the database, fused from CelesTrak, GCAT, Wikidata and SatNOGS DB, with provenance where available and explicit unknowns.
Active satellites by operator
Every operator in the catalogue, ranked by how many active payloads it currently has in orbit.
Largest Active Constellations
Top operators ranked by number of active payloads in orbit. Operator names are sourced from GCAT where available, falling back to CelesTrak.
EU Earth Observation Satellites
Active payloads from ESA member states, filtered by country code and non-decayed status. Excludes debris and rocket bodies. Sorted by most recently catalogued.
Recent Reentries
Payloads marked DECAYED in the CelesTrak catalog, sorted by decay date from GCAT where available. Rocket bodies and debris are not yet tracked as individual records; see Known limitations on the Methodology page.
Launched, Never Operational
Payloads that reached orbit (confirmed launch date from GCAT) but were never recorded as operational, still in orbit, never switched on. A cross-source join between CelesTrak's orbital catalog and GCAT's launch records.
