List GEO slots in the Clarke registry (curated positions merged with UCS-derived positions). The default is a compact page of 50: slug, label, longitude, region, operatorIdentity (split, single, or none), country, status, and satCount. Pass offset to continue. view=full returns occupancy observations (tleEpoch and tleStale, older than 45 days when a TLE supplied occupancy), operatorMix, FCC rows, disputes, and source vintage, in pages of 10 (max 25). all=true is the explicit full list for that view and is large when view is full. The human Terminal models are not in either view. ITU filings are not in this product. ITU Space Explorer is the current ITU source. SNS Online shut down in January 2025 (ituRecorded is not_in_product on the full record). TLE longitude is a tracked position, not an FCC or ITU assignment.
