Catalog data is the shared ephemeris available across Satcat Operations for screening and coordination. Three catalogs are published here. Each lists every file's NORAD ID, filename, designation, context, and usable time span, and each file can be exported.
Operator uploads are private by default. Sharing is controlled per organization in Control Center.
Every ephemeris uploaded to Satcat carries two metadata fields. Context states what the ephemeris represents operationally, and Designation states how it was produced. Together they determine how Satcat uses the data and what is shared with other operators.
Operators use Satcat Operations to upload ephemeris for their RSOs, enabling real-time conjunction screening, mitigation planning, and intent signaling. When shared with appropriate metadata, this operational data forms the foundation for high-confidence collision risk assessments and coordination with other operators.
Rules of the Road is Satcat's coordination protocol. It assigns maneuver responsibility for each conjunction and lets operators exchange mitigation intent asynchronously, without needing to reach each other directly.
