Data Update Schedule
All data is sourced from the U.S. Space Force 18th Space Defense Squadron and synchronized on the following schedule (UTC).
Source updates 2-3x/day. Positions are computed on-demand via SGP4 propagation.
Conjunction screenings run every ~8 hours. 30-min offset accounts for processing lag.
Catalog metadata: names, object type, country, launch/decay dates.
