ORBIT CENSUS

MISSION CENSUS

Active satellite breakdown by mission purpose, operator type, and industry sector. Hover any category label for a short definition.

OPERATOR CONCENTRATION

Who controls orbital space — top operators by active satellite count, market concentration (HHI), and country-level dominance.

DECAY INTELLIGENCE

Orbital decay intelligence — recently reentered objects, satellites past design lifetime, historical decay trends, and predicted reentries from orbital element analysis.

PREDICTED REENTRIES

Linear trend projection based on perigee altitude regression. Not a physical atmospheric model — does not account for solar activity, atmospheric density variations, or satellite maneuvers. Use for screening and relative prioritization, not authoritative reentry prediction. Predictions require 3+ orbital snapshots per object.

ASSET LIFECYCLE

Satellites that have reached end of operational life — total loss, degraded performance, graveyard disposal, or at imminent decay risk. These categories track satellite operational fate across the active fleet.
