Arc desirability	European Ku/Ka corridor (highest-revenue arc)	×1.80
Occupancy	3 co-located satellites	×1.36
Operator	Regional / other operator	×1.05
Spectrum	No band data (UCS-derived)	×1.00
Scarcity	Congestion score 48	×1.24

Heuristic estimate from public data, not a market quote. A baseline is multiplied by arc desirability, occupancy, operator tier, spectrum, and arc scarcity. See the methodology in docs.
