# OrbitCompute.ai + OrbitCompute.com — Full OCEI v2.0 Standard, Thermodynamic, Radiation & Token-Economic Specification (v15.0)

## 1. OCEI v2.0 (Orbital Compute Efficiency Index) — Formal 4-Pillar Methodology
- Publisher: OrbitCompute.ai // Spatial Compute Holdings (https://orbitcompute.ai/ocei)
- Scale: 0.0 to 1,000.0 points across four equi-weighted 250-point physical pillars, updated dynamically every 300 seconds from 6 live NOAA SWPC & GOES satellite streams.
- Multi-Regime Live Scores: 650 km Dawn-Dusk SSO = 972.1/1000 (+442.1 bps) | 550 km Inclined LEO = 867.8/1000 | 1,500 km MEO = 863.8/1000 | Terrestrial Tier-IV Grid Baseline = 530/1000.
