LSP-Orbital v4.5: Lo-Shu Geometric Projection with Real BSTAR Drag Coefficients for LEO Debris Trajectory Correction

LSP-Orbital v4.5 extends the Lo-Shu Geometric Projection (LSP) framework for Keplerian orbit propagation error correction in low Earth orbit (LEO). Key advancement: integration of real BSTAR ballistic drag coefficients from Space-Track.org. A Soft-Blending Gate (sigmoid interpolation) eliminates prediction discontinuities at the 30-minute time-stratification boundary. Results (N=640 LEO held-out): 69% win rate over Keplerian, 28.3% mean error reduction, dt=30 min boundary win rate +13 percentage points (65% to 78%), failure rate 19.4% to 18.9%.
