Data‐Driven Satellite Drag Modeling Without Dynamic Knowledge of the Atmosphere

Space Weather, Volume 24, Issue 2, February 2026.
Abstract Increasing congestion in low Earth orbit (LEO) from new satellite deployments and a growing debris population has made accurate orbital trajectory prediction essential for anticipating and avoiding potential collisions on a regular basis. Atmospheric drag is usually the dominant source of propagation error across much of LEO, especially during
