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

Abstract In 2012 the UN Security Council and the European Union bolstered US economic sanctions on Iran, disembedding the country's economy from financial markets. Since then, the sanctions have radically devalued Iran's currency, leading Iranians to seek a viable standard of value elsewhere. They have done so through ghachagh (fugitive) configurations
