Atmospheric drag on artificial satellites

By using observed values of dP/dt and a convenient model to represent the variable density (ρ) and the scale height (H) of the atmosphere, we calculate mean values for the effective cross-section (S) of a non-spherical satellite at every day during a period of about two and half months. For that cal...
