title = "Drag coefficient estimation using satellite attitude and orbit data",
abstract = "Current spacecraft decay models assume a constant value of 2.2 for the coefficient of drag. This assumption is driven by the difficulty in accurately modeling the spacecraft's cross-sectional area exposed to the direction of motion. This research discards the assumption of a constant coefficient of drag; instead, it uses attitude data from the Swift spacecraft to determine the cross-sectional area and directly calculates the coefficient of drag over the nine years of orbital data. This method partially validates the NRLMSISE-00 atmospheric model and encourages a new examination of the coefficient of drag value used to determine the decay of spacecraft orbits.",
