Published purpose

The objective of this research is to develop an atmospheric drag model that incorporates the effects of solar activity, atmospheric density, satellite altitude and geomagnetic activity. Atmospheric drag effects cause large and unpredictable uncertainties in orbit determination/prediction, particularly during periods of highly active space weather. By analyzing and modeling the atmospheric drag forces acting on the CASSIOPE satellite, the researchers seek to understand the temporal and spatial variability of these forces and their effects on satellite orbit, altitude decay and lifetime. These findings will contribute to a better understanding of the dynamics of the Earth's atmosphere and its impact on space-based assets.
