Description
Space weather can adversely affect the operation of satellites in Earth orbit and consequently exacerbate the problem of debris generation in space. The associated effects are more probable around the peak of a solar cycle. As we approach the peak of the 25th solar cycle, we leverage on our institute’s cross-program capabilities in model-driven assessment and prediction of LEO objects’ aerodynamic drag, to investigate the deleterious impact of space weather-enhanced atmospheric drag. In this work, we performed detailed analysis of long- and short-term drag impact on selected [catalogued] LEO objects and thus provide space situational awareness (SSA) in the current solar cycle regime. We also predict their rate of orbit decay ahead of the solar cycle peak using a novel ephemeris data-assisted calibration (EDAC) simulation approach and subsequently support the outcome with data obtained in the post prediction regime.
