Advanced ensemble modeling method for space object state prediction accounting for uncertainty in atmospheric density
Smriti Nandan Paul, Richard J. Licata, Piyush M. Mehta
For objects in the low Earth orbit region, uncertainty in atmospheric density estimation is an important source of orbit prediction error, which is critical for space situational a…
Stochastic modeling of physical drag coefficient -- its impact on orbit prediction and space traffic management
Smriti Nandan Paul, Phillip Logan Sheridan, Richard J. Licata +1
Ambitious satellite constellation projects by commercial entities and the ease of access to space in recent times have led to a dramatic proliferation of low-Earth space traffic. I…
Understanding variability in HASDM to support space traffic management
W. Kent Tobiska, Marcin D. Pilinski, Shaylah Mutschler +5
With more commercial constellations planned, the number of Low Earth Orbit (LEO) objects is set to TRIPLE in two years. The growth in LEO objects directly increases the probability…
The current state and future directions of modeling thermosphere density enhancements during extreme magnetic storms
Denny M. Oliveira, Eftyhia Zesta, Piyush M. Mehta +4
Satellites, crewed spacecraft and stations in low-Earth orbit (LEO) are very sensitive to atmospheric drag. A satellite's lifetime and orbital tracking become increasingly inaccura…
Benchmarking Forecasting Models for Space Weather Drivers
Richard J. Licata, W. Kent Tobiska, Piyush M. Mehta
Space weather indices are commonly used to drive operational forecasts of various geospace systems, including the thermosphere for mass density and satellite drag. The drivers serv…
A quasi-physical dynamic reduced order model for thermospheric mass density via Hermitian Space Dynamic Mode Decomposition
Piyush M. Mehta, Richard Linares, Eric K. Sutton
Thermospheric mass density is a major driver of satellite drag, the largest source of uncertainty in accurately predicting the orbit of satellites in low Earth orbit (LEO) pertinen…
