Reduced-Order Data Assimilation for Thermospheric Density Using Physics-informed SINDyc Models
Sriram Narayanan, Daniele Sicoli, Piyush Mehta
Orbit prediction and space situational awareness require accurate thermospheric mass density, which responds nonlinearly to solar and geomagnetic forcing across several orders of m…
