Modeling and Analysis of a Thermospheric Density Measurement System Based on Torque Estimation
… and analyzes an in-situ method for measuring the density of the thermosphere at low Earth orbit (LEO) altitudes in real time. As satellites orbit in the thermosphere, the sparse yet present air perturbs their orbits via the drag force. The drag force is poorly characterized and has a significant …

Satellite Drag and Sustainable Space Operations in a Dynamic Thermosphere
… behavior directly without reconstructing thermospheric mass density or requiring detailed knowledge of satellite properties such as the ballistic coefficient. This end-to-end strategy offers substantial computational and operational advantages for many space domain awareness tasks. …

Density Model Corrections Derived from Orbit Data to Characterize Upper Atmospheric Density Variations
One goal of this research is to estimate density model corrections using readily available Satellite Laser Ranging (SLR) data, and to demonstrate this approach's validity for additional satellites with similar data sets in the future. The research also aims to utilize previously unused or little …
