Dynamic Scene 3D Reconstruction of an Uncooperative Resident Space Object
Bala Prenith Reddy Gopu, Timothy Jacob Huber, George M. Nehma +5
Characterization of uncooperative Resident Space Objects (RSO) play a crucial role in On-Orbit Servicing (OOS) and Active Debris Removal (ADR) missions to assess the geometry and m…
Real-time Testing of Satellite Attitude Control With a Reaction Wheel Hardware-In-the-Loop Platform
Morokot Sakal, George Nehma, Camilo Riano-Rios +1
We propose the Hardware-in-the-Loop (HIL) test of an adaptive satellite attitude control system with reaction wheel health estimation capabilities. Previous simulations and Softwar…
Adaptive Controller For Simultaneous Spacecraft Attitude Tracking And Reaction Wheel Fault Detection
Camilo Riano-Rios, George Nehma, Madhur Tiwari
The attitude control of a spacecraft is integral to achieving mission success. However, failures in actuators such as reaction wheels are detrimental and can often lead to an early…
End-to-End Imitation Learning for Optimal Asteroid Proximity Operations
Patrick Quinn, George Nehma, Madhur Tiwari
Controlling spacecraft near asteroids in deep space comes with many challenges. The delays involved necessitate heavy usage of limited onboard computation resources while fuel effi…
