Classical Element Feedback Control for Spacecraft Orbital Maneuvers
The recent addition of autonomous formation flying spacecraft to the world's satellite fleet provides new motivation to study feedback control techniques. In this thesis, we develop nonlinear orbit control laws for use in spacecraft orbital maneuvers, and spacecraft formation flying. We apply these …

Closed-loop control of spacecraft formations with applications on SPHERES
Formation flying satellites offer potentially greater science returns and operational capabilities than attainable with a monolithic spacecraft. Successful control of a formation of spacecraft can be divided into two separate stages. The first stage creates a plan that meets a set of mission …

Dynamics and control of electromagnetic satellite formations
Satellite formation flying is an enabling technology for many space missions, especially for space-based telescopes. Usually there is a tight formation-keeping requirement that may need constant expenditure of fuel or at least fuel is required for formation reconfiguration. Electromagnetic …

Management and Analysis of Localization Information in Uncrewed Aerial Systems
… improves the timeliness of localization-information exchange, enabling tighter formation keeping, faster synchronization, and overall behavior more consistent with the low-latency, high-reliability goals of URLLC-class services. Finally, we develop a localization-driven trajectory …
