The rapid increase in satellite launches has raised concerns regarding the sustainability of orbital operations, as defunct satellites and orbital debris pose significant risks to the safety and longevity of current and future space missions. Among proposed solutions, Net-Based Space Systems have emerged as a viable approach for Active Debris Removal. However, the stabilization of such systems after target capture remains a critical challenge, primarily due to the unknown and variable properties of the captured debris. Addressing these challenges necessitates the development of advanced control strategies and robust estimation techniques. This Thesis, conducted at the Space System Dynamics and Control Lab of The State University of New York at Buffalo, examines the dynamics and control of single-tethered and sub-tethered configurations for Net-Based Space Systems.
