UPGRADE AND TESTING OF THE NEXT GENERATION FLOATING SPACECRAFT SIMULATOR

Abstract

On-orbit servicing (OOS) is critical for extending the operational lifespan and functionality of a spacecraft. To support the development of OOS technologies, it is essential to build ground-based experimental platforms that emulate the complexities of space. This thesis presents the design and implementation of a laboratory-based OOS testbed by using a floating spacecraft simulator (FSS) equipped with a seven-degree-of-freedom robotic manipulator. Upgrading a previously built FSS was carried out to modernize the hardware and integrate a modular software architecture. The updated platform is intended to enable precise control, low-friction mobility, and high-dexterity manipulation, all key characteristics needed to simulate realistic maintenance tasks. Experimental procedures were developed and conducted to validate the system functionality and demonstrate the feasibility of laboratory-based OOS testing. The results establish a foundation for future research in autonomous robotic servicing and contribute to advancing the readiness of OOS technologies for operational deployment in space missions.
