Abstract
The design of an optimized retroreflector array for satellite laser ranging (SLR) is critical for enhancing satellite tracking accuracy and providing a passive space segment backup for conventional attitude determination systems. This thesis documents the research aimed at developing an effective retroreflector array for the new TU Delft platforms: Delfi-Twin and the Da Vinci satellite. The goal is to enable SLR measurements via both the International Laser Ranging Service (ILRS) network and the laser communication terminal at Delft University. Following a structured approach, the most suitable array configurations were identified through a Probability of Visibility (PoV) simulation. Consequently, a link budget analysis was performed, coupling the selected arrays with the considered ground stations to define the required retroreflector size to enable SLR measurements. Improvements to the Delft laser communication terminal have also been proposed to enhance its SLR capabilities. Future work will focus on qualifying the acquired retroreflectors and finalising the holder structure for satellite integration.
