Descripció:
In-orbit servicing in geostationary orbit (GEO) requires highly reliable guidance, navigation, and control (GNC) solutions, with vision-based relative navigation playing a central role in safe rendezvous and proximity operations. This thesis focuses on the development, optimization, and assessment of image-based relative navigation algorithms within an end-to end rendezvous simulation framework, supporting the design and validation of Infinite Orbits’ GEO servicer missions Endurance and OG3. The work will use and extend a MATLAB/Simulink-based image generation environment and rendezvous simulator to study the performance, robustness, and limitations of autonomous vision-based navigation along representative GEO rendezvous trajectories.
Objectius:
Understand the principles of vision-based relative navigation and its application to GEO rendezvous and inspection missions.
Optimize and extend an existing MATLAB/Simulink-based image generation and simulation framework for rendezvous scenarios, including realistic camera models and target geometries.
Test and assess far-range relative navigation algorithms using synthetic images, lab-acquired images, and available space imagery, with emphasis on robustness to noise, illumination, and geometry variations.
Evaluate the performance of multiple GNC/relative navigation algorithms via Monte Carlo campaigns over representative rendezvous trajectories.
Contribute to an integrated end-to-end rendezvous simulator and develop performance metrics and visualization tools for navigation accuracy, robustness, and computational efficiency.
Tasques a realitzar / Característiques:
● Perform a literature review on vision-based relative navigation for spacecraft rendezvous in GEO and related GNC techniques.
● Study the underlying orbital mechanics and relative motion models relevant for GEO rendezvous, as well as the basics of camera modeling and image-based measurement generation.
● Become familiar with the company’s MATLAB/Simulink-based image generation tools, rendezvous simulators, and associated scripts used by the Rendezvous team.
● Design and implement optimizations and extensions to the image generation software (e.g., rendering performance, sensor and optics models, scenario configuration), ensuring compatibility with existing tools.
● Configure and execute test campaigns where far-range relative navigation algorithms are run in the loop with the image generator, using simulated rendezvous trajectories, lab-based images, and real space imagery when available.
