Research Interest:

This dissertation addresses the challenge of autonomous spacecraft rendezvous and docking through advanced trajectory optimisation and control strategies. The study initially applies the Clohessy-Wiltshire equations and Hohmann transfer manoeuvres to develop theoretical trajectories, analysing their precision and feasibility in simulated low Earth orbit (LEO) scenarios. By incorporating realistic simulations, the research assesses trajectory accuracy against actual space conditions, highlighting the limitations of traditional methods when extending beyond specific orbital distances. To enhance trajectory design and docking precision, Genetic Algorithms (GA) and Particle Swarm Optimization (PSO) are integrated, emphasising the impact of varied crossover and selection methods on solution efficacy. These optimisation tools are tested in their ability to refine trajectory calculations, reducing potential errors during the final approach and docking stages. The research juxtaposes these modern optimisation techniques against conventional approaches, demonstrating significant improvements in trajectory planning and execution. Key outcomes include the successful demonstration of transition from Hohmann transfers to final rendezvous stages, albeit with noted risks associated with system failures post-initial thrust. The study's findings advance the practical application of trajectory optimisation in mission design, potentially influencing future strategies for satellite operations and space exploration.
