  1. 1. Coordinate­Free Spacecraft Formation Control with Global Shape Convergence under Vision­Based Sensing

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Omid Mirzaeedodangeh; [2023]
    Nyckelord :Bispherical Coordinates; 3D Formation Control; Spacecraft Formation Flying; Multiagent Systems; Prescribed Performance Control; Vision-Based Sensing; Bisfäriska Koordinater; 3D Formationskontroll; Rymdfarkostformationsflygning; Multiagentsystem; Föreskriven Prestandakontroll; Synbaserad Avkänning;

    Sammanfattning : Formation control in multi-agent systems represents a groundbreaking intersection of various research fields with lots of emerging applications in various technologies. The realm of space exploration also can benefit significantly from formation control, facilitating a wide range of functions from astronomical observations, and climate monitoring to enhancing telecommunications, and on-orbit servicing and assembly.

  3. 2. Cooperative Navigation in Space in-proximity of Small Bodies

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Vignesh Kottayam Viswanathan; [2021]
    Nyckelord :Formation Flying; Asteroid exploration; stereovision;

    Sammanfattning : Autonomous proximity operations are the future of Deep space robotic exploration for searchof life, mining for resources and to establish outposts. Part of that future depends on howwell the spacecraft is capable to navigate around the complex environment of the smallcelestial body. LÄS MER

  4. 3. Thermomechanical Design and Analysis of the Lisa Phase Measurement System

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Pablo Martinez Cano; [2019]
    Nyckelord :LISA; PCB; temperature; passive; aluminum; aluminium;

    Sammanfattning : Gravitational Waves (GWs) are ripples in the curvature of spacetime that propagate as waves at the speed of light while travelling basically undisturbed from the moment of their creation by accelerated masses. GWs provide unique information about astrophysical sources, such as binary systems, allowing their exploration under a wide range of masses, mass ratios and physical states inaccessible otherwise and therefore opening a new window to observe the universe.

  5. 4. Constrained Low-Thrust Satellite Formation-Flying Using Relative Orbit Elements : Autonomous Guidance and Control for the NetSat Satellite Formation-Flying Mission

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Lukas Steindorf; [2017]
    Nyckelord :satellite; formation; control; guidance; continuous; low-thrust;

    Sammanfattning : This thesis proposes a continuous low-thrust guidance and control strategy for satellite formation-flying. Stabilizing feedback based on mean relative orbit elements and Lyapunov theory is used. A novel feedback gain matrix inspired by the fuel-optimal impulsive solution is designed to achieve near-optimal fuel consumption. LÄS MER
