  1. 1. Trajectory Optimisation of a Spacecraft Swarm Maximising Gravitational Signal

    Master-uppsats, KTH/Optimeringslära och systemteori

    Författare :Rasmus Maråk; [2023]
    Nyckelord :Spacecraft Swarms; Trajectory Optimisation; Impulsive Manoeuvres; Evolutionary Algorithms; Polyhedral Gravity Model; Small Body Exploration; Discrete Spherical Grids; Svärmande rymdfarkoster; Banoptimering; Impulsiva manövrar; Evolutionära Algoritmer; Polyhedral gravitationsmodell; Utforksning av små kroppar i solsystemet; Diskreta sfäriska rutnät;

    Sammanfattning : Proper modelling of the gravitational fields of irregularly shaped asteroids and comets is an essential yet challenging part of any spacecraft visit and flyby to these bodies. Accurate density representations provide crucial information for proximity missions, which rely heavily on it to design safe and efficient trajectories. LÄS MER

  4. 3. Determination of Proton Beam Waist Positions Using Beam Position Monitors

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB; Lunds universitet/Synkrotronljusfysik

    Författare :Gustav Gird Fahlström; [2022]
    Nyckelord :ESS; European Spallation Source; Proton beam; waist; BPM; Method; transverse; beam dynamics; beam physics; Lattice Error; Matrix formalism; Python; trajectory simulation; physics; Physics and Astronomy;

    Sammanfattning : In this work, we examine a novel method for the determination of proton beam waist locations using beam position monitors. Based on the lattice of the final transport line section of the European Spallation Source linac, a simplified version of the beam line composed of quadrupole magnets and correctors is constructed in Python using a matrix formalism.

  5. 4. AUV SLAM constraint formation using side scan sonar

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

    Författare :Marco Schouten; [2022]
    Nyckelord :AUV; Side Scan Sonar; Pose Estimation; SLAM; Optimisation; AUV; Side Scan Sonar; Pose Estimation; SLAM; Optimisation;

    Sammanfattning : Autonomous underwater vehicle (AUV) navigation has been a challenging problem for a long time. Navigation is challenging due to the drift present in underwater environments and the lack of precise localisation systems such as GPS. Therefore, the uncertainty of the vehicle’s pose grows with the mission’s duration. LÄS MER

  7. 5. Aircraft Contrail Prediction for Commercial Flights

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Chirag Kundgol; [2022]
    Nyckelord :Contrail prediction; Aircraft trajectory optimisation; Kondensstrimmor; förutsägelse; optimering;

    Sammanfattning : The prediction of contrails have been studied since the 1930s primarily for militaryapplications. In present times, contrail avoidance strategies are gaining popularity insustainable aviation. In this project, the theory behind their formation, persistenceand the mitigation strategies are explored, studied and implemented. LÄS MER
