  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
