  1. 21. Evaluation of Drone Neutralization Methods using Radio Jamming and Spoofing Techniques

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

    Författare :David Jan Rozenbeek; [2020]
    Nyckelord :C-UAS; Drone; UAV; Counter-drone; Jamming; GPS Spoofing;

    Sammanfattning : The usage of drones is steadily increasing as drones are becoming more available and useful to the general public, but drone usage also leads to problems as for example airports have had to shutdown due to drone sightings. It has become clear that a counter-drone system must be in place to neutralize intruding drones. LÄS MER

  3. 22. Användning av UAV för datainsamling för 3D-modeller : Undersökning av flyg- och fotograferingsparametrar för UAV

    M1-uppsats, Karlstads universitet

    Författare :Pontus Kempe; [2019]
    Nyckelord :drone; UAV; 3D modelling; drönare; UAV; 3D-modellering;

    Sammanfattning : In this thesis, 12 aerial photographs flights were taken over a small building in the municipality of Trosa, with a drone, or the correct name in this case is UAV (Unmanned Aerial Vehicle). Where the purpose was to create 3D models from the aerial images. LÄS MER

  4. 23. Guidance strategies for the boosted landing of reusable launch vehicles

    Master-uppsats, KTH/Rymdteknik

    Författare :Agathe Carpentier; [2019]
    Nyckelord :guidance; Callisto; convex optimization; adaptative pseudo-spectral interpolation; GNC; thesis;

    Sammanfattning : This document presents the results of the master thesis conducted from April 2019 to October 2019 under the direction of CNES engineer Eric Bourgeois, as part of the KTH Master of Science in Aerospace Engineering curriculum. Within the framework of development studies for the Callisto demonstrator, this master thesis aims at studying and developing possible guidance strategies for the boosted landing. LÄS MER

  5. 24. Long term chaotic attitude behaviour on highly eccentric orbits : INTEGRAL Case Study

    Master-uppsats, KTH/Farkost och flyg

    Författare :Davide Menzio; [2016]
    Nyckelord :long-term propagation; attitude; stability; Poincaré map; momentum sphere.;

    Sammanfattning : The main issues discussed in this paper are related to the refinement of the on-ground casualty risk computation for the specific case of INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL). The current approach, unable to predict the spacecraft attitude motion, assumes random tumbling motion as initial condition to simulate the fragmentation process. LÄS MER

  7. 25. Attitude Determination and Control of the CubeSat MIST

    Master-uppsats, KTH/Farkost och flyg

    Författare :Jiewei Zhou; [2016]
    Nyckelord :;

    Sammanfattning : The ADCS concept in MIST reects the limitations of the CubeSat in terms of space, power and onboard computer computational capability. The control is constrained to the use of only magnetic torquers and the determination to magnetometers and Sun sensors in spite of the the under-actuation and underdetermination during eclipses.
