  1. 1. Real-Time Navigation for Swarms of Synthetic Aperture Radar (SAR) Satellites

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Antoni Eritja Olivella; [2024]
    Nyckelord :SAR; Real-time orbit determination; Real-time baseline determination; swarms; satellite; formation flying;

    Sammanfattning : The pursuit of precision and flexibility in satellite missions has led to an increased number of formation flying missions being developed. These systems consist of multiple satellites flying at close distances (from a few kilometres to a few meters) to achieve common objectives. LÄS MER

  3. 2. Collaborative Mapping with Drone Swarms Utilizing Relative Distance Measurements

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Johan Forsman; Carl Tidén; [2023]
    Nyckelord :;

    Sammanfattning : The field of use for unmanned aerial vehicles, UAVs, has completely exploded in the last decade. Today they are used for surveillance missions and inspecting places that are difficult for people to access. To increase the efficiency and robustness in the execution of these types of missions, swarms of cooperating drones can be used. LÄS MER

  4. 3. Robust light source detection for AUV docking

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

    Författare :Joar Edlund; [2023]
    Nyckelord :Autonomous Underwater Vehicle; Docking; Detection; Poseestimation; Visual Navigation; Autonoma Undervattensfordon; Dockning; Detektering; Positionsestimering; Visuell Navigation;

    Sammanfattning : For Autonomous Underwater Vehicles (AUVs) to be able to conduct longterm surveys, the ability to return to a docking station for maintenance and recharging is crucial. A dynamic docking system where a slowly moving submarine acts as the docking station provides increased hydrodynamic control and reduces the impact of environmental disturbances. LÄS MER

  5. 4. Machine Learning-based MIMO Indoor Positioning

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Qiyi Chen; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The most widely used positioning system is Global Navigation Satellite System (GNSS), which uses traditional positioning techniques and cannot achieve satisfactory positioning performance in indoor scenarios due to Non-Line-of-Sight (NLoS) transmission. Fingerprinting is a non-traditional positioning technique that is robust to NLoS transmission in indoor scenarios. LÄS MER

  7. 5. Data Reduction and Analysis with the MPRu instrument for Neutron Emission Spectroscopy at JET

    Master-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Steven Hendrik Bijl; [2023]
    Nyckelord :Fusion; JET; MPRu;

    Sammanfattning : This research project centres on advancing data analysis techniques using the Magnetic Proton Recoil Upgrade Neutron Spectrometer (MPRu) for neutron emission spectroscopy during the deuterium tritium experimental campaign (DTE2) at the Joint European Torus (JET). The study aimed to address three pivotal questions, each with implications for optimizing data accuracy, quality, and utility. LÄS MER
