  1. 11. Robust Autonomous Landing of Fixed-Wing UAVs in Wind

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Tobias Fridén; [2020]
    Nyckelord :Unmanned Aerial Vehicles; Landing; Wind; Optimization; Motion planning;

    Sammanfattning : Fixed-wing UAVs are today used in many different areas, from agriculture to search and rescue operations. Through various research efforts, they are becoming more and more autonomous. However, the procedure of landing a fixed-wing UAV remains a challenging task, which requires manual input from an experienced pilot. LÄS MER

  3. 12. Autonomous Landing of an Unmanned Aerial Vehicle on an Unmanned Ground Vehicle in a GNSS-denied scenario

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Alexander Källström; Albin Andersson Jagesten; [2020]
    Nyckelord :Unmanned Aerial Vehicle; Unmanned Ground Vehicle; Autonomous Landing; Ultra-Wide Band; Proportional Navigation; GNSS-denied Scenario; Gazebo;

    Sammanfattning : An autonomous system consisting of an unmanned aerial vehicle (UAV) in cooperation with an unmanned ground vehicle (UGV) is of interest in applications for military reconnaissance, surveillance and target acquisition (RSTA). The basic idea of such a system is to take advantage of the vehicles strengths and counteract their weaknesses. LÄS MER

  4. 13. Autonomous and Accurate Landing of an Unmanned Aerial Vehicle

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Louise Tylstedt; Simon Ågren; [2020]
    Nyckelord :Technology and Engineering;

    Sammanfattning : During recent years, advancements in mobile technology have enabled the development of quadcopters and unmanned aerial vehicles (UAV) to the point where their size and maneuverability enable indoor flight. In such GPS-denied environments, accurate positioning is a challenge which poses difficulties during flight, navigation and landing. LÄS MER

  5. 14. Robust Relative Positioning & Autonomous Landing of a Flying Wing MAV for Sea Rescue Applications

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Olle Fagerström Hedbrant; Martin Gemborn Nilsson; [2020]
    Nyckelord :Technology and Engineering;

    Sammanfattning : In this thesis, a study is made into relative positioning and control systems for flying wing Micro Aerial Vehicles (MAVs) intended to be used by the Swedish Sea Rescue Society (SSRS) for the purpose of providing assistance during sea rescue missions. The particular scenario of interest is robust relative positioning to be used for autonomous landing of a MAV on a boat at the end of a rescue mission. LÄS MER

  7. 15. Autonomous landing of multicopters on mobile platforms : Design of an autonomous landing solution for multicopters on mobile platforms, based on a ultrasonic local positionning technology

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Mathias Peluchon; [2019]
    Nyckelord :;

    Sammanfattning : This work studies the use of an ultrasonic 3D positioning system in multicopter landing applications. Its aim is to develop a solution for autonomous landing of rotary wings systems on mobile platforms, especially boat decks using the positioning system developed by the French startup Internest.
