  1. 11. Enhancing GNSS Precision for Mobile Devices with Sensor Fusion Techniques: A Case Study on eBike Tracking Using State Estimation

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

    Författare :Richard Byström; William Sjödin; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Electric bicycles have over time become a common method of transportation. With a rapidly increasing user base and expensive prices, there is also an increasing demand for safety and insurance. Bike safety can be used to notify the bicycle owner of a potential theft, or to locate the position of the bike when it is lost. LÄS MER

  3. 12. Practical Trials of Fiber Optical Gyroscope Based Inertial Navigation System

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

    Författare :Tim Djärf; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : There exists a need for inertial navigation systems within a multitude of applications, such as drones, unmanned vehicles, and guidance systems. Saab produces gyroscopes for stabilization purposes, but the gyroscopes could also be used as part of an inertial navigation system. LÄS MER

  4. 13. Robotics Approach in Mobile Laser Scanning : Generation of Georeferenced Point-based Forest Models

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

    Författare :Tamas Faitli; [2023]
    Nyckelord :mobile laser scanning; rotating lidar; slam; real-time positioning; georeferencing; state estimation; lidar odometry; point-based forest model; forest harvester; forestry; mobil laserskanning; roterande lidar; slam; realtidspositionering; georeferens; tillståndsuppskattning; lidarodometri; punktbaserad skogsmodell; skogsskördare; skogsbruk;

    Sammanfattning : A mobile laser scanning (MLS) system equipped with a lidar, inertial navigation system and satellite positioning can be used to reconstruct georeferenced point-based models of the surveyed environments. Ideal reconstruction requires accurate trajectories that are challenging to obtain in forests. LÄS MER

  5. 14. A Positioning System for Landing a UAV on a UGV in a GNSS-Denied Scenario

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Tim Wiik; [2022]
    Nyckelord :Sensor fusion; UAV; UGV; NIR-LED; Extended kalman filter; Unmanned Aerial Vehicle; Unmanned Ground Vehicle; Autonomous Landing; GNSS-denied Scenario;

    Sammanfattning : A system of an unmanned aerial vehicle (UAV) collaborating with an unmanned ground vehicle (UGV) for use in for example surveillance, reconnaissance, transport and target acquisition is studied. The project investigates the problem of estimating the relative position, velocity and orientation between the UAV and the UGV required to autonomously land the UAV on the UGV during movement.

  7. 15. Localization of Combat Aircraft at High Altitude using Visual Odometry

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Jenny Nilsson Boij; [2022]
    Nyckelord :Monocular Visual Odometry; Monocular SLAM; High Altitude; Combat Aircraft; X-Plane;

    Sammanfattning : Most of the navigation systems used in today’s aircraft rely on Global Navigation Satellite Systems (GNSS). However, GNSS is not fully reliable. For example, it can be jammed by attacks on the space or ground segments of the system or denied at inaccessible areas. LÄS MER
