  1. 6. Estimating a Boat’s Vertical Velocity with Unpositioned 6DOF IMU:s : How sensor fusion and knowledge of the system dynamics can be used to estimate the IMU positions and produce fused estimates

    University essay from Linköpings universitet/Fordonssystem

    Author : Jesper Sjöblom; [2023]
    Keywords : IMU data fusion; Extended Kalman Filter; IMU positioning;

    Abstract : Longline fishing is a method of fishing that utilizes baited hooks to catch fish in an environmentally friendly way. In order to reduce the number of catch lost while longline fishing, it is of great interest to be able to keep an even tension on the fishing line. READ MORE

  3. 7. Formation Control of UAVs for Positioning and Tracking of a Moving Target

    Author : Daniel Sandvall; Eric Sevonius; [2023]
    Keywords : UWB; Relative positioning; Sensor fusion; UAV; Formation flight; Fixed wing; Relative localization; EKF; FGO;

    Abstract : In recent years, the interest in flying multiple Unmanned Aerial Vehicles (UAVs) in formation has increased. One challenging aspect of achieving this is the relative positioning within the swarm. READ MORE

  6. 10. A Positioning System for Landing a UAV on a UGV in a GNSS-Denied Scenario

    University essay from Linköpings universitet/Institutionen för systemteknik

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

    Abstract : 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.
