  1. 1. 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.

  2. 2. 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

  3. 3. Model-based Generation of a Sensor Reading Web Test Tool

    Kandidat-uppsats, Lunds universitet/Institutionen för datavetenskap

    Författare :Jonas Andersson; Christoffer Lindell Bolin; [2022]
    Nyckelord :WISE; GUI; REST; Testing; Integration; Technology and Engineering;

    Sammanfattning : This Bachelor’s thesis is in collaboration with Saab Kockums AB. Saab Kockums develops and constructs marine technology, ships and submarines for civil and military use. LÄS MER

  4. 4. USING N-MODULAR REDUNDANCYWITH KALMAN FILTERS FORUNDERWATER VEHICLE POSITIONESTIMATION

    Master-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

    Författare :Axel Enquist; [2022]
    Nyckelord :MATLAB; Simulink; Kalman filter; n-Modular Redundancy; Underwater;

    Sammanfattning : Underwater navigation faces many problems with accurately estimating the absolute positionof an underwater vehicle. Neither Global Positioning system (GPS) nor Long Baseline (LBL) orShort Baseline (SBL) are possible to use for a military vehicle acting under stealth, since thesetechniques require the vehicle to be in the vicinity of a nearby ship or to surface and raise its antenna.

  5. 5. GNSS Safety and Handling

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Axel Björklund; [2022]
    Nyckelord :Navigation; GNSS; GPS; Galileo; OSNMA; TESLA protocol; SHA-256; jamming; spoofing; SDR; GPS-SDR-SIM; Smart Tachograph; dead reckoning; U-blox; Volvo Group; Volvo FH;

    Sammanfattning : Satellite navigation (such as GPS) has become widely successful and is used by billions of users daily. Accuratepositioning and timing has a wide range of applications and is increasingly being integrated in safety criticalsystems such as autonomous operations, traffic management, navigation for airplanes and other vehicles.
