    Sammanfattning : This paper investigates the potential of augmented reality (AR) as a navigational aid for individuals with Alzheimer’s disease (AD), offering innovative solutions to the evolving challenges of AD care. As the disease progresses, patients often require more assistance and may transition to care centers, resulting in reduced independence. LÄS MER

  3. 2. Enhancing GPR Measurements using Real Time Kinematics and LiDAR Mapping

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

    Författare :Christoffer Elebro; [2022]
    Nyckelord :GPS; GNSS; RTK; Lidar; 3D-mapping;

    Sammanfattning : A Ground Penetrating Radar (GPR) is a non-invasive measurement tool to locate objects in the subsurface. The GPR transmits electromagnetic waves into the ground and records the waves reflected from surface interfaces of different materials. LÄS MER

  4. 3. 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.

  5. 4. The Effect of Distortions Induced by Adaptive Antenna Arrays in GNSS Applications

    Master-uppsats, Linköpings universitet/Kommunikationssystem; Linköpings universitet/Tekniska fakulteten

    Författare :Emma Beskow; [2022]
    Nyckelord :GNSS; GPS; Jamming; Beamforming; Adaptive antenna arrays; Frequency response distortions;

    Sammanfattning : Global Navigation Satellite Systems (GNSS) are vital tools for accurate navigation and timing for both civil and military use. Due to the low power of the GNSS signals, these systems are sensitive to interference attacks. For wideband GNSS jamming, adaptive antenna arrays are commonly used to suppress interference. LÄS MER

  7. 5. Integration of a Software-Defined Baseband for Nano Satellites

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

    Författare :Petter Lindberg; [2022]
    Nyckelord :;

    Sammanfattning : The number of Nano satellites launched into space is increasing rapidly each year. All satellites need a ground station with a baseband to communicate with. Current commercial basebands for TT&C (telemetry, tracking and command) are using proven designs and are too expensive to be used for Nano satellites. LÄS MER
