  1. 6. GNSS Safety and Handling

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Axel Björklund; [2022]
    Keywords : 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;

    Abstract : 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.

  3. 7. Learned Multi-Sensor Indoor Positioning of Mobile Devices

    University essay from Lunds universitet/Matematik LTH

    Author : Christoffer Kjellson; [2021]
    Keywords : Indoor Positioning; Deep Learning; Fingerprinting; RSSI; Machine Learning; Pedestrian Dead Reckoning; Kaggle; Sensor Fusion; SDAE; LSTM; Technology and Engineering; Mathematics and Statistics;

    Abstract : Attenuation of the microwave signal used in the Global Positioning System (GPS) due to interaction with building structures complicates the task of accurate indoor positioning. For this reason, research on alternative approaches is being performed at universities and companies worldwide. READ MORE

  4. 8. Towards an improvement of BLE Direction Finding accuracyusing Dead Reckoning with inertial sensors

    University essay from Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Author : Tove Rumar; Ludvig Juelsson Larsen; [2021]
    Keywords : Dead Reckoning; Inertial Sensors; Sensor Fusion; Indoor Positioning; Direction Finding;

    Abstract : Whilst GPS positioning has been a well used technology for many years in outdoor environments,a ubiquitous solution for indoor positioning is yet to be found, as GPS positioning is unreliableindoors. This thesis focuses on the combination of Inertial Sensor Dead Reckoning and positionsobtained from the Bluetooth Low Energy (BLE) Direction Finding technique. READ MORE

  5. 9. Smartphone Based Indoor Positioning Using Wi-Fi Round Trip Time and IMU Sensors

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Gustav Aaro; [2020]
    Keywords : Wi-Fi RTT; Indoor positioning; FTM; Android; Smartphone; Sensor fusion; IPS;

    Abstract : While GPS long has been an industry standard for localization of an entity or person anywhere in the world, it loses much of its accuracy and value when used indoors. To enable services such as indoor navigation, other methods must be used. A new standard of the Wi-Fi protocol, IEEE 802. READ MORE

  6. 10. Map-aided localization for autonomous driving using a particle filter

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Simon Eriksson; [2020]
    Keywords : Particle filter; Monte Carlo filter; Gaussian noise; Bayesian estimation; probabilistic localization; autonomous vehicles; Scania; OpenStreetMap; Partikelfilter; Monte Carlo-filter; Gaussiskt brus; Bayesisk uppskattning; sannolikhetsbaserad lokalisering; autonoma fordon; Scania; OpenStreetMap;

    Abstract : Vehicles losing their GPS signal is a considerable issue for autonomous vehicles and can be a danger to people in their vicinity. To circumvent this issue, a particle filter localization technique using pre-generated offline Open Street Map (OSM) maps was investigated in a software simulation of Scania’s heavy-duty trucks.
