  1. 21. Demonstrator Development for Phone as a Key Based on Bluetooth Low Energy

    Master-uppsats, Linköpings universitet/Fysik och elektroteknik; Linköpings universitet/Tekniska högskolan

    Författare :Eric Karlsson; Alexander Lagerbielke; [2017]
    Nyckelord :PaaK; Neural Networks; RSSI; BLE;

    Sammanfattning : In this work a demonstrator for phone as a key has been developed. This demonstrator estimates the position of a mobile device in and around a test vehicle. Trilateration, ROCRSSI and fingerprinting with neural networks have been investigated for the localization of the mobile device. LÄS MER

  3. 22. Development of a Novel Relative Localization Sensor

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Anton Kohlbacher; [2017]
    Nyckelord :Relative Localization; Ultra-wideband; Particle Swarm Optimization; Swarm Robotics; Trilateration; Angulation;

    Sammanfattning : By enabling coordinated task execution and movement, robotic swarms can achieve efficient exploration or disaster site management. When utilizing Ultra-wideband (UWB) radio technology for ranging, the proposed relative localization sensor can be made lightweight and relatively indifferent to the ambient environment. LÄS MER

  4. 23. Användning av BLE-beacons för inomhuspositionering

    Kandidat-uppsats, Lunds universitet/Högskoleingenjörsutbildning i datateknik

    Författare :Albin Cederblad; Mattias Berlin; [2017]
    Nyckelord :bluetooth low energy; ble; beacon; eddystone; smartphone; indoor location; indoor positioning system; android; java; Technology and Engineering;

    Sammanfattning : I detta examensarbete undersöks hur Bluetooth Low Energy (BLE) beacons kan användas för att implementera ett inomhuspositioneringssystem. För att göra detta utvecklades en prototyp som består av en Android-applikation och en DynamoDB-databas. LÄS MER

  5. 24. Indoor localization of hand-held Shopping Scanners

    M1-uppsats, KTH/Data- och elektroteknik

    Författare :Lucas Persson; Sebastian Markström; [2017]
    Nyckelord :Indoor navigation; Inertial measurement unit; Dead reckoning; Pedestrian dead reckoning; Bluetooth; Ultra-Wideband; Trilateration; Shopping scanner; Particle filter; Inomhus navigering; Inertial measurement unit; Dead reckoning; Pedestrian dead reckoning; Bluetooth; Ultra-Wideband; Trilateration; Shopping scanner; Partikel filter;

    Sammanfattning : This thesis investigates applicable indoor navigation systems for the next generation of hand-held shopping scanners, on behalf of the company Virtual Stores. The thesis research and review applicable indoor localization methods and ways to combine and evaluate received localization data in order to provide accurate navigation without introducing any other worn equipment for a potential user.

  7. 25. Outdoor localization in long range WSN using trilateration

    Master-uppsats, Linköpings universitet/Fysik och elektroteknik; Linköpings universitet/Tekniska fakulteten

    Författare :Tom Karlsson; Mike Persson; [2017]
    Nyckelord :;

    Sammanfattning : This thesis report investigates how good position estimations that can be done outdoors with received signal strength indication (RSSI) trilateration for sub 1-GHz radio nodes. A custom network and an empirical distance model have been created as well as a technique for weighting multiple distance estimations, using wrapped normal probability density functions. LÄS MER
