  1. 1. Learned Multi-Sensor Indoor Positioning of Mobile Devices

    Master-uppsats, Lunds universitet/Matematik LTH

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

    Sammanfattning : 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. LÄS MER

  3. 2. Evaluation of drift correction strategies for an inertial based dairy cow positioning system. : A study on tracking the position of dairy cows using a foot mounted IMU with drift correction from ZUPT or sparse RFID locations.

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Maria Markovska; Ruben Svensson; [2019]
    Nyckelord :Inertial navigation system; IMU; PDR; dairy cows; drift correction; ZUPT; sparse locations.; Tröghetsnavigeringssystem; IMU; PDR; mjölkkor; driftkorrigering; ZUPT; sparse locations.;

    Sammanfattning : This thesis investigates the feasibility and performance of an inertial based positioning system for dairy cows in a barn environment. The investigated positioning method is pedestrian dead reckoning using inertial navigation with MEMS sensors. LÄS MER

  4. 3. Feasibility Study of Indoor Positioning in a Hospital Environment Using Smartphone Sensors

    Master-uppsats, Linköpings universitet/Reglerteknik
