  1. 11. A Study on Long Short-Term Memory Networks Applied to Local Positioning

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Todd Barker; Martin Åkerblad; [2018]
    Nyckelord :;

    Sammanfattning : Numerical approaches to lateration and sensor fusion are limited by inherent measurementerrors and the positioning performance may benefit from alternative approaches.This thesis studies the applicability of deep learning to an Ultra Wide Band (UWB)based local positioning problem in a combination of readings from an Inertial MeasurementUnit (IMU).

  3. 12. 5G Positioning using Machine Learning

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Magnus Malmström; [2018]
    Nyckelord :5G; Positioning; Non Line of Sight NLOS ; Urban Canyons; Machine Learning; Neural Networks; Random Forest; Detection; Neyman-Person; Generalized Likelihood Ratio Test; Kalam Filter;

    Sammanfattning : Positioning is recognized as an important feature of fifth generation (\abbrFiveG) cellular networks due to the massive number of commercial use cases that would benefit from access to position information. Radio based positioning has always been a challenging task in urban canyons where buildings block and reflect the radio signal, causing multipath propagation and non-line-of-sight (NLOS) signal conditions.

  4. 13. A Study on Long Short-Term Memory Networks Applied to Local Positioning

    Master-uppsats, KTH/Mekatronik

    Författare :Todd Barker; Martin Åkerblad; [2018]
    Nyckelord :;

    Sammanfattning : Numerical approaches to lateration and sensor fusion are limited by inherent measure-ment errors and the positioning performance may benefit from alternative approaches. This thesis studies the applicability of deep learning to an Ultra Wide Band (UWB) based local positioning problem in a combination of readings from an Inertial Mea-surement Unit (IMU). LÄS MER

  5. 14. Object Identifier System for Autonomous UAV : A subsystem providing methods for detecting and descending to an object. The object is located in a specified area with a coverage algorithm.

    M1-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Patrick Karlsson; Emil Johansson; [2018]
    Nyckelord :;

    Sammanfattning : Using UAVs in everyday life has been increasing in recent years. UAV is an agile vehicle and often comes integrated with a camera and sensors which makes it suitable for object detection and tracking. In this thesis, we present a subsystem with a limited hardware setup only consisting of an on-board computer and a camera that is mounted on a UAV. LÄS MER

  7. 15. Feasibility Study of Indoor Positioning in a Hospital Environment Using Smartphone Sensors

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Joakim Skytte; [2017]
    Nyckelord : Indoor positioning ; smartphone; IMU; Wi-Fi; Dead Reckoning ; Inomhuspositionering; tröghetsnavigering; wifi;

    Sammanfattning : This thesis is a feasibility study of contemporary indoor positioning approaches in an hospital environment using sensor available on Android phones together with Wi-Fi fingerprintingand map information. The purpose is to determine the resolution of pedestrian indoor positioning and whether it is sufficient for room level accuracy. LÄS MER
