  1. 21. Analysis of Positional Precision when Using Ground Control Points with Supported INS in GNSS-Free Environments

    Master-uppsats, KTH/Fastigheter och byggande

    Författare :Linus Bäckström; Patrik Grenert; [2021]
    Nyckelord :Track maintenance; GNSS; INS; GCP; GNSS-free environments; Railway positioning; Rälsunderhåll; GNSS; INS; Kända punkter; Avsaknad av GNSS; Positionering på räls;

    Sammanfattning : Railway traffic is one of the most used transportation methods in today's society both for freight transports and transportation of people. A necessity for this to function is that the tracks upon which the trains travel are functional. LÄS MER

  3. 22. Benchmarking VisualInertial Odometry Filterbased Methods for Vehicles

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Muhammad Zahid; [2021]
    Nyckelord :visual inertial odometry; VIO; sensor fusion; state estimation; recursive filter; navigation; autonomous vehicles; visuell tröghetsodometri; VIO; sensorfusion; tillståndsuppskattning; rekursivt filter; navigering; autonoma fordon;

    Sammanfattning : Autonomous navigation has the opportunity to make roads safer and help perform search and rescue missions by reducing human error. Odometry methods are essential to allow for autonomous navigation because they estimate how the robot will move based on the available sensors. LÄS MER

  4. 23. Gps Spoofing Simulator

    Master-uppsats, KTH/Flygdynamik

    Författare :Julien Nguyen; [2021]
    Nyckelord :;

    Sammanfattning : This paper, written at Safran Electronics & Defense as part of the author’s Master Thesis, is dedicated to the implementation of a GNSS alternate trajectory simulator for an aircraft GPS-aided Inertial Navigation System. First, the basic tenets of GPS-aided inertial navigation systems will be briefly reminded. LÄS MER

  5. 24. Tracking of Sinking Underwater Node using Inertial Navigation

    Master-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

    Författare :Kristoffer Lindve; [2021]
    Nyckelord :;

    Sammanfattning : Tracking objects underwater is prone to error since no equivalent system to GPS exists for underwater applications. Accurate positioning is vital for conducting surveillance. However, it is hard for a system to keep an accurate prediction while moving without a GPS source. LÄS MER

  7. 25. 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
