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

    University essay from KTH/Fastigheter och byggande

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

    Abstract : 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. READ MORE

  2. 2. Tracking of Sinking Underwater Node using Inertial Navigation

    University essay from Mälardalens högskola/Akademin för innovation, design och teknik

    Author : Kristoffer Lindve; [2021]
    Keywords : ;

    Abstract : 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. READ MORE

  3. 3. 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. 4. Calibration and Evaluation of Inertial Navigation with Zero Velocity Update for Industrial Fastening Tools

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

    Author : Johan Rågmark; [2021]
    Keywords : Inertial navigation; Inertial measurement unit; Zero velocity update; Indoor positional navigation; Kalman filter; Tröghetsnavigering; Inertial measurement unit; Zero velocity update; Inomhuspositionering; Kalman filter;

    Abstract : Indoor Positional Navigation (IPN) systems can be used to track the position of tools in factories which is crucial for quality assurance in many manufacturing industries. Inertial navigation is rarely used on its own because of the noisy Inertial Measurement Unit (IMU) sensors which contribute to large drift. READ MORE

  5. 5. 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
