  1. 1. Automatic retrieval of data for industrial machines with handheld devices : Positioning in indoor environments using iBeacons

    University essay from Mittuniversitetet/Institutionen för informationssystem och –teknologi

    Author : Linus Sjöbro; [2021]
    Keywords : RSSI; KNN; fingerprints; indoor positioning; Apple; iOS; application; iBeacon; Beacon;

    Abstract : Positioning of mobile phones or other handheld devices in indoor environments is hard because it’s often not possible to retrieve a GPS-signal. Therefore, other techniques need to be used for this. Despite the difficulties with indoor positioning, the Swedish mining company LKAB want to do exactly this in their processing plants. READ MORE

    Abstract : The new Bluetooth standard (Bluetooth 5.1) contains direction finding specifications. Specifications for received signal strength indicator(RSSI) using measures of signal strength in order to give a sense of how far away an object is has been present in earlier versions. 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. Indoor Positioning and Machine Learning Algorithms

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Raavi Uttarwar; Julián Valentín; [2021]
    Keywords : Indoor Positioning; Machine Learning; Bluetooth Low Energy; Technology and Engineering;

    Abstract : This master thesis focuses around improving the efficiency and accuracy of existing indoor positioning systems with the help of Machine Learning (ML). Our work is based on Bluetooth Low Energy (BLE) v5.1. Position estimation is currently being carried out using the Least-Squares (LS) method in the framework. READ MORE

  5. 5. Positioning and Tracking of Target Drone

    University essay from Linköpings universitet/Kommunikationssystem; Linköpings universitet/Kommunikationssystem

    Author : Anna Hanström; Jet Verheij; [2021]
    Keywords : Tracking; drone; positioning; UAV; filter; RSSI; Interferometry; Particle filter; Kalman filter;

    Abstract : This master thesis studied methods for tracking and localising a moving target from an autonomous seeker drone. Feasible methods for automatic control of the seeker drone and different antenna configurations were explored as well. Two different tracking filters and two different controllers were tested for this purpose. READ MORE
