  1. 11. Positioning and Tracking of Target Drone

    University essay from 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

  3. 12. BLE Beacon Based Indoor Positioning System in an Office Building using Machine Learning

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Rohan Reddy Tirumalareddy; [2020]
    Keywords : Indoor Positioning System; Fingerprinting; Machine Learning; Bluetooth Low Energy;

    Abstract : Context: Indoor positioning systems have become more widespread over the past decade, mainly due to devices such as Bluetooth Low Energy beacons which are low at cost and work effectively. The context of this thesis is to localize and help people navigate to the office equipment, meeting rooms, etc. READ MORE

  4. 13. Multi-Factor Mobile based Access Control Solution

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

    Author : August Larsson; Alvin Ohlsson; [2020]
    Keywords : Indoor positioning Wi-Fi Fingerprinting Magnetic Fingerprinting; Technology and Engineering;

    Abstract : In this thesis, alternatives for replacing an RFID card + PIN based access controlsolution for office buildings with a mobile applications are evaluated. The proposedsolutions are based on a probabilistic fingerprinting approach where distributionsof RSSI are approximated and stored in a fingerprint database during an initialoffline phase. READ MORE

  5. 14. Evaluation of Bluetooth 5.1 as an Indoor Positioning System

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Philip Andersson; Linus Persson; [2020]
    Keywords : Indoor Positioning System; AoA; RSSI; IMU; Sensor Fusion; Multipath Propagation; Inomhus positioneringssystem; AoA; RSSI; IMU; Sensor Fusion; Flervägsutbredning;

    Abstract : There is a high demand for Indoor Positioning Systems (IPS) due to the wide application possibilities. The main issue for localization by wireless signals in an indoor environment is the multipath propagation problem. Multipath propagation occurs when signals reflects and refract from an object, changing the signals characteristics. READ MORE

  6. 15. Relay Attack Resistant Passive Keyless Entry : Securing PKE Systems with Immobility Detection

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : ABEL VALKO; [2020]
    Keywords : Passive Keyless Entry; Relay Attack; Mafia Fraud; Access Control; Mechatronics; Nyckellös System; åtkomstkontroll; Relay Attack; IT-säkerhet; Mekatronik;

    Abstract : A significant security risk of modern vehicles is their vulnerability to relay attacks, due to challenge-response methods, such as those employed in Passive Keyless Entry (PKE) used by most commercial cars, being inherently exposed. This class of attacks are where communication between a vehicle and its key is relayed by an attacker over long range - thereby bypassing any encryption and unlocking the vehicle without requiring direct access to the key.
