1. 1. Formation Control of UAVs for Positioning and Tracking of a Moving Target

   Master-uppsats, Linköpings universitet/Fordonssystem

   Författare :Robert Carsk; Alexander Jeremic; [2023]
   Nyckelord :Autonomous; UAVs; Drones; Sensor Fusion; MPC; Filter; KF; EKF; Signal; Tracking; Formation; Controller; Control; MWSN; Optimal Control Problem; Optimization; Seeker Drone; Target Drone; Quadcopter Model; Simulation;

   Sammanfattning : The potential of Unmanned Aerial Vehicles (UAVs) for surveillance and military applications is significant — with continued technical advances in the field. The number of incidents where UAVs have intruded into unauthorized areas has increased in recent years and armed drones are commonly used in modern warfare. LÄS MER

3. 2. Autonomous UAV Path Planning using RSS signals in Search and Rescue Operations

   Master-uppsats, Linköpings universitet/Reglerteknik

   Författare :Axel Anhammer; Hugo Lundeberg; [2022]
   Nyckelord :UAV; DQN; Deep Q Network; particle filter; point mass filter; MDP; POMDP; Markov decision process; partially observable Markov decision process;

   Sammanfattning : Unmanned aerial vehicles (UAVs) have emerged as a promising technology in search and rescue operations (SAR). UAVs have the ability to provide more timely localization, thus decreasing the crucial duration of SAR operations. LÄS MER

4. 3. Multilateration in Direct ShortRange Communications Networks : Utilising Basic Safety Messages and Received Signal Strength Ranging

   Kandidat-uppsats, Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

   Författare :Andrew Galbraith; [2020]
   Nyckelord :DSRC; trilateration; multilateration; RSS; V2X;

   Sammanfattning : Traditional satellite positioning systems have limited resolution and have proved inaccuratein areas such as urban canyons where signals are subject to bounce phenomena or indeed may be entirely unavailable. An alternative method of positioning is that of tri/multilateration, which uses known positions and distances from beacon points to locate a receiver. LÄS MER

5. 4. Localization of eNodeBs with a Large Set of Measurements from Train Routers

   Master-uppsats, Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

   Författare :Simon Sundberg; [2019]
   Nyckelord :Localization; Positioning; LTE; eNodeB; base stations; Received Signal Strength; RSS;

   Sammanfattning : This master thesis investigates the possibility of locating LTE base stations, known as eNodeBs, using signal measurements collected by routers on trains. Four existing algorithms for transmitter localization are adopted: the centroid, strongest signal, Monte Carlo path loss simulation and power difference of arrival (PDoA) methods. LÄS MER

7. 5. Non-Coherent Radio-Based Positioning

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Farshid Rezaei; Mohamad Abou Nasa; [2019]
   Nyckelord :target localization and tracking; wireless sensor network WSN ; hybrid measurements; received signal strength RSS ; angle of arrival AoA ; Technology and Engineering;

   Sammanfattning : In this thesis, a new Angle-of-Arrival (AoA) technique is used to determine the direction of a target in an outdoor environment using Radio Frequency (RF) signals. This technique estimates the AoA based on the difference between the Received Signal Strength Indicators (RSSI) from two/four directive antennas. LÄS MER
