  1. 1. Ranging Error Correction in a Narrowband, Sub-GHz, RF Localization System

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

    Author : Silvia Barrett; [2023]
    Keywords : Localization; Narrowband; Sub-GHz; Radio Frequency; RSSI; Time-of-Flight; Error mitigation; Machine Learning; Linear Regression; LeastSquares Support Vector Machine Regression; Gaussian Process Regression; Loalisering; Narrowband; Sub-GHz; Radiofrekvens; RSSI; Time-of-Flight; Felkorrigering; Machine Learning; Linear Regression; LeastSquares Support Vector Machine Regression; Gaussian Process Regression;

    Abstract : Being able to keep track of ones assets is a very useful thing, from avoiding losing ones keys or phone to being able to find the needed equipment in a busy hospital or on a construction site. The area of localization is actively evolving to find the best ways to accurately track objects and devices in an energy efficient manner, at any range, and in any type of environment. READ MORE

  3. 2. 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

  4. 3. 3D Visualized Indoor Positioning System

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

    Author : Ziqi Xia; Sohrab Mani Alvandian; [2018]
    Keywords : Indoor positioning; Magnetic positioning; Signal transportation; Threedimensional Visualization; Inomhuspositionering; Magnetisk positionering; Signal transportation; Tredimensionell visualisering.;

    Abstract : Three-dimensional visualization refers to the process by which graphical content is created using the Three-dimensional software. While working with Threedimensional visualization, different indoor positioning techniques can be used to detect and track the movement of objects. READ MORE

  5. 4. An experimental investigation of a crossover concept for high accuracy indoor positioning systems

    University essay from Högskolan i Jönköping/JTH. Forskningsmiljö Informationsteknik; Högskolan i Jönköping/JTH, Data- och elektroteknik

    Author : Andreas Lind; [2015]
    Keywords : Bluetooth Low Energy; BLE; Indoor-positioning system; HAIP; Network centric; Mobile centric; Android; Locantis;

    Abstract : To know your whereabouts is important and sometimes exact position is the determinant of success or not. Since the launch of the USA made Global Positioning System (GPS) in the late 1970s, global tracking has been available both for military and civilian use. READ MORE

  6. 5. Indoor Positioning System based on Bluetooth Low Energy for Blind or Visually Impaired Users : Running on a smartphone

    University essay from KTH/Radio Systems Laboratory (RS Lab)

    Author : Tengqingqing Ge; [2015]
    Keywords : RSSI-based indoor positioning; Bluetooth; smartphone; blind and visually impaired; RSSI-baserade inomhuspositionering; Bluetooth; smartphone; blinda och synskadade;

    Abstract : Blind and visually impaired (BVI) users desire an indoor navigation tool that is inexpensive, convenient, and reliable. The purpose of this thesis is to examine the feasibility of using a smartphone as a platform for such a navigation tool. A good navigation tool should have both a good positioning accuracy and a user-friendly interface. READ MORE
