  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. Virtual alignment of real-world objects

    University essay from Stockholms universitet/Institutionen för data- och systemvetenskap

    Author : Tommy Ekberg; William Ekelund; [2023]
    Keywords : Ultra-wideband; Indoor positioning system; Document survey; NLoS; Multisensor; Trilateration; Localization;

    Abstract : High accuracy localization of objects is a crucial function for many modern applications, such as virtual and augmented reality, robotics, and self-driving cars, among others. This requires determining precise location of objects indoors, which is a challenging task. READ MORE

  4. 3. An evaluation of LoRa transmission parameter selection for indoor positioning

    University essay from Jönköping University/JTH, Avdelningen för datateknik och informatik

    Author : Adina Valjakka; Anton Ahlinder; [2022]
    Keywords : Accuracy; Indoor positioning; LoRa; NLOS; Precision; RSSI; Transmission parameters; Trilateration;

    Abstract : The purpose of this thesis is to investigate how the LoRa modulation configuration affects precision and accuracy when using LoRa for indoor positioning in non-line-of-sight conditions. The aim is to research if an optimum combination of spreading factor, bandwidth, and code rate factor can be found to result in the best possible positioning accuracy and precision, under certain predefined conditions.

  5. 4. Autonomous medical robot

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Ana Almer Casino; Miguel Ángel Sempere Vicente; [2020]
    Keywords : ;

    Abstract : Lack of healthcare assistance is one of the issues that European countries such as Sweden face due to the increase of the ageing phenomenon which leads to a higher demand for personnel in hospitals, basic attendance, and housing. Therefore, a tool is clearly required to fulfil these social needs. READ MORE

  6. 5. 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
