  1. 1. Smartphone Based Indoor Positioning Using Wi-Fi Round Trip Time and IMU Sensors

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Gustav Aaro; [2020]
    Keywords : Wi-Fi RTT; Indoor positioning; FTM; Android; Smartphone; Sensor fusion; IPS;

    Abstract : While GPS long has been an industry standard for localization of an entity or person anywhere in the world, it loses much of its accuracy and value when used indoors. To enable services such as indoor navigation, other methods must be used. A new standard of the Wi-Fi protocol, IEEE 802. READ MORE

  2. 2. Robot Localization with Radio Frequency Identification and Time Difference of Arrival

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

    Author : Håkan Göransson; [2020]
    Keywords : ;

    Abstract : In today’s robot technology it is important to have a system that enables fora robot to find its own position. This can be achieved with different kinds ofsensors, such as LIDAR, GPS and cameras, and sensor fusion. READ MORE

  3. 3. The Effects of Sensor Fusion on Localisation in a Sparse, Outdoor Environment

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Kayla Kearns; [2020]
    Keywords : ;

    Abstract : This thesis compares the results of a localisation algorithm for a mobile robot in both a sparse and a densely featured environment whilst varying key parameters. The software and hardware required to enable the mobile robot to localise itself in the sparsely featured, GPS-denied, outdoor environment is described. READ MORE

  4. 4. GPS-oscillation-robust Localization and Visionaided Odometry Estimation

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : HONGYI CHEN; [2019]
    Keywords : Adaptive Extended Kalman Filter; Localization; Stereo visual odometry; GPS outage; Adaptivt förlängt Kalmanfilter; lokalisering; stereovisuell odometri; GPS avbrott;

    Abstract : GPS/IMU integrated systems are commonly used for vehicle navigation. The algorithm for this coupled system is normally based on Kalman filter. However, oscillated GPS measurements in the urban environment can lead to localization divergence easily. READ MORE

  5. 5. Identification of absolute orientation using inertial measurement unit

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi; Högskolan i Halmstad/Akademin för informationsteknologi

    Author : André Kopfinger; Daniel Ahlsén; [2019]
    Keywords : Indoor navigation; absolute orientation; inertial measurement unit; IMU; indoor positioning;

    Abstract : Because of the limitation of GPS indoors there is a demand for alternative methods to accurately determine both position and orientation. Previous attempts at positional tracking has required an infrastructure of hardware and sensors to provide the path of an object or person. This is not a mobile solution to a mobile problem. READ MORE
