  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. 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

  3. 3. Estimating Position and Velocity of Traffic Participants Using Non-Causal Offline Algorithms

    University essay from Linköpings universitet/Reglerteknik

    Author : Casper Johansson; [2019]
    Keywords : Tracking; UKF; RTS; Non-causal; Vehicle tracking; Estimation;

    Abstract : In this thesis several non-causal offline algorithms are developed and evaluated for a vision system used for pedestrian and vehicle traffic. The reason was to investigate if the performance increase of non-causal offline algorithms alone is enough to evaluate the performance of vision system. READ MORE

  4. 4. Advanced Filter Design for Autonomous Vehicles

    University essay from KTH/Fordonsdynamik; KTH/Fordonsdynamik

    Author : Alexander Frölin; Carl Säflund; [2019]
    Keywords : ;

    Abstract : The introduction of autonomous vehicles comes with many benefits related to safety and quality-of-life, the implementation of which is a challenging task for engineers to solve; one part of this aforementioned task is the requirement for precise positioning.Firstly, this thesis work investigated the contemporary fields of science rel-evant for the task of position estimation.

  5. 5. State- and Parameter Estimation for Spacecraft with Flexible Appendages using Unscented Kalman Filters

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Andrea Mosquera Alonso; [2019]
    Keywords : Estimation; flexibility; flexible spacecraft; spacecraft; kalman filter; unscented Kalman filter; spacecraft dynamics; flexible dynamics;

    Abstract : The problem of system identification for dynamic effects on spacecraft has become increasingly relevant with the surge of agile spacecraft, which must perform large amplitude maneuvers at high rates. Precise knowledge of the state of the spacecraft, as well as of the parameters characterizing its motion, is vital for the design of control algorithms enabling stabilization and pointing accuracy.
