  1. 1. 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

  2. 2. Unmanned Aerial Vehicle Positioning Using a Phased Array Radio and GNSS Independent Sensors

    University essay from Linköpings universitet/Reglerteknik

    Author : Carl Rapp; [2019]
    Keywords : Sensorfusion; Kalman filter; Phased Array Radio; UAV; Positioning;

    Abstract : This thesis studies the possibility to replace the global navigation satellite system (GNSS) with a phased array radio system (PARS) for positioning and navigation of an unmanned aerial vehicle (UAV). With the increase of UAVs in both civilian and military applications, the need for a robust and accurate navigation solution has increased. READ MORE

  3. 3. 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.

  4. 4. Aiding Navigation for Groups of Aircraft with Bearing and Distance Measurements

    University essay from Linköpings universitet/Reglerteknik

    Author : Mattias Olsson; [2018]
    Keywords : Navigational enhancing; consensus filtering;

    Abstract : This thesis extends previous work on navigational aidingof groups of aircraft, primarily intended for the fighter SAAB JAS 39 Gripen,as long as an aircraft gets GPS signals, it is easy to estimate position, but theGPS is relatively easy to jam, rendering alternative methods of positioning necessary.To use internal sensors measuring accelerations and angular velocities is agood replacement on short terms, but gives a drift in positioning over longer timeperiods.

  5. 5. Analysis of autonomous flight algorithms for an unmanned aerial vehicle

    University essay from Umeå universitet/Institutionen för fysik

    Author : Mattias Sjöberg; [2018]
    Keywords : UAV; SLAM; Split-And-Merge; APFA; V-REP; Inverse dynamics; FBLC; EKF;

    Abstract : Unmanned Aerial Vehicles (UAV) have been heavily studied in the past decade, where autonomous flights have been a popular subject. More complex applications have led to higher requirements on the autonomous flight algorithms and the absence of performance data complicates the selection of what algorithm to use for various applications.
