  6. 20. Simultaneous Localization and Mapping for an Unmanned Aerial Vehicle Using Radar and Radio Transmitters

    University essay from Linköpings universitet/Reglerteknik; Linköpings universitet/Tekniska högskolan

    Author : Alfred Dahlin; [2014]
    Keywords : SLAM; simultaneous localisation and mapping; UAV; unmanned aerial vehicle; bearing-only; EKF SLAM; radio transmitters;

    Abstract : The Global Positioning System (GPS) is a cornerstone in Unmanned Aerial Vehicle (UAV) navigation and is by far the most common way to obtain the position of a UAV. However, since there are many scenarios in which GPS measurements might not be available, the possibility of estimating the UAV position without using the GPS would greatly improve the overall robustness of the navigation.
