16. Robust Graph SLAM in Challenging GNSS Environments Using Lidar Odometry
University essay from Linköpings universitet/ReglerteknikAbstract : Localization is a fundamental part of achieving fully autonomous vehicles. A localization system needs to constantly provide accurate information about the position of the vehicle and failure could lead to catastrophic consequences. READ MORE

17. Robotics Approach in Mobile Laser Scanning : Generation of Georeferenced Point-based Forest Models
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : A mobile laser scanning (MLS) system equipped with a lidar, inertial navigation system and satellite positioning can be used to reconstruct georeferenced point-based models of the surveyed environments. Ideal reconstruction requires accurate trajectories that are challenging to obtain in forests. READ MORE

18. Distributed Relay/Replay Attacks on GNSS Signals
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : In modern society, Global Navigation Satellite Systems (GNSSs) are ubiquitously relied upon by many systems, among others in critical infrastructure, for navigation and time synchronization. To overcome the prevailing vulnerable state of civilian GNSSs, many detection schemes for different attack types (i.e. READ MORE

19. GPS-Free UAV Geo-Localization Using a Reference 3D Database
University essay from Linköpings universitet/Institutionen för systemteknikAbstract : The goal of this thesis has been global geolocalization using only visual input and a 3D database for reference. In recent years Convolutional Neural Networks (CNNs) have seen huge success in the task of classifying images. The flattened tensors at the final layers of a CNN can be viewed as vectors describing different input image features. READ MORE

20. A Positioning System for Landing a UAV on a UGV in a GNSS-Denied Scenario
University essay from Linköpings universitet/Institutionen för systemteknikAbstract : A system of an unmanned aerial vehicle (UAV) collaborating with an unmanned ground vehicle (UGV) for use in for example surveillance, reconnaissance, transport and target acquisition is studied. The project investigates the problem of estimating the relative position, velocity and orientation between the UAV and the UGV required to autonomously land the UAV on the UGV during movement.
