  1. 21. Utilising Raw GNSS Data from Android Units to Improve Positioning

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Karin Seifert; [2022]
    Keywords : ;

    Abstract : In this study it was examined if positioning can be improved by utilising raw Global Navigation Satellite System (GNSS) data from Android devices instead of using Android's existing Location API. If this is the case, the coworkers at BM System may modify their apps, one is called Loco, to develop one that calculates positions directly by utilising raw GNSS data instead of using Android's Location API which is done presently.

  3. 22. Anomalous Behavior Detection in Aircraft based Automatic Dependent Surveillance–Broadcast (ADS-B) system using Deep Graph Convolution and Generative model (GA-GAN)

    University essay from Linköpings universitet/Databas och informationsteknik

    Author : Jayesh Kenaudekar; [2022]
    Keywords : Intrusion detection aircraft aviation security adsb protocol AI deep learning machine learning graph generative model surveillance broadcast;

    Abstract : The Automatic Dependent Surveillance-Broadcast (ADS-B) is a key component of the Next Generation Air Transportation System (Next Gen) that manages the increasingly congested airspace and operation. From Jan 2020, the U.S. Federal Aviation Administration (FAA) mandated the use of (ADS-B) as a key component of Next Gen project. READ MORE

  4. 23. Localization of Combat Aircraft at High Altitude using Visual Odometry

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jenny Nilsson Boij; [2022]
    Keywords : Monocular Visual Odometry; Monocular SLAM; High Altitude; Combat Aircraft; X-Plane;

    Abstract : Most of the navigation systems used in today’s aircraft rely on Global Navigation Satellite Systems (GNSS). However, GNSS is not fully reliable. For example, it can be jammed by attacks on the space or ground segments of the system or denied at inaccessible areas. READ MORE

  5. 24. Autonomous Landing of an Unmanned Aerial Vehicle on an Unmanned Ground Vehicle using Model Predictive Control

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Emil Boström; Erik Börjesson; [2022]
    Keywords : Model predictive control; MPC; Unmanned aerial vehicle; UAV; Unmanned ground vehicle; UGV; Path planning; Vehicle dynamics; Autonomous systems; Autonomous landing; Quadcopter; Gazebo; ROS;

    Abstract : The research on autonomous vehicles, and more specifically cooperation between autonomous vehicles, has become a prominent research field during the last cou- ple of decades. One example is the combination of an unmanned aerial vehicle (UAV) together with an unmanned ground vehicle (UGV). READ MORE

  6. 25. A Modular Approach to Design and Implementation of an Active GNSS Antenna

    University essay from Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska fakulteten

    Author : Ulrik Hecktor; [2022]
    Keywords : GNSS; RTK; circular patch antenna; LNA; stacked patch antenna;

    Abstract : This master’s thesis describes the design, implementation and testing of an active antenna intended for use with global navigation satellite systems. The active antenna is composed of two major parts, a dual-band circular patch antenna and a dual-band low-noise amplifier. To streamline the design process, a modular solution was adopted. READ MORE
