  1. 1. Robust Aircraft Positioning using Signals of Opportunity with Direction of Arrival

    University essay from Linköpings universitet/Reglerteknik

    Author : Erik Axelsson; Sebastian Fagerstedt; [2023]
    Keywords : Simultaneous localisation and mapping; direction of arrival; signals of opportunity; extended Kalman filter; positioning;

    Abstract : This thesis considers the problem of using signals of opportunity (SOO) with known direction of arrival (DOA) for aircraft positioning. SOO is a collective name for a wide range of signals not intended for navigation but which can be intercepted by the radar warning system on an aircraft. READ MORE

  2. 2. Collaborative Mapping with Drone Swarms Utilizing Relative Distance Measurements

    University essay from Linköpings universitet/Reglerteknik

    Author : Johan Forsman; Carl Tidén; [2023]
    Keywords : ;

    Abstract : The field of use for unmanned aerial vehicles, UAVs, has completely exploded in the last decade. Today they are used for surveillance missions and inspecting places that are difficult for people to access. To increase the efficiency and robustness in the execution of these types of missions, swarms of cooperating drones can be used. READ MORE

  3. 3. Status Mapping of tank to grave management of Low-GWP refrigerants.

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Sandra Parra Gimeno; [2023]
    Keywords : Refrigerant; Blends; Synthetic low-GWP refrigerant; Natural refrigerant; Global Warming Potential GWP ; Tank-to-grave; Interviews.; Köldmedier; Blandning; Globalt uppvärmningspotential GWP ; Låg-GWP köldmedier; Naturligt köldmedier; installation till destruktion; Intervjuer.;

    Abstract : Refrigeration plays a vital role today in various residential, commercial, and industrial processes, requiring refrigerants to facilitate the cooling or heating processes. Over time, refrigerants have undergone significant changes to meet technological, social, environmental, and economic needs. READ MORE

  4. 4. Robust light source detection for AUV docking

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Joar Edlund; [2023]
    Keywords : Autonomous Underwater Vehicle; Docking; Detection; Poseestimation; Visual Navigation; Autonoma Undervattensfordon; Dockning; Detektering; Positionsestimering; Visuell Navigation;

    Abstract : For Autonomous Underwater Vehicles (AUVs) to be able to conduct longterm surveys, the ability to return to a docking station for maintenance and recharging is crucial. A dynamic docking system where a slowly moving submarine acts as the docking station provides increased hydrodynamic control and reduces the impact of environmental disturbances. READ MORE

  5. 5. Validating and comparing Total Electron Content estimates from Incoherent Scatter Radar and Global Positioning System

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Sven Molenkamp; [2023]
    Keywords : ;

    Abstract : This thesis aims to analyze the possibilities to use Incoherent Scatter Radar to measure Total Electron Content in the ionosphere. By comparing the results from EISCATselectron density data over altitude and time to Total Electron Content estimates from GPS satellites and their receivers through a climatology as well as qualitative analysis for separate EISCAT experiments a comparison between the two is conducted.
