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

    Master-uppsats, Linköpings universitet/Reglerteknik

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

    Sammanfattning : 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. LÄS MER

  3. 2. Design and Implementation of a Rocket Launcher Hybrid Navigation

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Omar Ugolini; [2023]
    Nyckelord :launch vehicle navigation; delayed Kalman filter; strapdown; navigering av bärraketer; fördröjt Kalman-filter; strapdown;

    Sammanfattning : Rocket Factory Augsburg (RFA) a German New Space Startup is developing a three-stage rocket launcher aiming at LEO/SSO orbits. A fundamental responsibility of the GNC team is the development of the rocket navigation algorithm to estimate the attitude, position, and velocity allowing the guidance and control loops to autonomously steer the rocket.

  4. 3. Incorporation of GNSS system for underwater cleaning robot

    M1-uppsats, KTH/Produktionsutveckling

    Författare :David Blomkvist; [2023]
    Nyckelord :GPS; underwater cleaning robot; autonomous; GPS; poolrobot; autonom;

    Sammanfattning : Water reservoirs, such as swimming pools, are usually cleaned using underwater cleaners, also called pool robots. These robots usually use a randomized pattern to cover the bottom areas. For large and/or complex bottoms, a randomized cleaning pattern may be ineffective. LÄS MER

  5. 4. Real Time Navigation Algorithms for LEO Small Satellites using COTS GNSS

    Master-uppsats, KTH/Lantmäteri – fastighetsvetenskap och geodesi

    Författare :Nathan Groisne; [2023]
    Nyckelord :PNT; Small Satellite; COTS; GNSS; Navigation; ACS; PNT; små satelliter; COTS; GNSS; navigering; ACS;

    Sammanfattning : Many satellites in LEO use a GNSS-based navigation system, taking advantage of the GNSS constellations in MEO to enhance navigation capabilities. The thesis work focused on developing the software enabling GNSS-based navigation for Hemeria's future small satellites operating in LEO. LÄS MER

  7. 5. Road Condition Analysis For Autonomous Haulers

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Karl Söderlund; Simon Friberg; [2023]
    Nyckelord :;

    Sammanfattning : With autonomous vehicles becoming more common and established, there are some problems to overcome before their full potential can be reached. One of these problems is the lack of information about the condition of the road, which traditionally would be acquired from the driver operating the vehicle. LÄS MER
