  1. 1. Compact Digital Track Maps: Enhancing Train Traveller Information at the Crossing of Accuracy and Availability : A comparative analysis of algorithms for generating compact representations of railway tracks

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Adam Andersson; [2023]
    Nyckelord :Train positioning; Digital track map; Digital map generation; Position measurement; Global navigation satellite system; Cartography; Tågpositionering; Digitala spårkartor; Generering av digitala kartor; Positionsmätning; Satellitnavigation; Kartograf;

    Sammanfattning : Trains are constrained to the railway tracks they operate on. This can be leveraged for absolute train positioning, where a train’s position can be mapped onto a digital track map (DTM). Extensive research has been dedicated to enhancing the accuracy of DTMs. LÄS MER

  3. 2. Development of a Deep-space-capable Navigation System for the Hugin Space Exploration Technology Demonstration Satellite Mission

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Axel Widenfelt; [2021]
    Nyckelord :Autonomous optical navigation; Autonom optisk navigering;

    Sammanfattning : Development of autonomous in-fight navigation capability for a CubeSat mission is a challenging task, often ignored in favour of relying on a Global Navigation Satellite System (GNSS). However, the potential value in solving this problem becomes great for deep-space missions where such networks have limited coverage. LÄS MER

  4. 3. Relative Localization using Satellite positioning

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Karl Lundin; [2020]
    Nyckelord :;

    Sammanfattning : In this thesis, the basis for Global Navigation Satellite Systems (GNSS) ispresented and a comparison between the expected precision of the relative po-sition between two receivers is presented based on observations made by twostationary receivers. The positioning is compared between the solution fromtwo algorithms. LÄS MER

  5. 4. Development of GNSS Guidelines for Cadastral Surveying in Botswana : Challenges and Potentials

    Kandidat-uppsats, Högskolan i Gävle/Samhällsbyggnad, GIS

    Författare :Anton Henriksson; Elias Ekman; [2017]
    Nyckelord :GNSS; Cadastral Surveying; Cadastre; Guidelines; Botswana.;

    Sammanfattning : In recent years a Continuously Operating Reference Stations (CORS)-network of more than 50 reference stations (with more on the way) have been set up extending over the whole southern African country of Botswana. This has opened up for new and improved possibilities of implementing the Global Navigation Satellite System (GNSS) technique in surveying practice. LÄS MER
