  1. 1. Ageing process analysis of solar panels in graveyard geostationaryorbit for reusability potential

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Robin Drevet; [2024]
    Nyckelord :space debris; Spacecraft Materials; satellite; Space Sustainability; Space Circularity; Space Manufacturing;

    Sammanfattning : The constant growth of space debris and the associated risks force the space community to find solutions to mitigate them. Today the most advanced solutions to dispose of satellites and rocket stages after the end of mission consists of moving them either into a graveyard orbit or towards an atmospheric re-entry ending in the demise of both spacecraft and its materials.

  3. 2. Mätningar av internetkapacitet, tillförlitlighet och fördröjning i ett Stockholmsbaserat Starlink-system : En undersökning av hur satellitinternet kan bidra till att ökateckningsgrad i Sverige

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Niclas Höglund; [2024]
    Nyckelord :Starlink; LEO; wireless; satellite; internet; ground stations; tele operators; Ku -band; Ka-band; Starlink; LEO; trådlös; satellit; internet; markstationer; teleoperatörer; Ku -bandet; Ka-bandet;

    Sammanfattning : Det är mycket dyrt att utveckla markinfrastruktur för att försörja hela jorden med internet. Detta ärspeciellt fallet i glesbebyggda områden då det finns lite ekonomisk vinning. Sverige som är ett stortoch glesbefolkat land har stora områden av denna typ. LÄS MER

  4. 3. Using GIS and satellite data to assess access of green area for children living in growing cities

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Rebecca Borg; [2024]
    Nyckelord :Geography; GIS; Geographical Information System; Urban green space; children; schools; Malmö; Earth and Environmental Sciences;

    Sammanfattning : Urban green space (UGS) refers to open spaces within an urban context that are filled with greenery and nature. These can range from very small vegetation to expansive park areas. The common denominator is that they have proven to be beneficial for human health and well-being. Access to green spaces is also important for children. LÄS MER

  5. 4. Hyperspectral and multispectral satellite data analysis of nitrogen in grazed and ungrazed tundra in Långfjället, Sweden

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Emma Dahlstedt; [2023-08-18]
    Nyckelord :Hyperspectral imaging; Imaging spectroscopy; Nitrogen; Reindeer; Herbivory; Tundra; Grazing;

    Sammanfattning : Reindeer are a keystone species in the circumpolar north, where they hold great cultural and ecological importance. Continued climate change threatens the long-term sustainability of reindeer husbandry. Reindeer can affect the tundra landscape, influencing the soil nutrient cycling, including the soil nitrogen availability. LÄS MER

  7. 5. Implementing Total Electron Content in the Grand Unifed Incoherent Scattering Design and Analysis Program for Investigation of Causes to Scintillations

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Samuel Sonesson; [2023]
    Nyckelord :Total Electron Content; Scintillation; Incoherent Scattering; Ionosphere;

    Sammanfattning : Functionality for calculating and plotting diferent Total Electron Content (TEC) measurements such as Slant Total Electron Content (sTEC), error in sTEC, and VerticalTotal Electron Content (vTEC) was implemented into the data analysis program fromEuropean Incoherent Scattering Scientifc Association (EISCAT), the Grand Unifed Incoherent Scattering Design and Analysis Program (GUISDAP). This utilises a thin-singlelayer model of the ionosphere to convert sTEC into the more analytically useful vTEC. LÄS MER
