  1. 1. 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

  3. 2. Primary Drivers of Sea Level Variability in the North – Baltic Sea Transition Using Machine Learning

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :David Ek; [2023-01-09]
    Nyckelord :;

    Sammanfattning : Global mean sea level is rising, however not uniformly. Regional deviations of sea surface height (SSH) are common due to local drivers, including surface winds, ocean density stratifications, vertical land- & crustal movements and more. LÄS MER

  4. 3. Design of a 2-D Lattice Flower Constellation for Earth observation applying the twin satellite concept

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

    Författare :Julia Martín-Fuertes Brañas; [2023]
    Nyckelord :2D Lattice Flower Constellation design; number of satellites; number of planes; revisit time; coverage; optimized constellation; target list; twin satellite concept; FreeFlyer; 2D Lattice Flower Constellation design; antal satelliter; antal plan; återbesökstid; täckning; optimerad konstellation; mållista; tvilling-satellit-koncept; FreeFlyer;

    Sammanfattning : Events such as forest fires or floods are a danger to our Earth’s environment and the people living in it. The sooner they can be detected, the less damage they can cause. An idea arises: use satellites to monitor the Earth and relay information to prevention and rescue organizations in a very short time, regardless of accessibility from ground. LÄS MER

  5. 4. Investigation of Antenna Radomes in Low Earth Orbits

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Mathias Manohar Gren; [2023]
    Nyckelord :Materials; Science; Space; Satellites; Antenna Radomes; Beyond Gravity; Coatings; Physics; Chemistry; Low Earth Orbits; Engineering; Lunds University; Materials Chemistry; Technology and Engineering;

    Sammanfattning : Introduction: This master’s thesis focuses on exploring improved alternative material solutions for antenna radomes used to protect Beyond Gravity Sweden’s satellite antennas in low Earth orbits. Background: As the environment in low Earth orbit is harsh, surface materials on satellites experience high levels of atomic oxygen, ultra violet radiation, thermal-fluctuation, charged particles and micro meteoroids.

  7. 5. Temporal Projections of the Shoreline Displacement on Gotland

    Kandidat-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Yonathan Tekeste; [2023]
    Nyckelord :Sea Level Rise; Shoreline Displacement; Gotland;

    Sammanfattning : Global mean sea level rise (GMSLR) impacts the displacement of the world’s coasts and shorelinedifferently due to it being contingent on local topographic and geological conditions. The island of Gotlandis located in the Fennoscandian Shield which lies at the intersection between GMSLR and post-glacialrebound (PGR), at rates that vary latitudinally and, in some areas, are at equal levels.
