  1. 6. Satellite signal attenuation due to atmospheric influences in northern Sweden

    University essay from Umeå universitet/Institutionen för fysik

    Author : Adrian Stigsson; [2024]
    Keywords : ;

    Abstract : Earth-space traversing electromagnetic waves become attenuated as they propagate through the atmosphere. The sources of attenuation are weather phenomena in the Troposphere, and scintillation and absorption in the Ionosphere. READ MORE

  3. 7. Planet-NeRF : Neural Radiance Fields for 3D Reconstruction on Satellite Imagery in Season Changing Environments

    University essay from Linköpings universitet/Datorseende

    Author : Erica Ingerstad; Liv Kåreborn; [2024]
    Keywords : NeRF; Neural Radiance Field; Satellite Imagery; Machine Learning; Deep Learning;

    Abstract : This thesis investigates the seasonal predictive capabilities of Neural Radiance Fields (NeRF) applied to satellite images. Focusing on the utilization of satellite data, the study explores how Sat-NeRF, a novel approach in computer vision, per- forms in predicting seasonal variations across different months. READ MORE

  4. 8. Real-Time Navigation for Swarms of Synthetic Aperture Radar (SAR) Satellites

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Antoni Eritja Olivella; [2024]
    Keywords : SAR; Real-time orbit determination; Real-time baseline determination; swarms; satellite; formation flying;

    Abstract : The pursuit of precision and flexibility in satellite missions has led to an increased number of formation flying missions being developed. These systems consist of multiple satellites flying at close distances (from a few kilometres to a few meters) to achieve common objectives. READ MORE

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

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

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

    Abstract : 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. READ MORE

  6. 10. CHANGES IN URBAN GREENERY DURING THE 2018 HEAT WAVE – A CASE STUDY FOR GÖTEBORG USING REMOTE SENSING

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Ivan Ruzic; [2023-06-21]
    Keywords : heat wave; urban trees; NDVI; remote sensing;

    Abstract : Urban vegetation plays a crucial role in diverse urban microclimates. The numerous ecosystem services provided by vegetation, particularly trees, ensure greater quality of life and thermal comfort regulation. Yet, not all trees are immune to extreme weather events, such as droughts and heat waves, especially in cities. READ MORE
