  1. 1. Characterization of Lamps of IRF Solar Simulator

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Mrunmayee Sonna; [2023]
    Nyckelord :IRF; Solar simulator; Characterization; Thermal simulations; Systema-Thermica; Autodesk Inventor; correlated results;

    Sammanfattning : The Swedish Institute of Space Physics (IRF) at Kiruna focuses on research activities in the ionosphere, magnetosphere, and upper atmosphere of the planet as well as the development and production of various sensors and detectors for space research. The test facility includes the IRF SpaceLab which is equipped with multiple testing equipment. LÄS MER

  3. 2. Definition and evaluation of a system for measuring local geomagnetic variations : Autonomous station for magnetic measurements

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

    Författare :Viktor Olsson; [2023]
    Nyckelord :Local Geomagnetic Variations; Fluxgate Magnetometer; Space Weather; Solar Wind; Magnetic Measurements; Variometer; Solar Activity.; Lokala geomagnetiska variationer; Fluxgate-Magnetometer; Rymdväder; Solvinden; Magnetiska Mätningar; Variometer; Solaktivitet.;

    Sammanfattning : Earth is under constant influence of the Sun and phenomena driven by the solar wind that may affect man-made technology. These events are summarized under the concept of space weather. This creates variations in Earth’s magnetic field and nearby space. Space weather can affect power grids, gas pipelines and also have effects on human health. LÄS MER

  4. 3. Nowcasting the IRF Auroral Index with Recurrent Neural Networks

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Per Danielsson; [2022]
    Nyckelord :Aurora borealis; aurora; neural networks; artificial intelligence; machine learning; recurrent;

    Sammanfattning : There is a long history in Kiruna of conducting research on the physics of the aurora borealis. There is also a long history of providing tourists with great opportunities to see the auroras. Planning such tourist activities can be challenging since the auroras are hard to predict. LÄS MER

  5. 4. Spatial Variability in the Ionosphere and GNSS Signal Delays in the L-band: A Direct Comparison of In-Situ Satellite- and Swepos-Data

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Författare :Oscar Suneson; [2021]
    Nyckelord :fysik; jonosfären; GNSS; GPS; astrofysik; navigationssystem; mätteknik;

    Sammanfattning : It has been shown that ionospheric irregularities can disturb our GNSS (Global Navigation Satellite System) communication. This disturbance is caused by scintillation of the radio signals when they pass through the ionosphere, leading to lock-on difficulties or in worst case, a loss of position for the GNSS-receiver.

  7. 5. Towards a Climatology of Polar Stratospheric Cloudsbased on observation with the IRF lidar

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Oliver Willbrink; [2021]
    Nyckelord :;

    Sammanfattning : The effect that the Polar stratospheric clouds (PSCs) have on the destruction of ozone in the polar vortex is well known. The study of these clouds is therefore highly relevant and important. A tool that can be used to gather parameters needed to describe the PSC is a lidar (Light Detection and Ranging). LÄS MER
