  1. 1. SMOS satellite hardware anomaly prediction methods based on Earth radiation environment data sets

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Aleksi Walden; [2016]
    Nyckelord :SMOS; Soil Moisture and Ocean Salinity; satellite; MIRAS; Microwave Imaging Radiometer with Aperture Synthesis; ESAC; hardware anomaly; prediction; radiation environment;

    Sammanfattning : SMOS (Soil Moisture and Ocean Salinity) is ESA's Earth Explorer series satellite carrying the novel MIRAS (Microwave Imaging Radiometer with Aperture Synthesis) interferometric synthetic aperture radar. Its objective is monitoring and studying the planet's water cycle by following the changes in soil moisture levels and ocean surface salt concentrations on a global scale. LÄS MER

    Sammanfattning : Synthetic Aperture Radar (SAR) is an emerging technique in remote sensing. The technology is capable of producing high-resolution images of the earth surface in all-weather conditions. LÄS MER

  7. 5. Long-term Stability Analysis of Antenna Temperature & Brightness Temperature from ESA's SMOS Satellite

    Master-uppsats, KTH/Geodesi och geoinformatik

    Författare :Lotta Rehn-Molin; [2011]
    Nyckelord :;

    Sammanfattning : The European Space Agency’s Soil Moisture and Ocean Salinity (SMOS) satellite is designed to accurately detect the energy of the electromagnetic radiation naturally emitted from Earth, from which the level of soil moisture and ocean salinity content can be derived. Studies of these two geophysical parameters will increase the knowledge of the Earth’s water cycle and improve the understanding of the climate. LÄS MER
