    The ionosphere impacts radio-wave propagation, notably up to a few GHz. The main applications impacted by the ionosphere are GNSS positioning and timing, Earth Observations (especially low frequency SAR missions e.g. ...
  • Interferometry based orbit observation for geosynchronous synthetic aperture radar (GEOSAR) missions 

    Nicolás Álvarez, Jorge; Carreño Megias, Xavier; Fusté i Lara, Oriol; Aguasca Solé, Alberto; Broquetas Ibars, Antoni (International Astronautical Federation, 2019)
    Conference report
    Restricted access - publisher's policy
    A major limitation of current Low Earth Orbit Synthetic Aperture Radars (LEOSAR) is related to their revisit time of several days or weeks. They cannot provide continuous monitoring over the same area of the planet. The ...
