    • A preliminary study on ionospheric scintillation anomalies detected using GNSS-R data from NASA CYGNSS mission as possible earthquake precursors 

      Molina Ordóñez, Carlos; Boudriki Semlali, Badr Eddine; Hyuk, Park; Camps Carmona, Adriano José (Multidisciplinary Digital Publishing Institute (MDPI), 2022-05-26)
      Article
      Open Access
      Ionospheric perturbations affect the propagation of electromagnetic waves. These perturbations, besides being a problem for space communications, satellite navigation, and Earth observation techniques, could also be used ...

    • Design and implementation of a single On-Board Computer for CubeSats 

      Molina Ordóñez, Carlos (Universitat Politècnica de Catalunya, 2019-09)
      Master thesis
      Open Access
      his document reports the process of design, implementation, and testing of an On-Board Computer for CubeSats in a single 1U-sized CubeSat PCB. The aim is to design a modular, cheap, e cient and exible product than could ...

    • First evidences of ionospheric plasma depletions observations using GNSS-R data from CYGNSS 

      Molina Ordóñez, Carlos; Camps Carmona, Adriano José (Multidisciplinary Digital Publishing Institute (MDPI), 2020-11-02)
      Article
      Open Access
      At some frequencies, Earth’s ionosphere may significantly impact satellite communications, Global Navigation Satellite Systems (GNSS) positioning, and Earth Observation measurements. Due to the temporal and spatial variations ...

    • Ionospheric scintillation anomalies associated with the 2021 La Palma volcanic eruption detected with Gnss-R and Gnss-Ro observations 

      Molina Ordóñez, Carlos; Boudriki Semlali, Badr Eddine; González Casado, Guillermo; Hyuk, Park; Camps Carmona, Adriano José (Institute of Electrical and Electronics Engineers (IEEE), 2022)
      Conference report

      Recent studies have shown possible signatures or precursors of seismic activity in the ionosphere. Our group is focusing on ionospheric scintillation associated with seismic activity. By the time this study was conducted, ...

    • Ionospheric signal propagation simulator for earth observation missions 

      Fernández Niño, Elena; Molina Ordóñez, Carlos; Camps Carmona, Adriano José (Institute of Electrical and Electronics Engineers (IEEE), 2022)
      Conference report
      Open Access
      Following the discovery of the ionosphere by Marconi in 1901, different disciplines have been influenced from the ionospheric effects on radio-waves, such as communications or Earth Observation missions. The ionosphere ...

    • Possible evidence of earthquake precursors observed in ionospheric scintillation events observed from spaceborne GNSS-R data 

      Molina Ordóñez, Carlos; Boudriki Semlali, Badr Eddine; Hyuk, Park; Camps Carmona, Adriano José (Institute of Electrical and Electronics Engineers (IEEE), 2021)
      Conference report
      Open Access
      Several factors may induce perturbations on the ionospheric plasma, changing its average electron density and creating small-scale irregularities, changing its shape and altitude. Solar irradiance and space weather are ...

    • Study of land surface temperature anomalies associated to earthquakes using GOES data 

      Boudriki Semlali, Badr Eddine; Molina Ordóñez, Carlos; Hyuk, Park; Camps Carmona, Adriano José (Institute of Electrical and Electronics Engineers (IEEE), 2022)
      Conference lecture
      Restricted access - publisher's policy
      Annually, earthquakes cause human and material losses. For instance, between 1998 and 2018, 846 thousand deaths and about US$ 661 billion of economic losses were recorded due to earthquakes. Currently, there is no clear ...
