    • Assessment of the capabilities and applicability of ionospheric perturbation indices provided in Europe 

      Borries, Claudia; Wilken, Volken; Jacobsen, Knut Stanley; García Rigo, Alberto; Dziak-Jankowska, Beata; Kervalishvili, Guram; Jakowski, Norbert; Tsagouri, Ioanna; Hernández Pajares, Manuel; Ferreira, Arthur A.; Hoque, Mainul (2020-08-01)
      Article
      Open Access
      Perturbations in the ionosphere are of great interest not only for scientific research, but also for applications using transionospheric radiosignals (e.g. GNSS applications and HF communication), because the transmission ...
    • Comparative testing of four ionospheric models driven with GPS measurements 

      Zandbergen, R.; Feltens, Joachim; Angling, M; Jackson Booth, N; Jakowski, Norbert; Hoque, Mainul; Hernández Pajares, Manuel; Aragón Ángel, María Ángeles; Orús Pérez, Raül (2011-07-28)
      Article
      Open Access
      In the context of the European Space Agency/European Space Operations Centre funded Study “GNSS Contribution to Next Generation Global Ionospheric Monitoring,” four ionospheric models based on GNSS data (the Electron ...
    • Ionosphere monitoring and forecast activities within the IAG working group “Ionosphere Prediction” 

      Hoque, Mainul; García Rigo, Alberto; Erdogan, Eren; Cueto, M.; Jakowski, Norbert; Berdermann, Jens; Hernández Pajares, Manuel; Schmidt, Michael; Wilken, Volken (2017)
      Conference lecture
      Open Access
      Ionospheric disturbances can affect technologies in space and on Earth disrupting satellite and airline operations, communications networks, navigation systems. As the world becomes ever more dependent on these technologies, ...
    • Ionospheric tomography by gradient-enhanced kriging with STEC measurements and ionosonde characteristics 

      Minkwitz, David; van den Boogaart, K. Gerald; Gerzen, Tatjana; Hoque, Mainul; Hernández Pajares, Manuel (2016-11-14)
      Article
      Open Access
      The estimation of the ionospheric electron density by kriging is based on the optimization of a parametric measurement covariance model. First, the extension of kriging with slant total electron content (STEC) measurements ...
    • Recent activities of IAG working group “Ionosphere Prediction” 

      Erdogan, Eren; Hoque, Mainul; García Rigo, Alberto; Cueto, M.; Schmidt, Michael; Jakowski, Norbert; Berdermann, Jens; Monte Moreno, Enrique; Hernández Pajares, Manuel (2018)
      Conference lecture
      Open Access
      Ionospheric disturbances pose, for instance, an increasing risk on economy, national security, satellite and airline operations, communications networks and the navigation systems. Constructing ...
