• A new hybrid method to improve the ultra-short-term prediction of LOD 

      Modiri, Sadegh; Belda, Santiago; Hoseini, Mostafa; Heinkelmann, Robert; Ferrandiz, Jose M; Schuh, Harald (Peer reviewed; Journal article, 2020)
      Accurate, short-term predictions of Earth orientation parameters (EOP) are needed for many real-time applications including precise tracking and navigation of interplanetary spacecraft, climate forecasting, and disaster ...
    • Polar motion prediction using the combination of SSA and Copula-based analysis 

      Modiri, Sadegh; Belda, Santiago; Heinkelmann, Robert; Hoseini, Mostafa; Ferrandiz, Jose M; Schuh, Harald (Journal article; Peer reviewed, 2018)
      The real-time estimation of polar motion (PM) is needed for the navigation of Earth satellite and interplanetary spacecraft. However, it is impossible to have real-time information due to the complexity of the measurement ...
    • Towards understanding the interconnection between celestial pole motion and earth’s magnetic field using space geodetic techniques 

      Modiri, Sadegh; Heinkelmann, Robert; Belda, Santiago; Malkin, Zinovy; Hoseini, Mostafa; Korte, Monika; Ferrándiz, José M.; Schuh, Harald (Peer reviewed; Journal article, 2021)
      The understanding of forced temporal variations in celestial pole motion (CPM) could bring us significantly closer to meeting the accuracy goals pursued by the Global Geodetic Observing System (GGOS) of the International ...
