  • Detection and description of the different ionospheric disturbances that appeared during the solar eclipse of 21 August 2017 

    Yang, Heng; Monte Moreno, Enrique; Hernández Pajares, Manuel (Multidisciplinary Digital Publishing Institute (MDPI), 2018-10-30)
    Article
    Open Access
    This work will provide a detailed characterization of the travelling ionospheric disturbances (TIDs) created by the solar eclipse of 21 August 2017, the shadow of which crossed the United States from the Pacific to the ...
  • Direct MSTID mitigation in precise GPS processing 

    Hernández Pajares, Manuel; Wielgosz, Pawel; Paziewski, Jacek; Krypiak-Gregorczyk, Anna; Krukowska, Marta; Stepniak, Katarzyna; Kaplon, Jan; Hadas, Tomasz; Sosnica, Krzysztof; Bosy, Jaroslaw; Orús Pérez, Raul; Monte Moreno, Enrique; Yang, Heng; García Rigo, Alberto; Olivares Pulido, Germán (2017-03)
    Article
    Open Access
    In this paper, the authors summarize a simple and efficient approach developed to mitigate the problem in precise GNSS positioning originated by the most frequent ionospheric wave signatures: the Medium Scale Travelling ...

  • Internal report. Numerical methods for medium scale traveling ionospheric disturbances signal pre-processing 

    Yang, Heng; Monte Moreno, Enrique; Hernández Pajares, Manuel (2015-01-15)
    External research report
    Open Access
    In this paper we discuss the e ects of several signal preprocessing methods for enhancing the Medium Scale Traveling Ionospheric Dis- turbances (MSTIDs) signal. The MSTIDs signal are the ionospheric signatures of waves ...
  • Internal report. Solving mixed integer non-linear programming problem applied to GNSS data 

    Yang, Heng; Monte Moreno, Enrique; Hernández Pajares, Manuel (2014-11-07)
    External research report
    Open Access
    The purpose of this paper is to characterize Medium Scale Trav- eling Ionospheric Disturbances (MSTIDs), by means of Mixed Integer Nonlinear Programming (MINLP). The MINLP techniques are used to for estimating the ...
  • Internal report. Spectral methods for time delay estimation of MSTIDs signal 

    Yang, Heng; Monte Moreno, Enrique; Hernández Pajares, Manuel (2015-02-14)
    External research report
    Open Access
    The primary goal of this work is to summarize spectral meth- ods to estimate the time delay variations of the detrended Medium Scale Traveling Ionospheric Disturbances (MSTIDs) signals and pre- liminarily discuss the ...
  • Interpretación de un experimento de transporte de solutos con reacciones bimoleculares irreversibles utilizando un modelo de transferencia de masa 

    Yang, Heng (Universitat Politècnica de Catalunya, 2015-05)
    Master thesis
    Restricted access - author's decision
    El transporte de soluto reactivo en medio poroso es caracterizado por una combinación de procesos físico - químicos. Esto ocurre en una multiplicidad de escalas espaciotemporales que deben ...
  • Multi-TID detection and characterization in a dense Global Navigation Satellite System receiver network 

    Yang, Heng; Monte Moreno, Enrique; Hernández Pajares, Manuel (2017-09-01)
    Article
    Open Access
    The medium-scale traveling ionospheric disturbances (MSTIDs) constitute the most frequent ionospheric wave signatures. We propose a method for detecting the number of simultaneous MSTIDs from a time series of high-pass-filtered ...
  • TEC forecasting based on manifold trajectories 

    Monte Moreno, Enrique; García Rigo, Alberto; Hernández Pajares, Manuel; Yang, Heng (Multidisciplinary Digital Publishing Institute (MDPI), 2018-06-22)
    Article
    Open Access
    In this paper, we present a method for forecasting the ionospheric Total Electron Content (TEC) distribution from the International GNSS Service’s Global Ionospheric Maps. The forecasting system gives an estimation of the ...
