• Determination of differential code biases with multi-GNSS observations (2016, methodology): “GPS and GLONASS DCBs routinely estimated by individual Ionospheric Associate Analysis Center (IAAC, including CODE, JPL, UPC, and ESA) of the IGS are currently considered as the most reliable DCB products (Hernández-Pajares et al. 2009; Dach et al. 2009; Li et al. 2015b).”
• Differential Code Bias Estimation using Multi‐GNSS Observations and Global Ionosphere Maps (2014, background): “In the most simple case of a single-layer model ([12], [9]), the ionosphere is considered as a thin shell of constant altitude h (Fig.”
• Ionospheric response to the 2015 St. Patrick's Day storm: A global multi‐instrumental overview (2015, background): “However, it is known that in the GIM the error in the VTEC estimation can be quite significant under certain circumstances, especially over the oceans, where only a few ground-based GPS receivers are located [e.g., Hernandez-Pajares et al., 2009].”
• SHPTS: towards a new method for generating precise global ionospheric TEC map based on spherical harmonic and generalized trigonometric series functions (2015, methodology): “…and Universitat Politècnica de Catalunya/IonSAT (UPC, Barcelona, Spain), began to independently compute the global ionospheric TEC map (GIM) on a daily basis, and submit the results to the corresponding IGS combination center to generate the final GIM (Feltens 2003; Hernández-Pajares et al. 2009).”
• Microarcsecond Radio Astrometry (2013, methodology): “Hernández-Pajares et al. (2009) compared TEC values obtained by GPS and direct measurements (such as with JASON and TOPEX) and found vertical Radio Astrometry 27 TEC values among the methods differ at the ≈ 20% level.”
