Detection of ionospheric signatures from GPS-derived total electron content maps [PDF]
Journal of Geodetic Science, 2014 The processing of measurement data from satelliteconstellations such as Global Navigation Satellite Systems(GNSS), including the well-known Global PositioningSystem (GPS), have been successfully applied to virtuallyall areas of geophysical sciences.

Traveling wave packets of total electron content disturbances as deduced from global GPS network data [PDF]
, 2003 We identified a new class of mid-latitude medium-scale traveling ionospheric disturbances (MS TIDs), viz. traveling wave packets (TWPs) of total electron content (TEC) disturbances.

Total Electron Content Estimation with Reg‐Est [PDF]
Journal of Geophysical Research: Space Physics, 2007 Total Electron Content (TEC) constitutes one of the key elements for observing the variable structure of the ionosphere. GPS provides a cost‐effective alternative in TEC estimation through earth‐based receivers. In this paper, one of the TEC estimation methods, namely Reg‐Est, is investigated in detail in terms of its parameters and developed further ...
