Spectra of equatorial total electron content derived from GPS signals
High cadence GPS TEC signals collected on Ascension Island, South Atlantic Ocean, during sunspot minimum, and in Vanimo, Papua New Guinea, over half a solar cycle, have been analysed for their spectral properties. A new parameter Tk has been introduced to quantify the strength of TEC irregularities...
