“…To complete consideration of the obtained results, we note another important feature of the TEC behavior, at which attention was paid in [24]. We mean the generation of plasma-density disturbances with frequency multiple of the modulation frequency of the high-power radio wave.…”

“…As was mentioned in [24], the appearance of odd (third and fifths) harmonics of the main periodic in the recorded-signal spectrum can be determined by the radiation spectrum of the high-power radio wave when amplitude modulation of the symmetric meander type, for which the radiation duration is equal to the pause duration, is employed. However, the second harmonic, which is often detected in the experiment, is absent in the spectrum of such a signal.…”

“…The appearance of a periodic with θ ≈ 7-9 min is seen beginning with 12:25-12:45 UT. The possible mechanism of the appearance of harmonics of the main periodic is discussed in [24], where odd harmonics (in this case, the harmonics with θ ≈ 3 min and θ ≈ 2 min) are associated with the radiation spectrum of the highpower radio wave during its amplitude modulation of meander type. However, the second harmonic with θ ≈ 5 min, which is recorded in the received-signal spectrum is absent in the symmetric meander spectrum ((+5 min; −5 min) in this case).…”

We present the results of experimental studies of the properties of the plasma-density disturbances created during heating of the ionospheric F 2 region by high-power HF radio waves radiated by the "Sura" heating facility (Radiophysical Research Institute, Nizhny Novgorod). These experiments are specific in that they were performed in a sunlit (daytime) ionosphere when the generation of ionospheric turbulence has specific features and the turbulence intensity level is low enough. The plasma-density disturbances induced by high-power HF radio emission were sounded by signals of the GPS satellites, the line of sight to which crossed different parts of the disturbed ionosphere region. Threshold powers of the excitation of artificial plasma-density variations as well as spatial, temporal, spectral, and energy characteristics of the generated disturbances are determined.

“…It is seen that at the moment of the event the relative TEC abruptly increases by ~1.5 TECU, while its derivative exhibits the fine structure with three maxima, which is associated with the variations in the ionizing flux produced by the flare. Based on TEC variations it is possible also to study the characteristics of artificial ionospheric perturbations including TEC perturbations caused by ionospheric heating [7]. Presented in Figure 9 are the results obtained in the experiments on heating the midlatitude dayside ionosphere by the Sura facility on March 18, 2009.…”

We present the results of application high-orbital (GPS/GLONASS) and low-orbital (Parus/TRANSIT) satellite navigation systems to the study of different-scale irregularities in the ionospheric total electron content (TEC), such as troughs, crests of equatorial anomaly, traveling ionospheric disturbances and so on. We also present the results of the comparison of the global ionospheric maps (GIM) of vertical TEC, which are now widely used in ionospheric research, with the results of low-and high-orbital radio tomographic ionospheric imaging and with the data of UV spectral imaging form GUVI instrument (Global Ultraviolet Imager). The data from low-orbital radiotomography systems in Russia (Moscow-Svalbard) and Alaska (Arctic Village-Cordova) were involved in the comparison as well as the data of the IGS (International GNSS Service) network. The comparisons cover the time interval from 2003 to 2008, which includes both geomagnetically quiet and disturbed periods. We also demonstrate the possibilities of GPS/GLONASS TEC studies in connection with solar flares and artificial ionospheric heating.
