Approaches to studying the multiscale ionospheric structure using nanosatellites

Past, Present and Future of Active Radio Frequency Experiments in Space

“…The Spire Global Inc. has launched constellations of CubeSats in low and high inclination orbits with GPS radio occultation payloads and plans to operate dozens of CubeSats for global monitoring of ionospheric electron density and lower atmosphere applications. Several other examples of using CubeSats to study local ionospheric inhomogeneities over the heating facilities are given by Chernyshov et al [2016].…”

Ionospheric Plasma Fluctuations Induced by the NWC Very Low Frequency Signal Transmitter

“…Conversely, radar receivers can record the effect of pre-existing structuring of ionospheric plasma on radio signals, by examining the rapid scintillations in radio signal phase and amplitude caused by changes in local plasma refractive index (Yeh & Liu, 1982;Kintner P. M. et al, 2007;Jin et al, 2017). Lastly, the effects by radio signal transmission of heating or accelerating plasma can readily be scrutinized in-situ, using sounding rockets or satellites (T. Leyser, 2001;Chernyshov et al, 2016;Streltsov et al, 2018).…”

In Situ Observations of Ionospheric Heating Effects: First Results from a Joint SURA and NorSat‐1 Experiment

“…These ionospheric disturbances are relatively short lived (with lifetimes of the order of seconds or to tens of minutes) and do not cause irreversible changes in the plasma. The current stage in the development of active experiments includes the use of satellites for sensing plasma disturbances in situ (Chernyshov et al, 2016(Chernyshov et al, , 2020Streltsov et al, 2018). However, these data can only be obtained if the satellite crosses an HF-perturbed magnetic flux tube, which rests on a region with highly developed turbulence generated near pump wave reflected altitude; in other words, "the satellite has to be in the right place at the right time.…”
