Ionosphere scintillation effects on navigation systems

open access: yesComptes Rendus. Physique, 2011
This article deals with the impact of ionospheric electron density inhomogeneities on the functionality of global navigation satellite systems emphasizing positioning errors. The scintillation characteristics of transmitted signals have been obtained using data gathered in measurement campaigns.

Weak-scattering theory for ionospheric scintillation [PDF]

open access: yes, 1997
The VHF scintillations recorded at Varanasi (geomag. lat.4147558N; geomag. long.4154 7E) are mostly weak scintillations. Using a thin phase screen model for ionospheric irregularities, under the approximation of weak-scattering theory, attempts have been

TEMPORAL VARIATIONS OF IONOSPHERIC SCINTILLATION INDEX ON COSMIC RADIOSOURCES OBSERVATIONS AT DECAMETRIC WAVE RANGE

open access: yesOdessa Astronomical Publications, 2017
The measurements of cosmic radiosources have scintillations on ionospheric irregularities at decametric waves. The analysis of temporal variations of the scintillation indexes was carried out on the base of observation data obtained on RT URAN-4 during ...

Radio propagation through solar and other extraterrestrial ionized media [PDF]

open access: yes
The present S- and X-band communications needs in deep space are addressed to illustrate the aspects which are affected by propagation through extraterrestrial plasmas. The magnitude, critical threshold, and frequency dependence of some eight propagation
