Predicted and measured slant ionospheric electron content
(Elsevier, 2005-12)
The total electron content (TEC) is used to indicate the ionisation of the ionosphere. TEC is a quantity with concern for telecommunications, detection systems, track, position, flight control and other systems that use ...
Slant total electron content for sirio-mortelliccio ray path
(Editrice Compositori, 2006-12)
The Total Electron Content (TEC) is used to indicate the ionisation of the ionosphere. TEC is a quantity that concern for predicting space weather effects on telecommunications, improving the accuracy of satellite navigation, ...
Tackling ionospheric scintillation threat to GNSS in Latin America
(Edp Sciences S A, 2011-01-01)
Scintillations are rapid fluctuations in the phase and amplitude of transionospheric radio signals which are caused by small-scale plasma density irregularities in the ionosphere. In the case of the Global Navigation ...
Signatures of equatorial plasma bubbles in VHF satellite scintillations and equatorial ionograms
(American Geophysical Union, 2013-02-22)
Since their discovery in the 1970s, equatorial plasma bubbles (EPBs) have been invoked to explain the propagation of VHF signals on trans‐equatorial circuits at night, and blamed for highly detrimental scintillation of VHF ...
Convective ionospheric storms: A review
(American Geophysical Union, 2011-06-22)
Equatorial spread F (ESF) was discovered almost a century ago using the first radio wave instrument designed to study the upper atmosphere: the ionosonde. The name came from the appearance of reflections from the normally ...
The role of altitudinal variation of scale height in determining the topside electron density profile over equatorial and low latitude sectors
(Elsevier, 2014-10-23)
Studies on the topside electron density profile variations have gained significant importance in the recent past in view of the trans-ionospheric communication and navigation applications particularly over the equatorial ...
Data ingestion into NeQuick 2
(American Geophysical Union, 2011-12)
NeQuick 2 is the latest version of the NeQuick ionosphere electron density model developed at the Aeronomy and Radiopropagation Laboratory of the Abdus Salam International Centre for Theoretical Physics (ICTP) ‐ Trieste, ...
Ionospheric Scintillation Fading Coefficients for the GPS L1, L2, and L5 Frequencies
(Amer Geophysical Union, 2018-09-01)
The terrestrial ionosphere over low-latitude regions presents the unique phenomena of the equatorial ionization anomaly (characterized by global maximum in plasma concentration) and plasma-depleted regions known as equatorial ...
A deep fading assessment of the modernized L2C and L5 signals for low-latitude regions
(2021-07-01)
When plasma instabilities arise in the post-sunset time, the so-called ionospheric plasma bubbles may develop, causing amplitude fades and phase oscillations, decreasing the availability and quality of transionospheric ...
