Plasmaspheric electron content derived from GPS TEC and digisonde ionograms

Advances in Space Research, 2004
The plasmaspheric electron content is extracted from the residuals of GPS-derived TEC measurements from estimates of the electron content obtained by a ground-based ionosonde at Athens (38°N, 23.5°E) over a 12-month time period.

Spectral analysis of planetary waves seen in ionospheric total electron content (TEC): First results using GPS differential TEC and stratospheric reanalyses

Journal of Atmospheric and Solar-Terrestrial Physics, 2007
The coupling of the neutral atmosphere and the ionosphere through planetary waves (zonal wavenumber 0-5) is investigated by spherical harmonic analyses of the ionospheric total electron content (TEC).

GPS Total Electron Content (TEC) estimation using single station measurements

2019 Sixth International Conference on Aerospace Science and Engineering (ICASE), 2019
Global Positioning System (GPS) operates in the microwave band, for which ionosphere is a dispersive medium and has a frequency-dependent effect on the signals. This effect can be used to gather vital information about the ionosphere itself in terms of the Vertical Total Electron Content (vTEC).

New receiver bias calculation for total electron content (TEC) in Bangkok, Thailand

2018 15th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON), 2018
Ionospheric delay is an important parameter which affects the positioning accuracy of Global Navigation Satellite System (GNSS). It can be analyzed from the total electron content (TEC) in the signal propagation path, computed from the code and carrier phase of at least dual-frequency GNSS signals.

Increases of equatorial total electron content (TEC) during magnetic storms

Journal of Atmospheric and Terrestrial Physics, 1976
Abstract This paper is a report on the analysis of equatorial electron content, TEC, during magnetic storms. Storms between 1969 and 1972 have been examined as part of an on-going study of TEC morphology during magnetically disturbed days. The published magnetic K p indices and TEC data from the Legon observatory have been employed.

Investigation of the annual solar eclipse by using Total Electron Content (TEC) measurements

2011 IEEE Symposium on Wireless Technology and Applications (ISWTA), 2011
This research investigates the ionosphere response to the annual solar eclipse on 26th January 2009 over Indonesia and Singapore. During solar eclipse, ionosphere will be affect due to the partial or complete obstruction of solar emission. It makes the number of electrons and ions decreases.

Total electron content (TEC) variability at Los Alamos, New Mexico: A comparative study: FORTE‐derived TEC analysis

Radio Science, 2005
Data collected from Fast On‐Orbit Recording of Transient Events (FORTE) satellite–received Los Alamos Portable Pulser (LAPP) signals during 1997–2002 are used to derive the total electron content (TEC) at Los Alamos, New Mexico. The LAPP‐derived TECs at Los Alamos are analyzed for diurnal, seasonal, interannual, and 27‐day solar cycle variations ...

Comparison of total electron content of IRNSS with IRI and GPS-TEC at equatorial latitude station

AIP Conference Proceedings, 2018
Total Electron Content (TEC) is the key element for observing the variation of the ionospheric signals. TEC is integrated electron density over the signal path from transmitter to receiver and measured in TEC units. The IRNSS SPS RX is used to track and provide accurate location information with 7satellite constellation system. The receiver consists of

Statistical analysis for the identification of precursory signatures of earthquake occurrence in Total Electron Content (TEC)

2020
<p>In the last few decades several parameters (chemical, physical, biological, etc.) have been proposed in association with the complex process of preparation of earthquakes. In particular, the variability of space weather has been proposed, since long time, as possible indicator of impending earthquakes.
