Pulsations in total columnar electron content

Journal of Geophysical Research: Space Physics, 1981
Radio signals from the ATS 6 beacon received at Boulder reveal small‐amplitude, quasi‐sinusoidal fluctuations with periods in the range of 10 to 50 s. Visual comparison of these data (116 events for October 1974 to April 1975) shows a good correspondence with simultaneous geomagnetic pulsations at Boulder in two thirds of the cases for which Boulder ...

Towards Reliable Ionospheric Total Electron Content Nowcasting

2018 12th International Conference on Sensing Technology (ICST), 2018
Robust functioning of the global navigation satellite systems (GNSS) heavily depends upon nonlinear dynamics of ionospheric parameters. Nowcasting the dynamics of ionospheric parameters is challenging problem. Informative parameters selection for the accurate predictive models construction is considered as part of the novel approach based on the ...

Anomalous nighttime increases in total electron content

Planetary and Space Science, 1970
Abstract A study of anomalous nighttime increases in total electron content at Hawaii from September 1964 to September 1968 shows that the typical increase lasts from 2 to 4 hr, has a mean size of 6 × 1016electrons/m2, and peaks during 2100–2200 HST and 0100–0200 HST.

Total Electron Content Modelling and Mapping

2013
Although the main purpose of the Global Positioning System (GPS) was to provide accurate positional location at any point on or above the Earth’s surface at all times, for defence and civilian purposes, GPS also had a major impact on ionospheric science during the last decade of the twentieth century.

Total electron content measurements in ionospheric physics

Advances in Space Research, 2008
With the advent of modern global networks of dual-frequency Global Positioning System (GPS), total electron content (TEC) measurements along slant paths connecting GPS receivers and satellites at 22,000 km have become the largest data set available to ionospheric scientists.
