Evolution to modernized GNSS ionoshperic scintillation and TEC monitoring

Proceedings of the 2012 IEEE/ION Position, Location and Navigation Symposium, 2012
The ionosphere, if not modeled sufficiently well, is the largest contributor of error in single frequency GNSS receivers. Modeling ionospheric effects is a major concern for a number of GNSS applications. Ionospheric disturbances induce rapid fluctuations in the phase and the amplitude of received GNSS signals. These rapid fluctuations or scintillation

Investigation of ionospheric TEC over China based on GNSS data

Advances in Space Research, 2016
Abstract In this paper, the ionospheric total electron content (TEC) is derived from 250 Global Navigation Satellite Systems (GNSS) receivers over China. The GNSS TEC data are utilized to study the diurnal and day-to-day variability of ionosphere, ionospheric east–west differences and to construct regional ionospheric map. The GNSS–TEC curves clearly

GPStation-6 employment for GNSS TEC monitoring in SIRIUS project

2016 12th IEEE International Symposium on Electronics and Telecommunications (ISETC), 2016
HF communications have proved to be a quick and reliable solution for encrypted data transmissions in scenarios where other infrastructure is damaged or inexistent. However, the behavior of the ionosphere has to be predicted in order to model a suitable radio link and overcome the errors introduced during ionospheric propagation.

GNSS ionospheric scintillation and TEC monitoring using GPStation-6

2013 IEEE International Conference on Space Science and Communication (IconSpace), 2013
Ionospheric disturbances induce rapid fluctuations in the phase and the amplitude of received GNSS signals. Given the predictable impact of the Ionosphere on the GNSS signals, these signals provide an excellent tool for ionospheric monitoring on a global and continuous basis.

Local Monitoring of TEC Using GNSS Services over Romania

Romanian Journal of Physics
To increase the spatial resolution of available TEC maps, an existing technique has been modified to better fit the context of Romania and to minimize computational time. The resulting maps have a resolution of 55 km2 and require sparse data interpolation to fill in missing data.

Application of Probability and Statistics on GNSS Data to Analyze TEC Anomalies Generated by Earthquakes

Ionospheric disturbances are associated with the propagation of seismic waves generated by earthquakes. We analyze total electron content (TEC) fluctuations from Global Navigation Satellite Systems (GNSS) data. This study investigates the global earthquakes from December 2004 to March 2020 with magnitude (Mw) 4.0 to 9.1.
