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.

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 ...

The capability of Artificial Neural Networks as a Model for Predicting Total Electron Content (TEC): A Review

TANZANIA JOURNAL OF SCIENCE AND TECHNOLOGY, 2023
The results of investigations from a complete analysis of ANN application on Total Electron Content (TEC) prediction are presented in this paper. TEC is important in defining the ionosphere and has many everyday applications, for example, satellite navigation, time delay and range error corrections for single frequency Global Positioning System (GPS ...

A statistical comparison of vertical Total Electron Content (TEC) from three ionospheric models

2008
[1] Total electron content (TEC) exhibits significant variations in both space and time depending upon latitude, longitude, solar cycle, UTC, and season; these variations can have potentially negative effects on communication and navigation systems. Recently, three models have provided accurate results in reconstructing and/or calculating real-time (or

Ionospheric Correction for MARSIS on Mars Express and Total Electron Content (TEC) Estimation

2007
MARSIS surface echoes need a ionospheric correction because the two-way travel through the ionosphere defocuses the signal. This process provides also a powerful tool to study the ionosphere and more particularly the Total Electron Content (TEC).
