INDONESIAN TSUNAMI EARLY WARNING SYSTEM AUGMENTATION USING GNSS-TEC [PDF]

Science of Tsunami Hazards, 2020
The Indonesian tsunami early warning system (INATEWS) has been developed and operated after the tsunami struck Aceh in December 2004. The INATEWS is based on a relationship model of earthquake parameters and tsunami potential.

Geometric quality term for station-based total electron content estimation

Annals of Geophysics, 2016
Global ionospheric maps (GIMs) are still commonly used to represent total electron content (TEC). However, a large number of permanent GPS receivers provide significant data for monitoring ionosphere.

Investigating short-term earthquake precursors detection through monitoring of total electron content variation in ionosphere

Frontiers in Astronomy and Space Sciences, 2023
The effectiveness and accuracy of earthquake precursors are measured by the ability of the precursors to predict the time, epicentral distance, and magnitude of the earthquake for short-term earthquake prediction.

MITIGATOR: GNSS-Based System for Remote Sensing of Ionospheric Absolute Total Electron Content

Universe, 2022
Monitoring the Earth’s ionosphere is an important, fundamental and applied problem. Global Navigation Satellite Systems (GNSS) provide a way of measuring the ionospheric total electron content (TEC), but real-time single-station absolute TEC measurements
