Tids Detection from Ship-Based GNSS Receiver. First Test on 2010 Maule Tsunami
The VARION (Variometric Approach for Real-Time Ionosphere Observation) algorithm has been successfully applied several times to TIDs (Travelling ionospheric disturbances) detection in a real-time scenario. VARION is, thus, able to estimate sTEC variations in real time and it can be applied on ship-based GNSS receiver since it is based on geometry free combination: the receiver motion does not affect the sTEC estimation process. This work is a feasibility study on the possibility to use data from ship-based GNSS receiver to detect
