Near Real-Time Ionospheric Scintillation Maps

Welcome to the Transionospheric Radio Link - Near-real-time Ionospheric Scintillation Maps service

Overview

Trans-ionospheric radio signals of global navigation satellite systems (GNSS) like GPS, GLONASS, and GALILEO may suffer from rapid and intensive fluctuations of their amplitude and phase caused by small-scale irregularities of the ionospheric plasma. This phenomenon, which is called radio scintillation, can strongly disturb or disrupt the signal transmission. For technical applications it is useful to derive and to provide the well accepted S4 and σΦ indices describing the amplitude/ intensity and the phase fluctuation of a received signal, respectively. For that purpose GNSS high-rate receivers in Europe provide necessary receiver-satellite-link specific amplitude and phase information.

This service provides near-real-time local scintillation data as well as regional and global maps. Additionally, solar and geomagnetic indices are provided, applicable for forecast or background models.
