A near real-time prototype service to monitor the effects of scintillations on GPS/GLONASS signals on a global scale

Résumé

Our aim is to analyze the effects of ionospheric scintillation by using the permanent worldwide GPS/GLONASS observations distributed by the International GPS Service (IGS). Three potential indicators are examined: the occurrence of losses of lock on the L2 frequency, the signal-to-noise ratio (when available) and the phase fluctuations. The prototype service provides global maps of scintillation intensity within two hours using a network of about 50 receivers at a 1 s repetition rate. It also provides daily updated global scintillation maps based on about 300 receivers with a 30 s repetition rate.
