Abstract

A sample of ionospheric scintillation activity measured in the African sector (Douala, magnetic latitude 5.36°N) is analysed, using measurements provided by a dual frequency GPS Ionospheric Scintillation and TEC monitor (GS V4004). The measurements consist of classical ionospheric scintillation indices evaluated at L1 and Total Electron Content (TEC) computed over 1 minute intervals on both L1 and L2. Measurements referring to quiet and disturbed conditions occurring between 4 November 2004 and 15 November 2004 were considered in this analysis. An overview of the scintillation activity in that event is presented (also in comparison with simultaneous measurements collected in the Brazilian sector). The importance of this type of analyses relies on the need to understand the potential threats to GNSS based applications.
