Abstract

The aim of this article is to introduce a technology of investigation of the ionosphere based on the reception of a numerical broadcasting fixed link at 6.085 MHz using the DRM (Digital Radio Mondiale) modulation properties as an opportunistic ionospheric sounder. The analysis used tools are Dream and SpectrumLab software. Observations are accomplished at the same time in narrow band (2Hz) and in wide band (10 kHz). They are presented by dopplergram. Different ionospheric characteristic events are observed in narrow band (typical figures at the opening and at the closing of the link, scattering, absorption, gravity waves) and in large band (selective fading, scattering, absorption). Different typical examples are presented.
