<abstract>
The Global Ionospheric Flare Detection System (GIFDS) of the DLR consists of
a ground-based network of VLF receivers (Perseus SDR - Software Defined Radio),
which provides signal strength and phase measurements at multiple frequency
channels from 10 to 60 kHz. One of the main objectives of GIFDS is the immediate
and continuous detection of solar flares as a result of their impact on the
bottomside ionosphere and consequently their sudden effects on VLF signals. As
such events can only be detected during daytime, DLR is installing a uniform set
of receivers at selected locations around the world. Measurements carried out at
the dayside sector will be provided 24/7 in the near future.
