The Global Ionospheric Flare Detection System (GIFDS), operated by the German Aerospace Center (DLR), consists of a ground-based network of Perseus SDR (Software Defined Radio) receivers which provide concurrent measurements of VLF signal strength and phase at multiple frequency channels ranging from 10 kHz to 100 kHz. One of the main objectives of GIFDS is the immediate and continuous detection of solar flares affecting the bottomside ionosphere and consequently inducing sudden interferences of VLF signals. For this purpose, a network of four operational receivers is installed (yellow circles). Two further receiving stations are currently in progress (orange circles).
