demoThe system is installed in the University Campus (37° 57' 39,55'' N, 23° 42' 27,57'' E) on the meteorological mast at 11 meters height. It detects and tracks thunderstorms up to 500 km away in an updated rate of 30 minutes.It uses a direction-finding antenna to determine the direction of the VLF signal (7-15 kHz). The receiver looks at the signal strength to calculate an approximate distance for the lightning strike. There is additional processing done in software to reduce the effect of strike to strike magnitude variations. Once the receiver recognizes the direction and distance of the strike it plots it on the map. The system is planned to be expanded with 2 more detectors by the end of the year 2014.
