Blitzortung

The data is processed by various websites using geoinformatics methods and made available on the Internet as a map display.

The stations continuously digitise the low-frequency signals from the antennas in the range from 3000 to 30000 Hz with a sampling rate of over 500 kHz.

In this frequency range, the flashes generate particularly clear signal deflections, which lead to atmospheric interference in radio traffic and can generally also be perceived as crackling noises with a conventional AM radio in long and medium wave broadcasting.At the same time, a GPS signal is received and analysed.

Figuratively speaking, the server draws a hyperbola line around two of the receivers, which can be calculated from the propagation time of the signals around each station.

This method is generally referred to in surveying technology as multilateration, whereby the hyperlocation used here represents a special case of this, in which the points of equal time difference lie on hyperbola lines in the plane.

The findings, data and maps from Blitzortung.org repeatedly attract attention in the German and international media.
