Ein grauer Endnovembertag, eine geschlossene tiefhängende Wolkendecke, irgendwo da oben säuseln die Turbinen der Flugzeuge.
Urlaub wäre gut, aber die fliegen ohne mich. Doch wohin und wer fliegt da?
Flugzeuge senden ein Transpondersignal auf 1090MHz. Dieses Signal enthält Standort,Geschwindigkeit, Höhe, usw. und wird von einem DVB-T-Stick empfangen. Mit Dump1090 von MalcomRobb werden die Daten mit dem Raspberry Pi verarbeitet und im integrierten Webserver grafisch dargestellt. Das sieht dann so aus:

Vorraussetzungen:
– DVB-T-Stick inkl. Antenne
– fertig konfigurierter Raspberry Pi mit Netzwerk und Internetzugang
– cmake zum Kompilieren der SW-Komponenten RTL-SDR und Dump 1090 herunterladen und installieren:
