Raspberry Pi: Dump1090 erzeugt auch JSON-Dateien die extern verwendet werden können – Wenzlaff.de

Dump1090 erzeugt auch JSON-Dateien, die periodisch aktualisiert werden und die auch extern verwendet werden können.

Dies sind ua. die folgenden Dateien:

aircraft.json
stats.json
receiver.json
history_0.json, history_1.json, …, history_119.json

Die genaue Dokumentation ist hier zu finden.

Über den Browser kann man auf diese Dateien z.B. so zugreifen, wenn ein externer Server verwendet wird:

http://(Raspberry Pi Adfresse)/dump1090/data/aircraft.json

im Dateisystem sind sie unter

/run/dump1090-mutability

zu finden.

Die aircraft.json liefert dann z.B. die folgenden Infos:
