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:
