Is there a way to log / record ADSB data locally without streaming it to ADSBExchange? I will be at an airshow without wifi (cell hotspot not available), but I still want the tracking ability. Is there a way to do this so I can play back the tracks later?
You could come up with something to pull the JSON data off the feeder and log it.
You can take a look at my implementation of a portal at jprochazka/adsb-receiver
If you are looking to implement something on your own, you can use the following Python file as a reference in order to save data to an SQLite or MySQL database using dump1090 JSON as a data source. Mind you this is not tested against Readsb which the ADS-B Exchange image uses?
“modesmixer2” used to save aircraft in a SQB database file
and here is my command:
nohup ./modesmixer2 --inConnect localhost:30002 --inConnect localhost:30003 --inConnect localhost:30004 --inConnect localhost:30104 --inConnect localhost:30005 --web 1091 --location 53.xxx:-0.4321 --db BaseStation.sqb --frdb flightroute-iata.sqb &
exit
Copy could be found here:
You will probably need to install in order to run the “modesmixer2”
sudo apt install -y libssl1.1 libssl1.1-dev
EDIT:
The version “modesmixer2_aarch64_rpi4_Raspberry_Pi_OS_20210228.tgz” does not work …
