ADSB & UAT Feeder

Project preview

I use a Raspberry Pi 5 with two RTLSDR dongles filtered to the ADSB (1090MHz) and UAT (978MHz) bands. These are attached to tuned antennas attached to a PVC pipe antenna tower.

Another Raspberry Pi on the network provides GPS disciplined NTP and location services that help the feeder syncronize with other recievers to provide multilateration positioning.

I used to manage my own image of Raspbian with a custom installation of dump-1090 but I have switched to using sdr-enthusiasts/docker-adsb-ultrafeeder which allows docker-compose to manage the feeder and simplifies upgrades dramatically. I am considering turning it into a Helm chart and deploying it via K3s, but I haven’t done it quite yet.
