Tracking Aircraft with Redis + Software Defined Radio
summary
Connects an RTL-SDR dongle and an aircraft antenna to dump and parse ADS‑B at 1.090 GHz with dump1090, a node sps1 parser, and Redis Streams (XADD/XREAD) via Re:Stack. Claims a home setup on a 25 ft mast receives 360,000 messages an hour; current single consumer architecture processes an aircraft in ~30 ms so it needs horizontal scaling. The demo assembles a Dockerized ingestion + websocket UI, and it successfully picks up live aircraft (one required opening the door for better reception).
