Tracking Aircraft with Redis & Software-Defined Radio
summary
Shows how cheap hardware and real tools capture live aircraft data: a $30–50 RTL‑SDR dongle plus SDR Angel or rtl_433 feeds dump1090 at 1090 MHz, parsed by a Node.js ingester and appended into Redis Streams on Redis Stack. A consumer updates per‑aircraft hashes, exposes a search API and websocket feed, and a frontend maps positions. Demo picks up a nearby helicopter and AIS/vehicle beacons; live reception is spotty in concrete venues so recorded ADS‑B traces are injected to prove the UI and pipeline.
