About the Network

ADSB IQ aggregates ADS-B data from volunteer feeders running RTL-SDR receivers. Each feeder's data is combined to create a comprehensive real-time picture of aircraft positions. The server runs readsb in network-only mode, with MLAT processing for aircraft without GPS-based ADS-B.
