This map shows all active ADS-B sites as well as the average high-altitude coverage (200mi / 320km).
Many variables (e.g. antenna/receiver quality, installation factors, obstructions, etc.) impact the actual coverage. This map includes both FlightAware facilities as well as data submitted by feeder sites. For security and privacy reasons, the depicted positions of the sites are not exact.
