ADS-B receivers are electronic devices that listen for radio signals from ADS-B aircraft transponders and decodes them to determine
aircraft positions. FlightAware has created an open source software solution called PiAware to make aircraft data accessible to
everyone. PiAware uses low-power hardware like a Raspberry Pi, a Pro Stick (an inexpensive USB adapter),
and an antenna to receive signals from aircraft. Together, the software and hardware decipher and display the 1090MHz ADS-B data in
SkyAware, FlightAware’s web-based map interface that allows users to view aircraft positions on a local network. The receiver also
sends the data to FlightAware to provide free flight-tracking on flightaware.com.
