You can now build and run your own ADS-B ground station that can be installed anywhere and receive real-time data directly from airplanes on your computer. Your ground station can run FlightAware's PiAware software to track flights within 100-300 miles (line of sight, range depending on antenna installation) and will automatically feed data to FlightAware. You can track flights directly off your PiAware device or via FlightAware.com.
