That would probably be the ADS-B system Amuro Ray referred to back on page 10. The plane gets its own position from GPS receivers, and relays that back, typically via VHF radio... basically like someone getting on the mic and saying, "Our coordinates are blah blah blah blah", but automated.
If the radio systems go down, though, then the plane has to way to transmit that information.
