FlightAware is excited to announce that in addition to ADS-B flight tracking, PiAware (v2.1 and above) now supports live multilateration (MLAT) flight tracking of non-ADS-B aircraft. By triangulating the Mode S signal from non-ADS-B aircraft, PiAware can now track twice as many aircraft around the world!
Aircraft being tracked with MLAT will be in blue on your local web interface. If you’re not seeing any blue aircraft, make sure you have the most accurate location and elevation set here on your stats page and also read below about improving coverage. MLAT flights and stats will soon be available on FlightAware.com as well.
For MLAT to work, an aircraft needs to be within line of sight of four PiAware ground stations. To improve MLAT coverage in your area, you need to recruit friends to setup PiAware so your receivers can work together to track flights! Please post about this announcement and share the setup link flightaware.com/adsb/piaware/build via:
Emails to friends and family in your area
Please spread the word and help expand MLAT coverage using PiAware! The more PiAware receivers near you, the more availability of MLAT data.
Thanks for using FlightAware and PiAware!
