Open ADS-B data
a global network
born in Italy

About 3,200 receivers all over the world send us their ADS-B and Mode-S data directly. We compute the multilateration ourselves and filter nothing: military, PIA and LADD aircraft stay in.

What we collect

Global ADS-B Almost all of it comes from receivers that send us their data directly, in Europe, the Americas, Asia and Oceania. A small share comes from ADSBHub and OGN. picture · 0.5 s
Our own MLAT Our server works out the position of aircraft that don’t transmit full ADS-B, military included, from the times their signals reach the receivers. How many receivers, with the date → mlat-ng · port 30100
Mode-S BDS50/BDS60 True airspeed, magnetic heading and Mach number from Mode-S Comm-B replies. With them, the weather32 research, now complete, worked out the wind at altitude. BDS50 · BDS60

weather32 Meteorology Completed

Upper-troposphere wind measurement from aircraft in flight

We used airliners as sensors of the wind at altitude: we worked out the wind from Mode-S messages (BDS50/BDS60) and compared it with ERA5 reanalysis and IASI satellite profiles. The project is complete; method and results are on the research page.

Contribute

Join the network

With a Raspberry Pi, an RTL-SDR dongle and an antenna (about €55–110) you send your receiver’s data to the network. In return you get the API with Pro’s limits and features, free, and Lightcone, which shows the aircraft that passed near you and you did not receive, and how you compare with nearby receivers.
