Open ADS-B data
a global network
born in Italy
About 3,200 receivers all over the world send us ADS-B and Mode-S directly, with multilateration of our own — military aircraft included. Open, unfiltered.
What we collect
| Global ADS-B | Feed from about 3,200 receivers that send to us first-hand, across Europe, the Americas, Asia and Oceania, plus a small share from ADSBHub and OGN. | aircraft.json · 2s |
| Our own MLAT | Multilateration on aircraft without full ADS-B transponders, military included. Our own server, about 3,200 synchronised receivers — exact count and date → | mlat-server · port 30100 |
| Mode-S BDS50/BDS60 | True Air Speed, magnetic heading and Mach number via Mode-S Comm-B. Used to reconstruct upper-troposphere wind profiles. | BDS50 · BDS60 |
Ongoing research
From airspace to science
Upper-troposphere wind measurement from aircraft in flight
Commercial aircraft are distributed meteorological sensors at altitude. By extracting wind components from Mode-S messages (BDS50/BDS60) and comparing them against ERA5 reanalysis and IASI satellite profiles, we are validating the quality of avionics data as an independent meteorological source.

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