Open ADS-B data
a global network
born in Italy
More than 3,200 receivers around the world send us ADS-B and Mode-S directly, with multilateration of our own — military aircraft included. Non-profit, unfiltered.
What we collect
| Global ADS-B | Feed from 3,200+ receivers that send to us first-hand, across Europe, the Americas, Asia and Oceania, plus adsb.lol and theairtraffic.com. | aircraft.json · 0.2s |
| Our own MLAT | Multilateration on aircraft without full ADS-B transponders, military included. Our own server, 1,800+ 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.
