Data
Our data
The FlyItalyADSB network continuously collects radio signals from aircraft worldwide. These data feed the real-time map, meteorological research and air traffic analysis.
ADS-B — position and velocity
Automatic Dependent Surveillance–Broadcast. Every modern aircraft automatically broadcasts its position (CPR), barometric altitude, ground speed and track. Network receivers capture these signals at 1090 MHz and forward them to the central server. Updated every 200ms.
Mode-S EHS — avionics data
The Mode-S Enhanced Surveillance protocol transmits detailed avionics data: True Air Speed (BDS50), Magnetic Heading, IAS and Mach number (BDS60), temperature and direct wind (BDS44). These messages enable wind derivation using the technique W = V_ground − V_air.
MLAT — multilateration
Aircraft with Mode-A/C or basic Mode-S transponders do not broadcast GPS position. Through multilateration — measuring the time difference of arrival of the signal at at least 4 synchronized receivers — the MLAT server computes the triangulated position. FlyItalyADSB is the only MLAT provider active over Italy, including military coverage.
OGN — Open Glider Network
The Open Glider Network broadcasts positions of gliders, paragliders, drones and ultralight aircraft equipped with FLARM/FANET transponders. The flarm-ogn-to-sbs component converts these data into SBS format compatible with the map.
