Data Content

Spire has harnessed terrestrial and satellite ADS-B tracking data from the positional Tracking Stream API to produce a unique FIR Overflight Report. FIR (flight information region) overflight data offers crucial insights into aircraft as they traverse designated airspaces operated by ATS (air traffic services).

This new and independent sibling of the Flight Report uses a sophisticated in-house algorithm to identify all description of overflights across the globe's FIRs.
