Automatic Dependent Surveillance-Broadcast (ADS-B) allows for aircraft identification, position, altitude, speed and other parameters to relay automatically to Air Traffic Controllers (ATCs) and stakeholders on the ground. Aireon’s space-based ADS-B system will allow controllers to receive an aircraft’s ADS-B signal in remote, oceanic and polar areas where aircraft are currently not visible. This capability will extend the same operational benefits that a controller has with radar without requiring new avionics, position reports or procedures.

Controllers will be able to significantly improve the way they separate oceanic and remote flights, improving safety and operational efficiency. Pilots will be able to request optimized flight altitudes on oceanic tracks and file more direct, user-preferred routing.  Real-time, 100 percent global surveillance also allows for more dynamic rerouting by ATCs as a result of weather events. This will enable pilots on oceanic crossings to reduce fuel burn and improve passenger comfort by climbing out of turbulent air.

A global contingency layer of ADS-B surveillance, available in every Flight Information Region (FIR) in the world, will reduce the operational impact and delays from major radar failures and create a smooth transition between oceanic and terrestrial flights that benefits all stakeholders, pilots included.

Increased Operational Efficiency

  • Improved ATC response to requests for deviation/speed/altitude change in procedural airspace
  • Increased access to user-preferred routes
  • Reduced training complexity through harmonization of ATC environment
  • More predictable and reliable operations

Enhanced Safety

  • Improved safety through early detection of gross navigation errors by ATC and by adding surveillance in currently unsurveilled airspace
  • Reduced impact from weather disruptions
