Press release: Radio spectrum allocated for global flight tracking

ITU World Radiocommunication Conference enables Earth-to-space reception of ADS-B transmissions

Geneva, 11 November 2015 – Agreement has been reached at the World Radiocommunication Conference in Geneva on the allocation of radiofrequency spectrum for global flight tracking in civil aviation.

The frequency band 1087.7-1092.3 MHz has been allocated to the aeronautical mobile-satellite service (Earth-to-space) for reception by space stations of Automatic Dependent Surveillance-Broadcast (ADS-B) emissions from aircraft transmitters.

The frequency band 1087.7-1092.3 MHz is currently being utilized for the transmission of ADS-B signals from aircraft to terrestrial stations within line-of-sight. The World Radiocommunication Conference (WRC-15) has now allocated this frequency band in the Earth-to-space direction to enable transmissions from aircraft to satellites. This extends ADS-B signals beyond line-of-sight to facilitate reporting the position of aircraft equipped with ADS-B anywhere in the world, including oceanic, polar and other remote areas…
