tThe World Radiocommunication Conference (WRC-15), currently half-way through its month-long residency in Geneva, has agreed to radio frequency spectrum for global flight tracking in civil aviation.
tEncouraged by a number of stakeholders, including the International Civil Aviation Organization (ICAO), WRC-15 has allocated the 1087.7-1092.3MHz band for the purpose of aeronautical mobile-satellite (AMS) service (Earth-to-space) for reception by space stations of Automatic Dependent Surveillance-Broadcast (ADS-B) emissions from aircraft transmitters.ttThis band is currently used for the transmission of ADS-B signals from aircraft to terrestrial stations within line-of-sight. The decision of the WRC extends this reach 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.tt“In reaching this agreement at WRC-15, ITU has responded in record time to the expectations of the global community on the major issue concerning global flight tracking,” said ITU secretary-general Houlin Zhao. “ITU will continue to make every effort to improve flight tracking for civil aviation.”tt“The allocation of frequencies for reception of ADS-B signals from aircraft by space stations will enable real-time tracking of aircraft anywhere in the world,” said François Rancy, director of the ITU Radiocommunication Bureau. “We will continue to work with ICAO and other international organizations to enhance safety in the skies.”ttIn statement, the WRC said it recognised that as the standards and recommended practices (SARP) for systems enabling position determination and tracking of aircraft are developed by the International Civil Aviation Organization (ICAO), the performance criteria for satellite reception of ADS-B signals will also need to be addressed by ICAO.t
