ITU assigns new global flight tracking spectrum

Global Flight Tracking

[blockquote right=”pull-left”]
[/blockquote]The disappearance and tragic loss of Malaysian Airlines Flight MH370 in March 2014 with 239 people on board, spurred worldwide discussions on global flight tracking and the need for coordinated action by the Intern national Telecommunication Union (ITU) and other relevant organizations. Today, an agreement has been reached at the 2015 World Radiocommunication Conference (WRC-15) in Geneva on the allocation of radio frequency spectrum for global flight tracking in civil aviation.

ITU has chosen to utilize the frequency band 1087.7-1092.3 MHz that is currently utilized for Automatic Dependent Surveillance-Broadcast (ADS-B) signals from aircraft to terrestrial stations within line-of-sight now will be utilized by the aeronautical mobile-satellite service (Earth-to-space) for reception by space stations of ADS-B emissions from aircraft transmitters.  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. The WRC-15’s allocation of this frequency band in the Earth-to-space direction will enable transmissions from aircraft to satellites.

In its special meeting on global flight tracking, which took place in Montréal, May 12-13, 2014, ICAO encouraged ITU to take urgent action to provide the necessary spectrum allocations for satellites to support emerging aviation needs. In October 2014, the ITU Plenipotentiary Conference meeting in Busan, Republic of Korea, instructed WRC-15 to consider global flight tracking in its agenda. ITU Secretary-General Houlin Zhao said ;

“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 will continue to make every effort to improve flight tracking for civil aviation.”

Commenting on the new assigned spectrum François Rancy, Director of the ITU Radiocommunication Bureau said;

“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“We will continue to work with ICAO and other international organisations to enhance safety in the skies.”
