Deal at U.N. meeting opens way for satellite tracking of jets
GENEVA -- A deal reached at a U.N. meeting on Wednesday opens the way for satellite tracking of airliners, a major breakthrough motivated by the mystery disappearance of a Malaysia Airlines jetliner last year.
The agreement allows nations to set aside radio frequencies so that airplanes can be tracked by satellite -- not just from the ground.
As CBS News' Amanda Schupak reported in March, just as you lose cell phone service when you go from the city into the woods, ground control can lose track of planes as they venture over vast regions of the globe that lack radar towers, including the southern Indian Ocean, where it is believed MH370 went down.
"If you look at the technology of air traffic control, it is safe to say that not a lot has changed since 1940. We are still using radar as the primary means of seeing aircraft," Cyriel Kronenburg, vice president of sales and marketing for air traffic surveillance company Aireon, told CBS News in March."It's ironic: As a passenger you often have WiFi onboard. Sometimes you actually have a better connection to the world than the pilot has."
Under current radar-based systems, the movement of planes is monitored by land-based systems, leaving around 70 percent of the world's surface uncovered, according to the International Telecommunications Union, the U.N. communications agency.
Modern planes that can send what are known as Automatic Dependent Surveillance-Broadcast, or ADS-B, signals to the ground are now on track to send signals to satellites too -- with implementation expected by 2017.
The accord to set aside the 1087.7-1092.3 MHz radio frequency for satellite tracking of planes came at the World Radiocommunication Conference, an international gathering organized every four years by the ITU. International civil aviation regulator ICAO has pushed for satellite tracking of aircraft, as long as current safety measures aren't jeopardized.
"The WRC's action today will enable better tracking and location of aircraft that otherwise could disappear from terrestrial tracking systems," said U.S. Ambassador Decker Anstrom, who is leading the U.S. delegation at the conference. "This is an excellent example of the ability of nations, working through the ITU process, to take action in improving peoples' lives."
The March 2014 disappearance of Malaysia Airlines flight 370 with 239 people on board exposed weaknesses in worldwide air navigation systems. Debris from the Boeing 777 was found in the Indian Ocean in July.
Officials praised the relatively quick work toward improving the ability to track planes. Shortly after the plane vanished, Malaysia's communication minister urged the ITU to help find new ways of transmitting flight data in real-time. In May 2014, ICAO called for quick action to allocate the spectrum so that satellites could help track planes in the future.
ITU Secretary-General Houlin Zhao said the agency has "responded in record time to the expectations of the global community on the major issue concerning global flight tracking."
