![]() ![]() Iridium backs an ADS-B solution Inmarsat has appeared to resist it, saying Inmarsat’s current technology, already on thousands of aircraft, is enough to do the job. Mobile satellite services providers Inmarsat of London and Iridium Communications of McLean, Virginia, have been sparring over this point for the past couple of years. The International Civil Aviation Organization (ICAO) of Montreal has asked that WRC-15 extend an existing regulatory regime related to the 1090-megahertz spectrum, used for a terrestrially based aircraft navigation service called Automatic Dependent Surveillance-Broadcast, or ADS-B, to satellites. ITU governments earlier this year made clear that they wanted action at WRC-15 to make it impossible for a large commercial jetliner to disappear from view, as was the case with Malaysian Airlines Flight 370 in March 2014. “We are fully ready for the ITU to welcome them,” he said of the proposed Internet constellations. Rancy, who had been in the thick of those battles as part of France’s National Frequencies Agency, said no more new regulatory ground need be plowed. Rancy said WRC conferences of the ITU’s 193 member nations took up nongeostationary-orbit telecommunications satellites in 1995, 1997, 20. “We’ve been ready for 20 years,” Rancy said when asked if ITU was prepared to deal with the half-dozen proposed constellations - in C-, Ku- and Ka-band - that have placed initial spectrum reservation applications at the United Nations agency.

In a press briefing, Francois Rancy, director of the ITU’s Radiocommunication Bureau, said ITU members wrestled for years with the spectrum-sharing issues associated with hundreds - now, potentially thousands - of satellites in low Earth orbit using the same frequencies as ground-based networks and geostationary satellites in higher orbit. 2-27, the International Telecommunication Union (ITU) said that, as of now, there is no need for WRC-15 to address the recent flurry of regulatory submissions on mega-constellations of satellites providing global Internet service. PARIS - International radio-frequency regulators on April 2 agreed to address satellite-based global commercial aircraft tracking when they meet in November to allocate spectrum at a conference that will also decide whether frequencies currently reserved for satellite services will be opened to terrestrial broadband wireless networks.Įnding an 11-day meeting in Geneva to prepare for the month-long World Radiocommunication Conference (WRC-15) set for Nov.
