Rockwell Collins’s planned acquisition of airborne communications provider Arinc positions it to benefit both on the ground and in the air from the increasing “digitization” of airline communications. The future paradigm for ATC calls for replacing voice communications between pilots and controllers with digital data messaging, and Arinc’s ground infrastructure provides one of two major pipes for routing those messages.

South Korea has been subject to annual GPS jamming attacks by its North Korean neighbor since 2010. Over that period, jamming has extended over longer periods, with the longest being a continuous 16-day attack, employing various frequencies, techniques and signal strengths. As the jamming periods increased each year, they affected more and more GPS users. Last year, South Korean officials estimated that 1,016 aircraft lost GPS signals, as did 254 ships and a large number of cellphone towers.
With the continuing strains on the U.S. national budget and the possibility that the Administration’s sequestration program could last for several more years, Pentagon planners are said to be worrying that the costs of the future GPS III system could become out of reach, despite its major advances and the need to have modernized replacement satellites ready to be deployed as the orbital lives of current satellites end.
The FAA’s NextGen ATC modernization program faces long-term technical risks and still uncertain acceptance by airspace users. But after a decade in development, NextGen could be stalled by a nearer-term threat: substantially reduced funding from Congress. In June, the House appropriations committee released transportation funding legislation for Fiscal Year 2014 that would reduce the FAA’s capital funding account, which supports NextGen programs, to its lowest level since 2000.
The FAA claims the NextGen Air Transportation System initiative is progressing, according to its recently issued NextGen Implementation Plan report, which projects a reduction in delays of 41 percent by the end of the mid-term implementation period in 2020.
A request for tender (RFT) issued by Airservices Australia last month for the “oneSky Australia” program presents a “once-in-a-generation opportunity” to field a joint civil and military air traffic management system by 2020, according to the government-owned air navigation services provider.
Prime contractor Raytheon and the U.S. Federal Aviation Administration have finished installing the standard terminal automation replacement system (Stars) at the first of 11 large terminal radar approach control (Tracon) facilities in the U.S. Air traffic controllers at the Dallas/Fort Worth Tracon started “continuous operation” with Stars ahead of schedule in early May, Raytheon announced at the Paris Air Show last month.
If ever there was a Comeback Kid in avionics, it would have to be the FAA’s wide area augmentation system (Waas). Heralded by the agency in 1994 as the future Swiss Army knife of navigation, Waas was going to bring greater accuracy and enhanced reliability to the sometimes unpredictable GPS and, in so doing, promised a new era where satellites would replace not only the nation’s NDBs and VORs, but also the more than 600 Category 1 ILS installations in the National Airspace System at the time. Development would cost more than $300 million, and take about four years.
ITT Exelis has been awarded a $42 million contract from the Aireon venture to provide automatic dependent surveillance-broadcast (ADS-B) data processing and distribution for its satellite-based air traffic surveillance system. Aireon, a joint venture of Iridium Communications and Nav Canada, will provide aircraft position reports to subscribing air navigation service providers (ANSPs) using hosted ADS-B payloads on the Iridium Next constellation of satellites.
Air navigation service providers (ANSPs) have extended their ability to track aircraft flying on far northern Atlantic routes by installing automatic dependent surveillance-broadcast (ADS-B) stations in Greenland, the Faroe Islands and Iceland.
