The list of FAA GPS procedures using Waas, known by ICAO as space-based augmentation system (SBAS) procedures, continues to grow steadily. These include ILS-equivalent localizer precision with vertical guidance (LPV) approaches, providing centerline and glideslope guidance down to 200 feet at more than 800 Part 139 runways in the NAS, plus another 2,600 at various heights above 200 feet at other NAS Part 139 and non-Part 139 runways. At most of the non-Part 139 runways, of course, there’s no ILS, and probably never will be. SBAS is filling that need.
Rockwell Collins’s flight management system (FMS) and global navigation satellite system (GNSS) receiver successfully enabled the first demonstrations of advanced arrival and departure flight operations for the European Union’s airspace-enhancing project called FilGapp (“filling the gap” in GNSS advanced procedures and operations), the company announced today. FilGapp is intended to create new, more efficient methods of navigating airspace using satellite-based navigation and advanced FMS functions.
The first satellite-based precision approach system in the southern hemisphere enabled by Honeywell’s SmartPath entered service last week at Australia’s Sydney Airport. The technology, which is also known as a ground-based augmentation system (GBAS) in the U.S., offers precision guidance to within three feet of the runway centerline.
The media jumped on a May 13 report that Russian deputy prime minister Dmitry Rogozin had threatened that unless the U.S. allows Russia to install a ground station in the U.S. to monitor signals from its GPS-like Glonass satnav system, Russia would retaliate and “suspend the operation of U.S. GPS ground stations in Russia.”
The European Geostationary Navigation Overlay Service (EGNOS) provides clear benefits to the business aviation sector. With many business aircraft not specifically catered to by current air traffic management systems, more often than not they find themselves shut out of many key airports.
This is particularly true as Europe’s skies continue to become more and more crowded. As air traffic continues to grow, smaller airports must make themselves accessible at all times–something that cannot be done when relying solely on nonprecision approaches.
Resilience–broadly, the ability to readily recover from external disturbances–seems likely to become the next buzzword in aviation’s lexicon. It is gaining acceptance primarily to describe a future world air navigation system’s resistance to interruptions and outright signal loss, to provide pilots with essential, unfailing position, navigation and timing (PNT) data. Resilience came to the fore at a February conference on GNSS vulnerability, sponsored by the UK Institute of Navigation.
Airbus Helicopters and Esterline CMC (Booth No. 1414) have spent more than a decade collaborating on helicopter avionics, culminating in new certifications of avionics and airframes announced at Heli-Expo 2014. On display for the announcement were examples of Esterline’s CMA-9000 flight management system and CMA-5024 GPS landing system sensor in the Airbus EC175.
“Well over 1,000 CMC flight management systems are in service on Airbus helicopters,” said Greg Yeldon, president of Esterline CMC. “The navigation system on the EC175 is the latest example of this collaboration.”
A recent New York Times article described a Russian request to the State Department to approve U.S. locations for one or more terrestrial signal monitors for Russia’s Glonass satellite navigation system, similar to America’s GPS, suggesting the request could have worrisome consequences.
According to the article, “The CIA and other American spy agencies, as well as the Pentagon, suspect that the monitor stations would give the Russians a foothold on American territory that would sharpen the accuracy of Moscow’s satellite-steered weapons.”
Flight-testing at Toulouse, France, and Frankfurt, Germany, has proved that a reliable alternative to an ILS signal can be produced with a GNSS constellation and single-frequency input signal. Eurocontrol’s Sesar air traffic management research team worked with equipment manufacturers Thales, Indra-Navia, Honeywell and Thales Avionics using a ground-based augmentation system (GBAS). Further testing at both airports is expected to resume in the middle of next year.
When representatives from every world nation and every civil aviation organization gather at the triennial ICAO Assembly, topics on the agenda include current progress and issues as well as future challenges and potential solutions.
