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.

Aspen Avionics is celebrating its 10th anniversary at AirVenture 2014 and installation of the Aspen retrofit glass-panel EFD 1000 in more than 9,000 aircraft. First introduced in 2006 and with deliveries beginning in 2008, the EFD 1000 offers a simple upgrade path by fitting into standard instrument panel holes while adding modern capabilities to older aircraft. “You literally have in your cockpit today more capable avionics than in a 737,” said Aspen president and CEO John Uczekaj. “It’s been quite a remarkable journey in a short time.”

Connext

On the eve of EAA AirVenture 2014, Garmin unveiled a major software upgrade to its GTN series navigators, new devices for the Connext wireless cockpit communications system, a new WireAware wire-strike avoidance feature for obstacle databases and new seven-inch touchscreen displays in the G3X experimental avionics line. All are being demonstrated at the Garmin exhibit (Booth 4089, Hangar D).

The first two satellites for the Galileo system will be launched next month from Kourou, French Guiana.

This summer will see significant progress in the world’s first civilian-owned and -operated satellite navigation system as Europe prepares to dispatch the first two full-capability Galileo satellites for lift-off.

Payload preparation for Arianespace’s Soyuz Flight VS09 started in earnest in early May with the arrival in French Guiana of the first two Galileo full operational capability (FOC) satellites.

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.”

Small and medium-size airports in Europe often lack the infrastructure necessary to enable complex approaches, limiting the utility of the airport. EGNOS, and the highly accurate position data it provides, makes these airports more accessible for business aviation operations without the cost of complicated ground structure.

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.

The FAA on March 28 published a revised version of AC No: 20-138D that clarifies and adds new guidance material to the airworthiness approval process for a variety of GPS systems, including augmented GPS, and Rnav equipment for RNP operations and baro-Vnav equipment.
