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 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.
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.
Honeywell has received FAA supplemental type certificate approval for installation of its Sky Connect Tracker III in S-76, AW139 and AS350 helicopters. Sky Connect Tracker III uses the Iridium satellite network to provide all-in-one voice, text and tracking services. Honeywell said its dual-redundant servers currently handle more than 5 million tracking, text and telemetry messages each month.
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.”
India’s GPS-Aided Geo Augmented Navigation (Gagan) system, jointly developed by Airports Authority of India (AAI), the Indian Space Research Organization and Raytheon, has been awarded certification for in Required Navigation Performance (RNP) 0.1 operations. Achieved with the help of quasi-U.S. government non-profit MITRE Corporation, the certification makes it the world’s fourth SBAS system certified for operational use.
Esterline CMC (Booth T87) is celebrating a couple of milestone contract awards here at the Singapore Airshow this week, as well as showcasing its main avionics products–including its popular Cockpit 9000 CNS/ATM update solution for legacy Lockheed C-130 Hercules aircraft. This is aimed at extending the service life of 20-40 year-old aircraft by up to 30 years, future-proofing them against advances in ATC technology.
As concern over the jamming of GPS signals grows, Elbit Systems (Booth N65) announced that it had sold its iSNS immunity system to an unspecified Asia Pacific country for installation on maritime surveillance aircraft. The Israeli company claims that the system provides full jamming immunity for multiple satellite channels and handles multiple interfering signals and/or jammers operating on concurrent frequencies. ISNS is very flexible and can work with all types of GPS, without prior knowledge of satellite locations, Elbit says.
