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.
Airport and aircraft sales information provider Globalair.com has added GPS locating to its FBO Fuel Prices Apple iOS app. The new GPS functionality allows pilots to use the app in the air to view fuel prices for nearby airports and easily compare prices in a particular area. The FBO Fuel Prices app costs $3.99 (one-time fee) and is continually updated with fuel prices from the more than 3,000 FBOs in the Globalair.com Airport Resource database. Most fuel prices are updated frequently and none is more than 30 days old.
NobileSoft, a software company created by a helicopter pilot, has joined forces with independent research company Sintef to bring to market a new GPS-based powerline warning system for low-flying aircraft. Collisions often occur when aircraft fly at low levels on power- or pipeline patrols.
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.”
GPS Source, a manufacturer of indoor GPS receivers, released its GLI-Metro-G system, which provides a variety of GPS signal types and control over effective radiated power (ERP) levels. GLI-Metro-G can receive GPS L1/L2 and Glonass L1/L2 signals, and users can select both GPS and Glonass or each type individually. An antenna must be mounted on the outside of the building to pass the signals through to the receiver. GLI-Metro-G will also accept Galileo signals when that system becomes operative, as well as those from other future GPS-type systems.
According to NBAA, the FAA will publish a notice to airmen on December 12 detailing plans for the rollout of Phase 2 of the North Atlantic datalink mandate. Implementation will begin with Phase 2a on Feb. 5, 2015, at which time flights within the North Atlantic Tracks (NAT) between FL350 and FL390 must be equipped with Fans 1/A controller-pilot datalink communications and ADS-C systems. The program expands to these altitudes in the entire ICAO NAT region on Dec.
In aviation, we tend to consider our use of GPS one of the more important applications of the technology, especially when compared to, say, drivers on downtown shopping expeditions. And, of course, it is.
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.
