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.
Global Positioning System
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.
Pilots all over the world are probably sick of hearing that “ADS-B is coming,” but the fact is that some countries already require ADS-B capability, and other countries’ deadlines are rapidly approaching. ADS-B equipage needs to remain prominent in pilots’ consciousness because avionics shops need time to certify ADS-B out installations and time to complete the installations. A rough estimate by Cessna’s product support organization, just for the U.S.
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.
The U.S. Navy recently completed engineering and manufacturing (EMD) development of the ship-based component of the Joint Precision Approach and Landing System (Jpals). The EMD phase of Jpals Increment 1A for ship systems included auto landings by F/A-18C Hornets to the deck of the aircraft carrier USS Theodore Roosevelt. The Increment 1B phase calls for integrating the system on aircraft.
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.”
The FAA’s refusal to acknowledge reality rears its ugly head in Advisory Circular 120-76B, Guidelines for the Certification, Airworthiness, and Operational Use of Portable Electronic Flight Bags.
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.
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.
