A satellite navigation backup study commissioned by the JPDO has given eLoran “the highest overall preference rating...particularly in the U.S.” Not yet publicly released, the 180-page document was prepared by ITT’s advanced engineering and sciences division and assessed seven candidates against a series of essential requirements.
On Sunday at EAA AirVenture Honeywell’s Bendix/King division unveiled two new products that are designed to win back market share from rival Garmin. The Bendix/King KSN 770 is a GPS WAAS navigator with integrated VHF navcom radios, joystick cursor controller and 5.7-inch-diagonal VGA display.
Occasionally, GPS satellites are spread across the sky in configurations that prevent a receiver from calculating a good position fix. When that happens, the unit’s receiver autonomous integrity monitor (RAIM) will generate an alert to the pilot to use an alternative navigation source.
A solar flare 10 times stronger than anything researchers had previously observed or predicted surprised scientists last December, not only because of its size and strength, but because of the effect it had on GPS receivers and other communications systems. Now scientists are looking at previous data and trying to understand how these flares affect satellite signals, in the hope that they can one day prevent further disruptions.
One of Eurocontrol’s senior navigation managers says the business aviation community should be acting now to prepare for the introduction of the EGNOS (European geostationary navigation overlay service) augmented satellite approach and landing system.
Lingering technical issues are forcing Garmin to delay plans for upgraded WAAS capability in the company's GNS 430/530 and GPS 400/500 panel-mount avionics, according to a spokesman. Explaining that the upgrades will require "a major software rewrite" in addition to minor hardware changes, the spokesman indicated that the capability is now not expected to be available before next year's third quarter.
The EBACE conference program will today focus on the Single European Sky program and what it will mean for business aircraft operators. The session, to be held from 3:30 p.m. to 4:30 p.m. in Hall 7 Salon 1 will be moderated by Bo Redeborn, Eurocontrol’s director of ATM (air traffic management) strategies. He will be joined by guest speakers Steve Zerkowitz of ATM consultancy BluSky Services and Serge Lebourg from Dassault Aviation.
Cessna last month was close to certifying a software update for the Citation Mustang’s G1000 avionics system after avionics maker Garmin in February uncovered a programming glitch. The problem is causing course deviation errors and a loss of some navigation cues on the map display when the pilot attempts to load a new arrival or departure procedure without deleting a previously loaded procedure.
AIN was informed that the Departments of Transportation and Homeland Security were expected to announce jointly late last month that the U.S. loran transmitter network will continue in operation. How long the system will remain in service is uncertain, but observers believe it could be 10 years, and possibly longer. An independent panel of experts– chaired by “father of GPS” Dr.
Mercury Computer Systems introduced two new class II-qualified electronic flight bag (EFB) systems targeting operators of larger aircraft. Mercury’s original VistaNav EFB class-I CIS-1000 is a tablet PC offering a 2-D or 3-D synthetic view of the outside world, including highway-in-the-sky approaches. The tablet receives wireless signals from a separate inertial navigation unit housing a WAAS GPS receiver and solid-state gyros.
