Officials for Jeppesen report that the company has identified and corrected many of the irregularities in its NavData boundary data, but at press time about 350 of the more than 20,000 boundaries included in the latest update of the database, effective March 20, had not yet been fixed. The error arose from problems with a software upgrade when data was pulled from a database containing airspace boundaries worldwide for the March update.

The FAA awarded a contract to Lockheed Martin last month that will add a third leased geostationary satellite to the two existing satellites used for the wide-area augmentation system (WAAS). Acquisition of a third satellite follows a recommendation from an independent review board study that concluded it was too risky to depend on only two satellites for the availability of the WAAS signal.

The combination of GPS position, digital communications networks and the Internet has made possible–and affordable–a variety of products and services for continuous real-time tracking of aircraft fleets by dispatchers on the ground. Nowhere has such capability been more eagerly accepted than in the realm of helicopter flight operations, many of which are now using data-link services to keep close tabs on their aircraft at all times.

While EGNOS, SBAS, GBAS and Galileo may be unfamiliar to most North American aviators, they are key elements in Europe’s determined move to a satellite air traffic control environment. Addressing the FAA’s satellite operations implementation team meeting in December, Eurocontrol officials reported on progress toward their vision of

The FAA has certified an IFR WAAS receiver developed by UPS Aviation Technologies, the key ingredient in a forthcoming line of satellite navigation equipment from the Salem, Ore. avionics maker.

While the GPS wide-area augmentation system (WAAS) is likely to be commissioned for public use in July, the local-area augmentation system (LAAS) has fallen back by 12 months, with commissioning of the first installation now forecast in late 2005. This setback for LAAS was revealed to attendees at a December briefing given by FAA’s Satellite Operational Implementation Team (SOIT).

Garmin announced the availability of fault-detection and exclusion (FDE) software for its GNS 430/530 GPS/navcom radios. According to a spokesman, FDE uses a mathematical algorithm to monitor the accuracy and reliability of GPS signals. Designed to detect erroneous GPS data, the software automatically excludes that data from the active navigation solution.

Last year in Toulouse, France, Eurocopter completed two series of tests that demonstrated the feasibility of satellite-navigation precision approaches for helicopters. Europe, which lags behind the U.S. in creating satnav nonprecision approaches for helicopters, has almost completed some research toward addressing that imbalance.

Is ILS, aviation’s trusted friend for the past half century, now seeing its last days? Probably not. Some observers believe it has many years of life ahead of it, yet newer technologies are slowly entering the scene, in such diverse settings as Norway’s fjords, Heathrow’s jam-packed runways, the icy wastes of Antarctica and at several major U.S. hubs.
