Operators in the future will possibly be able to use X-rays from pulsating stars–or pulsars– light years away from earth to navigate with the same accuracy as GPS.

European nations apparently have resolved their objections over budgeting of Galileo, Europe’s $4.2 billion rival to GPS. Several EU nations had voiced concern about Galileo’s high cost, with some countries, most recently Spain, complaining they had been left out of commercial bidding negotiations. Under the final plan, Spain’s share increases from 9.5 percent to 10.25 percent. The cost of Galileo is being shared by 15 European countries.

The DOT Volpe Center’s September 10 report on the vulnerability of GPS to jamming and other interference, in addition to the events of the following day, have greatly heightened national concerns about the security of the satellite system and the degree of dependence that should be placed on it as the backbone of our future ATC system.

Last year was a challenging time for Galileo, Europe’s fledgling global navigation satellite system (GNSS). It started with the collapse of the private consortium established to build the system and culminated in European Union transport ministers making a “do or die” decision to allow the European Commission (EC) to manage the project in conjunction with the European Space Agency (ESA).

The FAA’s original plan to transition to sole-means GPS is no longer practical and some form of backup will be required for the foreseeable future, according to speakers at a recent Navigation Industry Day. This event was sponsored by the DOT, FAA and Civil Aviation Advanced Systems Development (CAASD), which is a component of the federally-funded MITRE research and development center and  a key FAA think-tank resource.

Speakers from Eurocontrol and the European Space Agency last month informed attendees at a meeting of the FAA’s Satellite Operational Implementation Team (SOIT) that their organizations would accept liability for system failures when the Galileo satnav system was used in critical applications requiring high-accuracy guidance, such as approach and landing operations.

Just when many thought loran was dead, it is coming back, albeit in a different guise. The President’s recently released FY2009 budget includes funding for the Coast Guard to continue operating the current loran network in readiness for its upgrade in 2009 to enhanced loran (eLoran).

OuterLink, a Lowell, Mass. company that specializes in mobile asset tracking, is at Heli-Expo 2008 promoting the latest version of its CommTrack satellite-based software suite and a new product, the CV2R cockpit voice and video recorder. Both are being featured at OuterLink’s booth (No. 2216).

Airborne video surveillance can give first responders and law enforcement a clear idea of what needs to be done on the ground in an emergency. But the challenge is making sure the information reaches the right people–that’s where Microwave Radio Communications’ (Booth No. 1313) experience can make a big difference, according to the Massachusetts company.

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.
