The FAA has issued a technical standard order and blanket installation approval covering 850 aircraft models for the CNX80 all-in-one GPS navcom from Salem, Ore.-based UPS Aviation Technologies. The company, a subsidiary of parcel shipping giant UPS, lays claim to being one of the first avionics manufacturers to gain FAA certification for a GPS receiver approved for WAAS instrument approaches.

At recent public hearings in Washington, D.C., and Albuquerque, N.M., DOD and DOT representatives reviewed the departments’ policies toward the provision of radionavigation services to the U.S. civil user community between now and 2020. The hearings were held to solicit user comments on those policies before publication of this year’s federal radionavigation plan (FRP), which will be available by year-end.

The FAA flipped the switch on its wide-area augmentation system (WAAS) at 12:01 a.m. on July 10, potentially opening up thousands of runways at 5,400 public-use airports for near-precision approaches in both lateral and vertical guidance modes.

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.

Honeywell has completed a series of GPS-guided autoland approaches to each of the four runways at Moses Lake Airfield in central Washington using a single Honeywell/Pelorus local-area augmentation system (LAAS) ground station. The successful trials, conducted over a 45-day period that ended in January, come just as
the FAA is preparing to award a major contract for the supply of 60 Cat I LAAS ground stations through 2007.

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).

Before GPS, approach classifications were cut and dried–they were either precision (ILS) or nonprecision approaches. But as pilots move into the future, they will need, before considering an approach into an “obstacle-rich environment,” to first navigate through an acronym-rich environment of new terminology to decide how to reach the threshold.

Honeywell’s aerospace electronic systems group is beginning the year by unveiling new technology that holds the promise of doing to conventional navcom radios what the personal computer did to electric typewriters.

Rockwell Collins announced the successful completion of microwave landing system (MLS) Category IIIb approach tests in the U.S. and Europe, with the aim of obtaining TSO approval for its multi-mode receiver (MMR) in the first quarter of this year.
