The FAA last month said it is expanding GPS WAAS coverage into Canada and Mexico by adding nine new wide-area augmentation system ground stations in places such as Goose Bay and San Jose del Cabo. The FAA has published about 900 LPV (localizer performance with vertical guidance) approaches in the U.S.
Reporting to Congress on the state of the FAA, DOT inspector general Kenneth Mead–the department’s program and fiscal watchdog– didn’t mince words in his assessment of the FAA’s equipment procurement and cost-accounting practices. The agency must, he stated flatly, “reexamine how it does business.”
The FAA awarded a $16.7 million contract–which could balloon to $340 million if options are exercised–to Honeywell International to build the first phase of the local-area augmentation system (LAAS) to deliver Category I precision landing systems at major U.S. airports.
After describing its GPS LAAS precision approach system contract as “imminent” for more than six months, the FAA in early May announced its award to Honeywell.
Concerned about attempts by adversaries to jam global positioning satellite system signals–as occurred with only limited success during the recent Iraq conflict–the U.S. Air Force is moving ahead with plans to field a new-generation constellation of satellites, called GPS III. After a months-long logjam, the Air Force next month will begin accepting requests for proposals to develop and deploy the satellites sometime between 2010 and 2013.
In 1997 the President’s Commission on Critical Infrastructure Protection, which was charged with examining threats to our national security, recommended an assessment be made of the vulnerability of the U.S. transportation infrastructure if it had to rely on GPS.
As part of its evaluation of loran as a potential backup to GPS, the FAA has contracted Rock-well Collins to build a combined GPS/loran variant of its standard multimode navigation and landing receiver. The unit’s primary function will be to provide GPS navigation, with automatic switchover to loran should GPS signals be lost or degraded, and automatic reversion to GPS when normal service resumes.
The woes experienced by builders of the wide-area augmentation system (WAAS) are nothing new to those who have followed the development of the satellite-navigation project over the last decade. In fact, it has become almost cliché to use woe and WAAS in the same sentence. So it’s not surprising to learn that a program one senator once referred to as a “$4 billion boondoggle” has lost luster over time.
Rockwell Collins has received the industry’s first TSO approval for a multi-mode receiver (MMR) with local-area augmentation system (LAAS) functionality, the avionics maker announced last month. The Collins GLU-925 MMR is the first to include LAAS and GPS landing system (GLS) capability in addition to ILS mode.
LAAS could end up being overtaken by a combination of the FAA’s WAAS and Europe’s GPS equivalent, Galileo. While official speakers at last month’s U.S.
