- W577104397 abstract "NAV Canada and the Federal Aviation Administration (FAA) announced in September of 2004 that NAV Canada will host and maintain four ground monitoring stations, which will enable the airspace to have access to Wide Area Augmentation System (WAAS) signals, improved Global Positioning System (GPS) navigational devices and improved runway approach systems. WAAS offers positioning accuracy to within about two meters throughout a flight, its most publicized capability is on the approach, where positional accuracy is critical. Aircraft using GPS/WAAS signals will be able to be located vertically and laterally within two meter, with very high reliability. By contrast, GPS approaches rely on on-board equipment for vertical location and so are considered non-precision. The FAA calls this new level of service, lateral precision, vertical guidance (LPV). It is also close to the CAT-1 minimums for approaches. WAAS approaches can be tailored to any runway, but justification needs to be made for the design of one. Increased usability is a generally accepted benchmark. Future developments in WAAS depend on how and if the system is supported by additional operators, including the International Air Transport Association. Supporters expect it to eventually catch on, just as GPS supported approaches did starting in 1994." @default.
