WAAS Service Expanded into Canada and Mexico
September 28, 2007 - Today, the FAA GNSS Program Office announced that WAAS service is now available to users throughout Canada and Mexico.
This expansion was achieved by the integration of nine new international wide-area reference stations (WRS) into the WAAS network. The new WRSs are located in Canada (Goosebay, Gander, Winnipeg, and Iqualuit) and in Mexico (Mexico City, Puerto Vallarta, Mérida, Tapachula, and San Jose del Cabo). In addition to extending WAAS coverage to users throughout Canada and Mexico, this expansion also benefits WAAS users within the U.S. who were formerly on the fringes of WAAS coverage.
The incorporation of the Canadian and Mexican WRSs meets two of the FAA Administrator's Flight Plan goals for 2007. The first flight plan goal required that four of the international WRSs be operational by the end of September 2007. The second goal required that the remaining five international WRSs be operational by December 2007, a goal which was met four months ahead of schedule.
This significant milestone for satellite navigation would not have been possible without the commitment and valuable contributions of the Canadian and Mexican aviation authorities who have supported this work at the highest levels under the auspices of the North American Aviation Trilateral Agreement.
INMARSAT AOR-W satellite (PRN # 122) and POR satellite (PRN #134) to be phased out
July 2007 (Update) - The Atlantic Ocean Region - West (AOR-W) satellite represented by PRN #122 and the Pacific Ocean Region (POR) satellite represented by PRN #134 will cease WAAS signal-in-space (SIS) transmission on July 30th, 2007.
New WAAS GEO broadcast to begin in July
July 2007 - The WAAS broadcast from the Telesat geostationary satellite (PRN #138) will be operation (in Normal mode) and usable by WAAS avionics receivers on July 11. The orbital location of Telesat provides even better WAAS performance to the East Coast (high elevation) and also extends WAAS signal-in-space (SIS) coverage into northeastern Canada.
Test of future performance enhancements of WAAS to temporarily limit coverage in the Northeast
Between April 16th and 23rd, the FAA will be conducting a test of upcoming performance enhancements on the newest Wide Area Augmentation System (WAAS) GEO satellite, the Intelsat Galaxy XV.
WAAS aviation coverage during April 2007 testing
During this test, the Galaxy XV satellite will be unusable by aviation users. The POR & AOR-W satellites will continue to broadcast corrections and integrity information for GPS.
For the duration of the test, WAAS will be unavailable in the Northeast U.S, including all of Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, Connecticut and parts of New York. Accordingly, all uses of WAAS for Instrument Flight Rules (IFR) navigation (including LPV, LNAV/VNAV, and enroute) will be affected for a temporary period in the area impacted by the test. Aviation users should continue to refer to the most recent NOTAMs to determine the level of service at a specific airport.
No impact is expected for the remainder of the U.S. Service will be fully restored no later than April 24th when the test period expires.
WAAS aviation coverage to the Northeast will resume following testing
Garmin® Receives WAAS Certification for GNS 400W/500W series
November 9, 2006 - The GNS 400/500 series have earned the FAA's TSO C146a Gamma-3 certification, which enables pilots who upgrade their Garmin receiver to fly Localizer Performance with Vertical (LPV) guidance approaches and receive GPS navigation via the Wide Area Augmentation System (WAAS). This upgrade will allow thousands of Garmin 400 or 500 series receivers to utilize WAAS starting in 2007. See the Garmin news release for more information.
WAAS approved for new, lower minimums
March 2006 - In a major step that expands the benefits of satellite navigation for aviation users, the Federal Aviation Administration has announced lower localizer performance with vertical guidance (LPV) approach minima through the use of the Wide Area Augmentation System (WAAS). WAAS is now approved to provide guidance down to 200 feet above an airport's surface for LPV instrument approaches.
