WAAS coverage expands to Canada and Mexico
On September 28 2007, Wide Area Augmentation System (WAAS) coverage was expanded
into Canada and Mexico, according to the Federal Aviation Administration.
This achievement was made possible by the integration of nine new international wide-area reference stations (WRS) into the WAAS network. In addition to extending WAAS coverage to users throughout large portions of Canada and Mexico,
this expansion also benefits the U.S. WAAS users within the U.S., formerly on the fringes of WAAS coverage, are now well within its coverage boundaries.
