WAAS

See also: GPS Links

While intended primarily as an aid to aviation (funded by the FAA), WAAS can also provide greater accuracy for handheld GPS receivers on the ground.

Almost all GPS receivers purchased in the last 5 years are now WAAS enabled.

There are currently 4 WAAS satellites that may be visible from Bellingham.

Originally, there were two satellites (one east coast and one west coast). More recently one of these has been moved and two new satellites have been added.

New satellites were slated to be in test mode during early 2007 and online by mid-2007.

 * Approximate azimuth and elevation from Bellingham, WA

 * For Azimuth, north is 0 and the degrees count clockwise

 ** AOR-W used to be the USA east coast WAAS but was moved in 2006

 *** (Also referred to as PanAm) - Scheduled to be available by "mid-2007"

 **** Scheduled to be available by Spring 2007
