Abstract
View PresentationSignificant WAAS advancements in 2006
Track: GPS Technology
Author(s): Eric Gakstatter
WAAS (Wide Area Augmentation System) has quickly emerged as a significant source of accurate GPS corrections for mapping-grade work. 2006 is one of the most important years for WAAS in the GIS community. Two more broadcasting satellites will become available and 13 new ground stations will come online to enhance the WAAS service area in North America.
This is an in-depth look at WAAS from a GIS-perspective including the benefits, drawbacks and 'Gotchas'. Particular attention will be paid to WAAS satellite visibility and reliability as well as GPS receiver performance comparisons with USCG beacon and post-process differential correction.
As a practical example of applying WAAS-corrected data, the author will present how ArcPad was used in the construction layout, construction monitoring and as-built production of an 18-hole golf course.
