What is WAAS?
The Wide Area Augmentation System (WAAS) is an FAA-funded
project to improve the overall integrity of the GPS signal and
increase position accuracy for users in North America.
The system is made up of satellites and approximately 25 ground
reference stations positioned across the United States that monitor
GPS satellite data. Two master stations, located on either coast,
collect data from the reference stations and create a GPS data
correction message. According to the FAAs Web site, testing in
September 2002 of WAAS conrmed an accuracy performance of 1–
2 meters horizontal and 2–3 meters vertical throughout the majority
of the continental United States and portions of Alaska.
WAAS is just one service provider that adheres to the MOPS
(Minimum Operational Performance Standard) for global Satellite
Based Augmentation Systems (SBAS). Eventually, there are several
services of worldwide geostationary communication satellites and
ground reference stations.
All SBAS systems use the same receiver frequency; therefore, any
operational SBAS system should be capable of providing your GPS
unit with increased accuracy at any location in the world.
Currently, enabling WAAS on your Garmin GPSMAP 276C in
regions that are not supported by ground stations might not improve
accuracy, even when receiving signals from an SBAS satellite. In
fact it can degrade the accuracy to less than that provided by GPS
satellites alone. For this reason, when you enable WAAS on your
Garmin GPS receiver, the receiver automatically uses the method
that achieves the best accuracy. To enable WAAS, see page 6.
