GPS Anchor Alarms


There is a fair amount of accuracy/repeatability difference between GPS with selective availability off and WAAS. Have a look at this URL an I think you will agree.

The graph was origianlly built as part of the (former parent company Raytheon) work with the FAA on WAAS.

The Garmin line of GPS receivers is/has gone exclusively to WAAS.
