SA Watch Description
SA Watch is a compact program that is designed to help you monitor and analyze the variation of the data that a GPS receiver registers when it is in a fixed location. Originally, this wandering was largely the result of SA - Selective Availability - DOD- speak for the deliberate degradation of the accuracy of your GPS signal. When SA was eliminated as a source of position error, we got our first good look at the remaining errors. SA Watch lets you see these graphically and statistically.
