WebThe signals transmitted by Block II satellites of the Global Positioning System (GPS) can be degraded to limit the highest accuracy of the system (10 m or better point positioning) to authorized users. This mode of degraded operation is called “Selective Availability” (S/A). S/A involves the degradation in the quality of broadcast orbits and satellite clock … WebTo prevent enemies from accessing the navigation signals, the U.S. military employed dithering: intentional interference with the satellites' timing signals that unauthorized users couldn't decode. This limited civilian GPS accuracy to about 300 feet (100 meters).
