Selective Availability (SA)

In the past, the civilian GPS signals were intentionally degraded, and a more accurate Precise Positioning Service was available only to the United States military, its allies and other, mostly government users. However, on May 1 , 2000 , then US President Bill Clinton announced that this "Selective Availability" would be turned off, and so now all users enjoy nearly the same level of access, allowing a precision of position determination of less than 20 meters.
