Today marks the 10th anniversary of the end of Selective Availability.
Until it was turned off on May 1, 2000, GPS signals available to the
public were only accurate to within 100 metres. In hindsight,
especially when you consider how pervasive GPS is in electronics today,
it may have been one of the most significant acts of the Clinton
administration. Just imagine what we couldn’t do it SA was still in
effect. AnyGeo, GPS Tracklog.
