Enviado para você por termal12 através do Google Reader: 10 Years Since the End of Selective Availability via The Map Room de Jonathan Crowe em 01/05/10 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. 10 Years Since the End of Selective Availability first appeared on The Map Room: A Weblog About Maps on May 1, 2010.
