Abstract

Em meados de 1991, foi introduzida pelo Departamento de Defesa dos Estados Unidos, propietário do sistema GPS (Global Positioning System), uma degradaçăo da precisăo instantânea de posicionamento. Chamada de SA (Selective Availability), esta adulera propositadamente as informaçőes dos satélites, inviabilizando o posicionamento com precisăo em tempo real.
