Selective Availability (SA) of the Global Positioning System (GPS) was tested from March 25 to August 28, 1990. The objective of SA is to degrade the positioning accuracy of civilian GPS users by intentionally adding errors to the broadcast ephemerides and satellite clocks of the GPS navigation message. SA is expected to be fully implemented by about mid-1993. Presently, only Block II GPS satellites have full SA capability.
