The US Government has announced that it is to stop the intentional degradation of GPS signals available to the public (known as Selective Availability) with immediate effect. This will mean that civilian users of GPS will be able to pinpoint locations up to ten times more accurately than previously.
The statement says "originally developed by the Department of Defense as a military system, GPS has become a global utility. It benefits users around the world in many different applications, including air, road, marine, and rail navigation, telecommunications, emergency response, oil exploration, mining, and many more. Civilian users will realize a dramatic improvement in GPS accuracy with the discontinuation of SA. For example, emergency teams responding to a cry for help can now determine what side of the highway they must respond to, thereby saving precious minutes. This increase in accuracy will allow new GPS applications to emerge and continue to enhance the lives of people around the world."
The US Goevrnment aims to continue to make GPS more responsive to civil and commercial users worldwide. Plans are in hand to modernise it by adding two new civilian signals to enhance the civil and commercial service and to add some new features on up to 18 additional satellites that are already awaiting launch or are in production. GPS capabilities will continue to be provided worldwide users free of charge.
The capability to 'selectively deny' GPS signals when US national security is threatened remains.
