History of GPS

History of GPS

The United States military first used GPS as a navigation tool in the 1970s. In the 1980s, the U.S. government made GPS available to the general public, free of charge, with one catch: A special mode, called Selective Availability, would be enabled to purposefully reduce the accuracy of GPS for public users, reserving only the most accurate version of GPS for the military.

In 2000, under the Clinton administration, selective availability was turned off, and the same accuracy that the military had benefited from was made available to the general public.

What is GPS?

The Global Positioning System (GPS) is a space-based satellite navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. The system provides critical capabilities to military, civil and commercial users around the world. It is maintained by the United States government and is freely accessible to anyone with a GPS receiver.

The GPS is a satellite-based navigation system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense. GPS was originally intended for military applications, but in the 1980s, the government made the system available for civilian use. GPS works in any weather conditions, anywhere.
