When Did GPS Start Being Used?
The Dawn of Global Positioning
The birth of the Global Positioning System (GPS) traces back to the 1973 launch of the first NAVSTAR satellite by the United States Air Force. Initially developed for military navigation, GPS gradually entered civilian life in the 1980s.
Civilian Access to GPS
In 1983, President Ronald Reagan made GPS available for civilian use, albeit with degraded accuracy known as Selective Availability (SA). In 2000, the Clinton administration eliminated SA, enhancing GPS for civilian applications.
When Did GPS Start Being Used on a Large Scale?
By the early 2000s, GPS had become an integral part of everyday life. The availability of GPS-enabled devices exploded, including smartphones, car navigation systems, and wearable gadgets.
