History of the GPS


Evolution

The GPS (Global Positioning System) has been used over time for many organizations. First, it was used in the U.S Department of defense to navigate the military around the 1970s, and in 1978, the first completely operational sattelite was launched. However, when it was finally released to the public, its accuracy was limited by something called Selective Availabilty.

However, in 1983, Korean Airlines Flight 007 crashed, causing President Reagan to cut Selective Availability for civilian use. Because of this, the 2000's had a breakthrough in GPS technology, such as location tracking for phones, Google maps, and even delivery driving apps!
