History of Global Positioning System (GPS)

Global Positioning System (GPS) is a system to determine your current location with high level of precision. This is possible via a number of satellites working together to determine a client’s location.

The history starts in mid-1960s when United States military experimented with their own network of satellites and submarines. It took few minutes for the setup to determine the exact location of a particular submarine on the earth surace.

The first satellite for GPS is launched in 1978 and the overall system with a strength of 24 satellites became fully operatonal in 1993.

In its early days, the US military made GPS exclusive for their use only. These days, a good smartphone can use GPS up to about 4.9m accuracy.
