Global Positioning System or GPS Technology is not a one-day-developed and implemented research. Like any other systems, GPS developed through time, and continuously developing to further cater the needs of the sectors it supports.

 During the early 20^th century, the early type of GPS called the Ground-based Radio-navigation Systems was used. LORAN and Decca NavigationSystem have been helpful tools during the Second World War as a vital defense technology and later on used for commercial applications.

October 4, 1957 is marked as an important date when Sputnik, recognized as an “artificial star” was launched by the Soviet Union. Sputnik has been the way how researchers verified that satellite’s position could determine a subject’s position using its emitted radio signals.  
 1996 is an extraordinary year of GPS breakthrough, when Whitehouse announced that a higher level of GPS accuracy is already available for everyone, including the civilians. Development of the system constantly flourished as a lot of researchers found it helpful and interesting.
