The Evolution and Global Impact of GPS Technology
GPS technology originated from military needs after Sputnik's launch, evolving into a vital global navigation tool. Initially restricted to defense, GPS became available for civilian use in 2000, with 31 satellites ensuring global coverage. It plays a crucial role in navigation, fleet tracking, and personal devices, transforming everyday life and commercial operations worldwide.
The Evolution and Global Impact of GPS Technology
Innovation often stems from necessity, especially in wartime. The development of the Global Positioning System (GPS) was initially driven by military needs. Following Russia’s launch of Sputnik in 1957, scientists at Johns Hopkins Laboratory in Maryland sought ways to determine the satellite’s location in orbit, leveraging the Doppler Effect. This challenge spurred extensive research, eventually leading to the creation of GPS. Originally intended for defense, GPS found civilian applications over time, becoming widely accessible after a presidential order in 2000 eliminated selective encryption. Currently, a constellation of 31 satellites provides precise positioning globally, aiding navigation, fleet management, and many personal uses.
